Insulation of a private house with polystyrene foam and siding. The scheme of wall insulation with polystyrene foam from the outside and the optimal thickness of the insulation for a brick house for siding. Material Choice: The Benefits of Styrofoam

Finishing houses with siding has become very popular in our country and around the world. The most common types of siding are metal and vinyl.

Thermal insulation of the house with foam plastic provides a number of advantages, such as: excellent thermal insulation, good sound insulation, a significant reduction in heating costs.

Additional insulation plays important role in our climate.

Since siding is an excellent protection for any thermal insulator, external wall insulation with foam will be very advisable. In addition to polystyrene, extruded polystyrene foam can be used. It is very important to insulate the house from the outside. Without this, brick or stone may collapse. External insulation is one of the most important moments when building a new house or when renovating an old one. Siding is used to protect the thermal insulation layer.

Materials for insulation

Scheme of the wall pie for siding: 1- load-bearing wall; 2- crate; 3- thermal insulation; 4-air gap; 5 - membrane; 6- siding.

Polyfoam (expanded polystyrene) is an environmentally friendly, practically harmless material. It is from it that a variety of disposable tableware And different kinds packaging for long-term storage products.

Styrofoam is easy to cut and very easy to use. Its porous structure consists of independent cells. The foam is small specific gravity. It has high thermal insulation, physical strength and fire resistance.

Polyfoam is one of the highest quality heat insulators. In terms of price and quality ratio, this material is better than other building insulation materials. In our country, external wall insulation with foam plastic for siding is currently very popular.

Extruded polystyrene foam is a high-density slab with a honeycomb structure closed type. Plates are obtained by extrusion, a foaming agent is introduced into the melted polystyrene. Extruded polystyrene foam has the lowest thermal conductivity of all materials used in construction. It is very easy to insulate a building with polystyrene foam. It absolutely does not absorb moisture and has increased compressive strength.

Foamed polyethylene is made from a composite material based on polyethylene in a high pressure zone. Flame retardants (additives that extinguish fire), dyes and foaming agents are used to form gas.

Wall preparation

Scheme of wall insulation with foam plastic for siding.

Installation of siding outside the house can be carried out throughout the year. When installing vinyl siding, the air temperature should not be less than minus 10°C. In the cold, vinyl becomes brittle and may crack during installation. Work on the insulation of the facade from the outside under the siding is carried out with the installation of the crate on a brick or stone wall. The crate can hide defects or uneven walls. There are no additional requirements for the process of preparing the surface of the walls. All objects outside the house that can interfere with work must be dismantled: plants touching the walls and climbing them, lamps, drainpipes and window shutters. The house must be absolutely cleaned from the outside, then it will be easier to insulate it.

In order to securely fix the insulation on the wall, it is necessary to assemble the crate, which is a frame. The frame can be assembled from wooden beams or from galvanized metal profiles. The cost of material for a metal frame is somewhat more expensive than wooden beams, but the service life of a metal crate is much longer.

Lathing installation

Step-by-step installation of polyfoam: 1- preparation of the facade; 2- profile installation; 3- applying glue to the foam; 4- gluing foam to the surface; 5- fastening with dowels; 6- installation of corner reinforcing parts; 7- reinforcement; 8 - protective and decorative layer.

Depending on the layer and thickness of the insulation, the thickness of the crate is also selected. If wood is used for the frame, the surfaces of the timber must be treated with an antiseptic or flame retardant. The wall under the crate, stone or brick, should be smeared with waterproofing mastic or covered with a waterproofing film. The beam for the frame must be made of coniferous wood.

If the siding is mounted horizontally, the sheathing must be filled in a vertical position, and vice versa. And for mounting vertical siding, the frame must be horizontal. The profiles must be installed on a brick or stone wall in increments equal to the distance between the siding mounting holes.

An additional crate is installed at all corners of the building, near window and door openings. The verticality and horizontality of the crate is checked using a level. The subsequent installation of siding and its correctness entirely depend on the flatness of the crate and frame. You need to fasten the profiles to the walls with screws with plastic dowels. It is recommended to screw a galvanized screw into a brick or stone outside the house. If the walls are wooden, then galvanized nails with a length of at least 100 mm are used.

The correct calculation of the thickness of the insulation will allow you to maintain the desired temperature in the house, even taking into account adverse weather conditions. The thickness of the insulation is calculated depending on the region in which the house is located, the material from which the walls of the house are made, the construction of the walls and the characteristics of the insulation itself.

Insulation is laid directly on the stone or on the brick in the space between the profiles of the crate. You need to fix the insulation to the wall with glue and dish-shaped dowels with a large head. After that, the insulation must be covered with a diffuse membrane. It will prevent the penetration of moisture to the insulation from the outside and ensure the removal of water vapor from the insulation. The membrane must be fastened to the crate with an air gap of 25 to 50 mm. To create such a gap throughout the crate, it is necessary to fasten a wooden bar or galvanized profiles. Such a membrane is very combustible, and the combustion process occurs at a high speed, so it is desirable to install it, but not necessary, and the decision is up to you.

It is considered very effective to insulate the facade in 2 layers. Installation of foam on the second layer is carried out using glue and plate-shaped dowels. Upper layer insulation must be laid with overlapping of all seams of the lower layer. Thus, cold bridges will be eliminated. The house will be insulated much better.

1. Wall insulation with foam plastic for siding is successfully performed both in new construction and in the alteration and reconstruction of already built buildings.
2. When performing work on insulation, additional attention should be paid to window and doorways. Such a layer of insulation will necessarily lead to the fact that in the house all the openings will be slightly recessed inwards.
3. You can get out of this situation by replacing windows and doors or window and door frames to new ones with a larger width.
4. Facing with siding with foam insulation will not only provide thermal protection, but also significantly increase the life of the walls.
5. You can insulate the house in other ways, but this one is more economical and practical.

After completing the installation of the frame of the crate and laying the insulation, proceed to sheathing the house with siding.

Insulation of the walls of buildings and premises is a very topical issue in modern conditions. This provides many benefits, such as saving heat in the house, creating a cozy atmosphere and saving on heating. This is especially true for northern latitudes, but may make sense in milder climates. You can install a layer of insulation not only during the construction of a new house, but also to improve the heat-saving characteristics of an already finished building. For these purposes, you can use such time-tested materials as stone or plaster, or you can keep up with the times and mount insulation for the walls of the house outside under the siding.

Penoizol is great for wall insulation under siding

There is an opinion that only brick or panel houses. However, in wooden houses, with all the advantages of the material, standard thickness logs are usually not enough to significantly save on heating. Four main types of materials can be used as insulation for the walls of a house outside under siding:

• Styrofoam;
• mineral wool;
• ecowool;
• penoplex.

Each of these materials has its own advantages and disadvantages, as well as installation features.

An example of installing insulation and siding on a wooden house

Styrofoam - easy to install and cheap insulation for the walls of the house

If you use polystyrene foam as a heater for the walls of the house outside, you can significantly save cash. This material is both light and rigid, so it can simply be glued to the wall with construction adhesive. Another option for fastening foam panels is dish-shaped dowels.

Unfortunately, the useful properties of polystyrene as a heater end at ease and easy to install. Yes, and the issue of saving is sometimes very controversial, because mineral wool is getting cheaper every day. The ventilation characteristics of the material also leave much to be desired. If you use it as a wall insulation from the outside, then please note that you will additionally have to organize mechanical ventilation to remove excess moisture from home.

Scheme of arranging thermal insulation for siding using polystyrene foam and Magaflex

You can often hear that the foam as a heater works as an excellent soundproofing. This is also not entirely true. It isolates walls from external noise no better than other heaters, moreover, if you fix it too hard, it will act as a sound-amplifying membrane.

Helpful advice! It is not very rational to use polystyrene foam as insulation for residential premises, but for insulation engineering communications or gender it will fit perfectly. In such cases, the place will have its low thermal conductivity and minimal water absorption.

Insulated Vinyl Siding - Sectional View

The service life of foam panels is 10-15 years, like all polymers. After this period, it may simply collapse, and you will have to mount a fresh layer of insulation for the walls of the house outside under the siding.

As can be seen from all of the above, the foam has a number of useful properties for warming various communications, but poorly suited for thermal insulation of residential premises.

Siding is mounted on a crate, inside which you can place a heat insulator

Insulation of houses outside with mineral wool for siding

Mineral wool, like ecowool, is a versatile material for home insulation and is great for wooden, block or brick walls. Mineral wool and ecowool are materials that are very similar in their characteristics and properties, so below we will consider their common features.

If you are interested in the price of insulation for the walls of the house outside, then mineral wool can cost a little more than polystyrene foam, but this is more than offset by its excellent performance. It goes very well with plastic or metal siding. If you are using a wooden crate for siding or an iron frame, then remember that you do not need rolled mineral wool, but semi-rigid slabs. Optimal size slabs for cladding - a meter by half a meter. This is due to the fact that mineral wool or ecowool in rolls is more difficult to fix, and over time it can slide along the wall, opening up its individual sections.

Mineral wool is suitable for insulating wooden, concrete and brick walls.

Mineral wool is a material that is quite dusty. In order to avoid this, you can additionally protect the boards with a vapor barrier film. It will perform two functions: do not let air small particles cotton wool and it is good to pass water vapor, which, in any case, will penetrate from the walls of the house.

If we consider the question, which insulation is best for walls wooden house outside under the siding in terms of environmental friendliness of the material, then ecowool is in the lead. It is made from cellulose, but with the use of special additives that increase its level of fire resistance and corrosion resistance.

Scheme for arranging thermal insulation of a wall using mineral wool

Ecowool, however, has one significant drawback - it is produced only in a format that requires the use of special equipment to install it on the walls. There are no panels on the market yet that can be fixed to the wall with building glue or dowels. But if you look at the photo of finishing houses with siding using ecowool, you can see that it fits very tightly to the walls, does not float over time and does not deform.

According to the parameters of sound and heat insulation, mineral wool and ecowool are identical. Due to their loose structure, they perfectly contain sound waves and do not let heat out of the house. When warming brick house outside with mineral wool for siding, you get rid of the problem of street noise, even if you live near a highway or in a busy place in a big city.

Ecowool has high sound and heat insulation properties

Helpful advice! If you compare the price of such insulation for the walls of the house outside under the siding, like ecowool with polystyrene foam or mineral wool, then you should also take into account the cost of application. In ecowool, it is quite high.

If you need to familiarize yourself with the video of wall insulation outside with mineral wool for siding with your own hands, then it can be easily found on the Internet. Videos with the participation of specialists will help to better understand the nuances of installing insulation.

The crate simultaneously serves as a support for insulation and a frame for mounting siding

The subtleties of warming the house outside with foam

Penoplex is relatively new material, which, according to its performance characteristics, can give odds to all of the above materials. It differs not only in high rates of thermal insulation, but also in versatility in application. If you are interested in the question, what is the thickness of the foam insulation for frost 30 degrees. will be optimal, then the answer to it will pleasantly surprise you. Due to the high efficiency of the extruded polystyrene that makes up this special type of foam, a very thin layer of material is needed to reliably insulate the walls. In addition, it has low vapor permeability and water absorption, so you can not be afraid that the walls will "sweat".

Another advantage of foam plastic is a high level of corrosion resistance. It is also absolutely harmless to human health. Plus, it's very easy to install. The disadvantages of the material include high flammability, therefore, if you plan to insulate houses from the outside with foam plastic, then it is better to take care of increased measures fire safety.

Do-it-yourself wall insulation with penoplex

At the moment there are 4 types of penoplex:

• roof - used for insulation various types roofs;
• comfort - a universal type, which is most often used for warming private houses;
• foundation - used in loaded structures, can be used to insulate the basement of the foundation from the outside;
• wall - can be used for external or internal wall insulation.

There are also special ultra-dense types of foam that are used in industry.

Insulation for the walls of the house outside under the siding: installation steps

Regardless of whether you need to insulate the outside under the siding log house, brick or block, it is necessary to adhere to certain installation rules.

• step 1. The surface to be insulated must be prepared. All walls must be removed old cladding, as well as dismantled shutters, drainpipes and other structures that may interfere with the installation of insulation. If you use a frame for siding from a profile, then the coating will be even in any case, so there is no need to level the walls;

Steps 1 and 2: preparing the wall and arranging the wooden crate

Helpful advice! If the walls of your house are old and have many cracks and defects, then by installing insulation for the walls of the house outside under the siding, you simultaneously increase the thermal insulation properties of the building and improve its appearance.

• step 2. Installing the crate for siding with insulation is very milestone installation. It can be made from metal frames or wooden blocks. The first option will cost more, but it will last longer. The thickness of the crate and the distance between its elements depends on the size of the insulation. It is recommended to additionally cover the wooden crate with a fire retardant compound to increase the level of fire safety of the building. Horizontal siding should be mounted in a vertical position, and vertical siding in a horizontal position. The accuracy of the design is regulated using the building level;

Step 3: Mounting thermal insulation material on the walls of the house

• step 3. The next step is to insulate the wooden house from the outside under the siding with mineral wool or other material. The main thing here is to ensure the tightest possible fit of the material. For fastening, construction glue or dowels with a large head are used. A waterproofing is mounted on top of the thermal insulation, which serves to remove vapors from the insulation. Usually, a special membrane is used for this, which is attached directly to the crate;
• step 4. Installation of siding is the final stage. If you are in doubt about how to do it right, then photos of finishing the house with siding from the outside will help you.

Step 4: choosing the right type of siding for the subsequent cladding of the facade of the building

Regardless of the type of material chosen, insulating a house for siding will allow you to significantly save on heating and improve the appearance of the building. Buying insulation for the walls of the house from the outside is very important point, so you should first familiarize yourself with the features and performance characteristics of each of the materials.

Siding is a good protection for any thermal insulator. Therefore, finishing with foam plastic, followed by cladding with vinyl panels, is very advisable. Insulation of a building from the outside can be attributed to one of the main stages in the construction of any house, since without additional protection, wood, brick and even reinforced concrete will gradually collapse under the influence of harmful factors environment. The use of siding can qualitatively extend the life of bearing walls any design.

A little about foam

Installation of expanded polystyrene boards under siding is a cost-effective solution for creating an optimal heat-insulating layer. In addition, the material has good sound insulation characteristics, is environmentally friendly and does not burn.

Despite the fact that expanded polystyrene is not combustible, it melts under the influence of high temperatures or open fire. At the same time, combustion products are released into the atmosphere, which, if they enter the respiratory system of a person, can cause injuries incompatible with life.
Currently, two types are used in individual construction polystyrene boards, any of them can be insulated own house outside with subsequent finishing for siding:

• Ordinary foam;
• extruded.

The table shows the average values ​​of the coefficients of materials, depending on the manufacturer, they may differ slightly from those indicated.

Mounting technology

The shape and structure of both types is similar, so the principle will be the same for both insulation from the outside with polystyrene foam and foam. Before you start warming the facade, you need to treat it with an antiseptic. This will prevent the formation of mold and the appearance of insects in the walls that destroy the supporting structure.

Lathing plane definition

The next step will be marking the plane of the walls and determining the location of the guides (this can be a wooden bar with a size of at least 20x30 mm or a galvanized profile 60x27 mm). Since the exterior cladding is made using siding (which is usually installed in a horizontal position), the guides must be mounted vertically.

An exception is metal siding or block house. Its installation can be carried out both horizontally and vertically in relation to the ground.

Vertical plumb lines are hung at the corners of one wall, with the help of which the location of the two extreme guides is determined. Then two ropes, fishing lines are pulled between them (top and bottom). It is for them that the subsequent installation of the remaining elements of the crate is carried out.

useful at work

Some manufacturers of plastic exterior wall siding offer vertical panels to their customers. Their installation is carried out on a horizontal subfacing system.

Mounting rails

Insulation of the walls of a residential building, followed by finishing for siding, is carried out with a step between the guides of at least 40 cm. Fixation is carried out using galvanized brackets or (if a wooden beam is used) with self-tapping screws.

Despite the fact that the construction of a metal sub-facing system is more expensive from the outside than the installation of an analogue made of wood, the service life of the former is much longer. Therefore, the right to choose which material to use for this remains with the owner of the house.

useful at work

When installing the crate from wooden beam you need to make sure that the wood is dry. In addition, work in the wet rainy weather can lead to swelling of the structure and subsequent drying and warping.

Installation of thermal insulation

As mentioned earlier, the characteristics of polystyrene foam and polystyrene foam are almost identical, so the fixing method is described alone. Wall insulation with plates is recommended to start from the bottom row and gradually rise. First of all, whole sheets are laid, small openings are closed afterwards.

To ensure better fixation, the foam with the help of fungi - umbrellas is attached to the wall of the house. It is desirable to attach plates in each corner and at least one anchor should hold the insulation in the center. It is allowed to place anchor elements in the seams of the material, thereby “pressing” two sheets of thermal insulation to the facade at the same time.

If the climatic conditions of the region in which the house is located require that the insulation be carried out in two or three layers, the imposition of one seam on another is not allowed. This can lead to the formation of cold bridges and the gradual wetting, freezing and destruction of the walls.

Insulation of the house with foam plastic, followed by cladding with siding, is one of the most economical and practical option exterior finish buildings made of any building materials. The method is actively used both in the construction of new facilities, and for the decoration and reconstruction of already built ones.

must be taken into account during installation. That all window and doorways will be slightly pressed into the walls. Thus, for their subsequent finishing, additional materials will be required, which are best purchased in advance.

• Internal or external corners (slopes, ebbs)
• Sandwich panel or PVC;
• Near window trims offered by the panel manufacturer.

Plastic (vinyl or acrylic) siding is mounted only with strict observance of technological requirements when working with the material:

• Work on finishing the exterior walls of the house is allowed only at an ambient temperature of at least 10 degrees above 0. In the cold, the panels lose their flexibility and may crack as a result of installation;
• Fasteners that fix the siding must be made of stainless steel or have a galvanized coating;
• Self-tapping screws are not wrapped all the way, this is done so that the panels can slightly shift under the influence of temperature changes (in the cold, the siding decreases in size by 1-2 cm, when heated, on the contrary, it increases);
• Screws are screwed only at a right angle of 90 degrees.

Just keeping everything necessary requirements you can create a high-quality and durable facade that can not only improve the characteristics of the walls, but also modify the whole house.

Today, the relevance of using such material as siding in modern construction is quite understandable: siding wall cladding perfectly hides all existing defects, makes the appearance of the house more attractive, and at the same time it has a relatively low price compared to its counterparts. The main advantage of such wall cladding is that it provides for the installation of heat-insulating materials.

In this article, we will talk about the benefits that insulation provides for walls outside the house under siding, installation technology, price, find out reviews and opinions of people, and much more, which will help you decide on the best insulation for walls outside the house or cottage.

Types of heaters

• Insulating materials for walls based on mineral wool are sold in roll and slab form with different densities, which affects their characteristics and, of course, the price of the material.

Photo: slab and roll mineral wool insulation.

• Glass wool. Such insulation for walls outside the house for siding is made on the basis of fiberglass. Implemented in slab and roll form. This type of insulation for walls outside the house is widely in demand in private housing construction, as it has a low price, which makes the material affordable for all consumers.

Photo: glass wool in roll and slab form.

• Styrofoam. This type of insulation for walls outside the house is also very popular, though less than mineral wool and glass wool, but this does not mean that such insulation for the walls of the house is worse, it just loses to them in some respects, but in some ways the other way around. excels.

• Expanded polystyrene extruded. Such insulation for the walls of the house has good performance, which makes it widely in demand in modern construction. Insulation of a brick house from the outside with expanded polystyrene provides a high rate of heat saving.

It should be noted that it is not so easy to choose a heater for walls outside the house that would fully meet all the requirements, because each of them is effective with its own set of characteristics, both good and bad.

And in order to choose the right insulation for walls for siding, which would be more suitable in your case, be sure to take into account the climatic conditions, the type of walls that need to be insulated, and so on. Many people make a big mistake when, when choosing wall insulation for siding, they pay attention only to the price, while they do not even think about what degree of efficiency a wooden house will be provided with such wall insulation.

That is why, in order to know exactly which insulation is best for your home, carefully read the reviews of people who have had to deal with the work of insulating the facade of a wooden house.

Below is a video clip, after watching which you will have an idea of ​​​​how the external insulation of a house under siding is carried out with your own hands:

Styrofoam. This is a very good, and most importantly, low-cost siding insulation for a brick house, which has high thermal insulation characteristics. Among the advantages of such a heater for siding, one should especially highlight its excellent moisture resistance, low thermal conductivity, low price and ease of installation not only outside, but also inside, for example, a log house, its installation can be carried out on vertical and horizontal wall surfaces.

Now for the disadvantages. Styrofoam is such a heater for siding, which can disrupt natural air exchange inside a wooden house, since it has low vapor permeability. The walls of a wooden house, when lined with foam plastic, will not be able to “breathe”, because of this, moisture begins to collect between the walls and the insulation under the siding, which then appears in the form of condensate.

Also, the disadvantages of such wall insulation outside the log house include its fragility - the operating time of the foam is twelve to fifteen years. In addition, the foam burns, while releasing hazardous substances.

With regards to the sound insulation of such insulation of a log house outside under the siding, it cannot boast of this either, since it actually amplifies the sound even more, acting as a resonator. Therefore, before choosing such insulation for the facade of a wooden house, weigh the pros and cons well, read the discussions about the material, and only then decide the issue with its choice.

In the photo above, you can see how the facade of a private house is insulated with foam.

Mineral wool. Such insulation for siding, as well as its varieties, which include basalt wool and glass wool, can be called the best heat insulator that is successfully used for external insulation of a house under siding, and it doesn’t matter at all whether it is wooden or brick house, and in both cases it will provide high thermal insulation.

In terms of thermal insulation characteristics, mineral wool is not much inferior to polystyrene foam. The main advantage of mineral wool can be called the fact that it does not burn, this makes the insulation of a wooden house outside with mineral wool under the siding completely safe. In addition, all the modifications of mineral wool that exist today are vapor-permeable and, based on people's discussions, are considered the best sound insulator for the walls of a log house, and this says a lot. Below in the photo you can see the scheme of wall insulation with mineral wool.

In the photo you can see the insulation of the walls of a wooden house with mineral wool.

In the photo you can see a diagram of the “insulation cake” device on the walls of a wooden house.

Despite the huge number of advantages of warming a wooden house outside with mineral wool, the material has a big drawback, which is its hygroscopicity, which is seventy percent. Therefore, when insulating a wooden house outside with mineral wool, it will be necessary to apply waterproofing material. However, here too there is a big problem, that is, if an ordinary film is used for waterproofing, then in this case the vapor permeability of the mineral wool will come to naught.

To provide better protection insulation from moisture getting inside for waterproofing, it is necessary to use diffusion membranes, in which the vapor permeability index will be from four hundred to a thousand g / m² per day or more.

The use of such waterproofing by fifteen to twenty-five percent will increase the estimate for wall insulation from the outside under the siding of a wooden house or cottage. Also of the minuses, it should be noted that mineral wool, when insulating a house, can cause allergies, as it “dusts” very much, so it is better to use it only for insulating walls outside a brick house, and not inside.

Extruded polystyrene foam. The material is successfully used for warming a wooden house. The main advantage of expanded polystyrene can be called its ease of installation and durability, it can last thirty years, and even more. Unlike polystyrene, such insulation outside the house for wall siding has higher strength characteristics.

Air cells in the structure of extruded polystyrene improve its thermal insulation properties. The only big minus that is inherent in this insulation is a high degree of fire hazard, and not only the fire itself is terrible, but thick suffocating smoke, which causes poisoning. That is why it is better not to use it to insulate a house or cottage whose walls are built of wood.

Extruded Styrofoam compresses very badly, which makes it resistant to breakage, and if it happens that, for example, log house will begin to shrink, then in this case the expanded polystyrene installed on the walls will not crack and crumble. In addition, the insulation has good resistance to moisture and temperature extremes. From the numerous reviews of people, one thing can be understood, that such wall insulation from the outside with foam plastic for siding for a house is one of the best options.

In the photo you can see the insulation with extruded polystyrene foam.

Photo: installation of extruded polystyrene foam on a brick wall.

Looking at the table, you can see that all these materials for insulating a house under siding have a very similar thermal conductivity coefficient. The highest characteristics are inherent in basalt wool, which makes this material the best option for warming the outside of the house with mineral wool for siding, and it can be used to insulate brick, timber and wooden houses for siding.

Home insulation technology under siding

Currently, there are several technologies that allow you to install insulation outside the house with mineral wool for siding with your own hands at little time. The first option for insulating a brick house with mineral wool can be considered really budgetary, this is when simple insulation materials in rolls are used for insulation, their installation is as follows: the insulation is glued to the wall surface and then fixed to it with the help of the crate made. Judging by the reviews of many people, this technology is currently simple and affordable.

The next installation option is do-it-yourself inter-frame insulation of a log house for siding. Here, insulating boards of increased rigidity are used as a heater, the installation of which is carried out in the cells of the previously made crate for siding and fixed to the wall surface with screws or glue. The mineral wool installed in the cells of the crate will lie flat and hold well on a brick wall.

The photo shows a diagram of the device for interframe two-layer wall insulation.

There is another technology for insulating a log house - installation on a cross frame. It must be said that it is this technology of warming a log house, according to experts, that is the best, but the price of work and materials in this case will be rather big.

The fact is that with this technology, the installation of insulation takes place in several stages: first, a crate for siding is fixed to the surface, it is filled with insulation, then another crate is installed on it and also filled with insulation. Installation of the first crate for siding with insulation is carried out vertically, and the second horizontally, so you can completely get rid of cold bridges.

Such insulation of the walls outside under the siding, although it turns out to be expensive, but it will always be warm in your wooden house. This technology is also well suited for the insulation of brick and concrete walls. Below you can see detailed video about how the installation of insulation for siding is carried out using a simple technology:

Which is better to choose a heater for siding: expert advice

Many who decide to insulate their wooden house very often ask themselves the question: what insulation for the facade is better to choose for siding and why? It is impossible to answer this question unambiguously, since all heaters for siding differ in their pros and cons.

For example, polystyrene foam and all its varieties are distinguished by good resistance to moisture, because they have a small degree of vapor permeability, but because of this, a stuffy effect will always be present in a wooden house. But with regards to mineral wool, when it gets wet, it loses its inherent heat-insulating properties by fifty percent, therefore, during warming with mineral wool outside the house, it will be necessary to equip the insulation with additional protection using waterproofing materials.

Despite weak sides mineral wool today, based on numerous reviews, is considered the most best material for wall insulation outside under the siding of a wooden house, cottage. It must be said that such a facade insulation for siding, in combination with a waterproof barrier, can provide a timber house with excellent heat and sound insulation performance.

In addition, mineral wool is one hundred percent environmentally friendly, it can last for many years, while the cost of mineral wool is low, which makes such a facade insulation affordable for all buyers. With regards to the opinion of experts about mineral wool, they all unanimously assert that warming with mineral wool outside the house under siding is the most reasonable solution that can solve the issue of installing the best facade insulation of the house with your own hands.

Warming the house outside with mineral wool for siding with your own hands: step by step instructions

To make it clear to you how the insulation is installed, below we will present instructions for installing insulation for siding. So, if the insulation outside the house under the siding will be carried out using mineral wool, then in this case it is better to purchase rigid slabs and attach them to the surface of the walls in a wet way. Step-by-step instruction below will help you make facade insulation with mineral wool yourself.

• First of all, we need to fix a metal cornice in the lower part of the wall surface. This is necessary so that the insulation, in our case it is mineral wool, lays evenly, in addition, in this way you will provide better protection against rodents for insulation outside the house under siding, which, judging by the discussion of people, for some reason prefer mineral wool more than other materials.

• The wall on which the mineral wool will be insulated must be well primed.
• To make a reliable fastening to the mineral wool wall, we need polymer cement glue, it is not difficult to make it, you just need to pour water into the dry mixture and mix well until you get a homogeneous mass. Ready glue must be applied to the back side facade insulation.
• It will be necessary to fasten the mineral wool starting from the bottom and moving upwards in such a way that a dressing of the seams is formed (as with brickwork). During the installation of mineral wool, it is necessary to ensure that the plates fit well to each other. Mineral wool slabs glued to the wall surface should be additionally fixed with plastic dowels that have large caps, although this should not be done immediately, but wait one day. When fixing the facade insulation under the siding, you need to ensure that the plates do not move apart.

That's all, the insulation of the wooden house with mineral wool is ready. And to better understand how such work is done, read the reviews of people and watch the video instruction:

Insulation of the walls of a brick house with polystyrene foam

If you decide to insulate the walls with polystyrene foam, then such work is best done in the summer, when the weather is hot outside. By the way, mineral wool insulation is also best done in dry weather. The surface of the wall, which we will insulate with polystyrene foam, should be dry, that is, moisture should not get on it for three to four days before the installation of the insulation.

1. First you need to clean the surface of the wall well from the dirt on it, if there are irregularities, they also need to be removed.
2. As soon as the walls are prepared, they will need to be leveled, for this they use a primer.
3. We glue the sheets of insulation to the surface of the wall.
4. Next, you need to cover the insulated area with a primer, and only then you can proceed to install the siding on the walls of a wooden house.

The photo shows how to insulate brick walls with mineral wool.

Such wall insulation for siding will be very effective and will provide you with a comfortable existence even in the most severe frosts. The main thing is to properly insulate the walls with polystyrene foam on all sides of the wooden house, otherwise the insulation of the walls for siding will not be of high quality, therefore, drafts and cold will be present in the wooden house.

To prevent this from happening and you would not have to throw money away, you need to approach the work of insulating the walls with polystyrene foam responsibly and strictly follow the video instructions:

and then the result will not disappoint you. Installation of insulation for siding: step-by-step instructions

In order for the insulation with mineral wool or any other heat insulator to be done correctly, you need to follow the instructions and make the calculations correctly.

• For the installation of wall insulation for siding, it is required to take a heater, the thickness of which should be at least four to five centimeters.
• With the help of glue, the insulation for siding is fixed on the crate, which is installed on the surface. outer wall wooden house.
• Installation of insulation under the siding starts from the bottom to the top.
• As soon as the walls of the wooden house are completely lined with material, you can proceed with the installation of the siding.

Sheathing for siding with insulation

The cladding of the facade of a wooden house must begin with the installation of the crate. Currently the best and in an inexpensive way the use of bars or slats is considered, such a crate will allow not only convenient installation of the siding, but also the installation of insulation under the siding. The step of the wooden crate should be from thirty-five to forty-five centimeters. All wooden elements battens for the facade must be treated with a special antiseptic.

In the photo you can see the device of the wooden lathing of the facade of a log house, as you can see, everything is very simple here.

The need for crates is due not only to the fact that it is necessary to level the walls, but also to arrange a place for laying insulation.

There is another type of crate for facade insulation, it is made of metal. Such a crate for the facade will last for more than a dozen years. In order to be able to set the indentation you need from the wall surface, you will need to use special suspensions.

In the photo you can see the device of the crate for the facade of a brick house.

The photo shows the installation scheme of the crate and siding.

To better understand what a crate for a house for siding is, watch the video presented for you:

You can also read the discussions of people who made the crate for siding with their own hands. The price of work on the insulation of the facade for siding

Any of existing ways It is not difficult to do the wall insulation outside a wooden house for siding yourself, but if for some reason you cannot do this, then entrust such work to specialists. The cost of insulating a wooden house for siding will directly depend on how much work needs to be done. In the table below you can find the approximate price of insulation for the siding of the facade of a wooden house.

At some point, the owner of a private house realizes that the walls of his house do not cope with the task of retaining heat. This problem can only be solved by insulating the walls from the outside. At the same time, the wall of the house itself will be protected from moisture and direct sun rays.

Options for insulating the outer walls of buildings and the properties of the insulation

There are several options for organizing the external insulation of the walls of the house:

• The insulation is glued to the wall with a special adhesive. From above, the surface is covered with a layer of plaster.
• The insulation is glued to the wall. Then, observing a small gap, the wall is laid in one brick. This is one of the types of ventilated facade.
• Ventilated facade. Waterproofing is installed on the wall. A heater is arranged on top of it, and a hydro-wind protection is placed on it. On top of all this "pie" is mounted outer lining i.e. siding. These works can be carried out at any time of the year.

All types of modern wall insulation materials have their own characteristics. They differ from each other not only in the coefficient of thermal conductivity, but also in price. And the consumer pays attention to the following insulation features:

Given the characteristics of the insulation available to the owner of the house, the method of mounting it on the wall of the house is also selected.

The main types of wall insulation

Nowadays, as the main insulation for the walls of the house outside under the siding the following materials are used:

• Polyfoam (expanded polystyrene), foam plastic, polyurethane foam.
• Mineral wool.
• Basalt insulation.

The thermal conductivity of each insulation material can be visualized using the following comparative table. As a starting material for comparison, a standard brickwork 90 centimeters thick is taken.

Styrofoam (expanded polystyrene)

This is a modern insulation for walls and other surfaces.. It is used in all areas of industrial and civil engineering. It has a low coefficient of thermal conductivity. Resistant to chemical and biological influences, has high sound insulation. Durable and environmentally friendly material with a service life of more than fifty years.

Another advantage of foam sheets is their light weight and low price. Weight contributes to the low labor intensity of the work performed, does not load the walls, which eliminates the need for additional strengthening of the foundation. The disadvantage of this material is flammability.

Extruded polystyrene foam (foam)

Thermal insulation material of the latest generation based on graphite nanoparticles. Foam thermal conductivity coefficient is 0.03 W/m*K. Very resistant to mould, chemicals, insects and rodents. Excellent sound insulator. In addition to the insulation of the walls of buildings, it is used in the manufacture of the foundation of individual low-rise buildings according to the "insulated Swedish plate" technology. It is used for protective sheathing loggias and balconies, cellar walls.

polyurethane foam

Plastic with foam-cell structure. The proportion of air-filled cells in polyurethane foam reaches 90 percent of the total mass of the insulation. Because of this, its thermal conductivity is one of the lowest. Differs in good adhesion with all materials of surfaces: wood, concrete, metal and brick.

Thanks to this, an airtight coating with good hydrovapor barrier is created.

It is applied to the surface under pressure using a hose and a compressor. The plastic mass during blowing fills all cavities and cracks. The disadvantage of this insulating material is the high cost and the need for expensive equipment.

Mineral wool

This is a basalt insulation, glass wool, stone wool. A product of the processing of metallurgy waste and the processing of rocks such as dolomite and basalt. Differs in durability incombustibility, environmental friendliness, durability, elasticity. Low price and ease of installation. Absorbs sound well. You can install cotton wool at any time of the year. When insulating walls from the outside with mineral wool for siding, it does not require special skill.

The industry produces this insulation in rolls and in the form of plates. Roll insulation used for coating horizontal surfaces or surfaces with a slight slope. It is more convenient to insulate vertical walls with slabs. Mineral wool can be used in conjunction with blown polyurethane foam. Rolls and slabs are produced in the following sizes:

Liquid thermal insulation

These are new generation heaters.. Liquid thermal insulation materials are now insulated metal pipes, foam block houses and other structures. It is a multicomponent ceramic substance similar to acrylic paint. It only contains up to 80 percent of voids in its sticky mass.

It is applied to the surface to be insulated with an ordinary paint brush, roller or spray gun. When applied with a spray gun, it fills all the cracks and voids. After drying (at least six hours), it is resistant to mechanical stress, protects structures from precipitation and the sun, metal from corrosion.

Siding, its characteristics and types

They call it siding thin (from one to ten millimeters) type-setting panel parts for facing the facades of buildings and other structures with a length of two to six meters. The width of the siding is from ten to thirty centimeters. This is not only a decorative coating. In many cases, siding panels are an important part of a multi-layer insulated wall covering. And they are also mounted to improve the hydrothermal insulation of the entire structure, to protect against external noise.

Sidings are vinyl, wood, metal and cement. metal panels are made of steel and aluminum with a width of twelve centimeters to fifty-five centimeters. The surface is made perforated or without holes. Figured or smooth-smooth. Currently, wide smooth sidings are in demand. They are universal. They are mounted both vertically and horizontally. Metal siding is much more durable than vinyl siding, it is fireproof and requires no special maintenance. It is little affected by changes in ambient temperature.

wood siding are made by pressing wood fibers and binders under high temperature. During manufacture on the panel at high temperature apply paint at five. paint creates reliable protection. For environmental reasons in production wooden panels resins containing phenol-formaldehyde substances are not used. In appearance, they are much more attractive than other species.

Cement siding panels are made from cement mortar with the addition of cellulose. The surface is primed and covered with paint. Usually used for exterior decoration of buildings without a ventilated facade.

Vinyl siding- these are polyvinyl chloride one and a half millimeter panels with a length of 3.66 meters to 3.85 meters and a width of twenty to twenty-eight centimeters. Sidings are produced with imitation of one, two or three boards. And therefore they are called, respectively, single, double or triple. The outer side can be made as natural wood or painted in a single color.

Vinyl panels are resistant to ultraviolet, dyes. They do not absorb moisture, do not rot, do not mold. Elastic, resilient, resistant to mechanical stress, impact resistant. Are not toxic. TO vinyl siding accessories for corners, ceilings, cornices, windows and others are included with the sale.

Insulation of walls outside with mineral wool for siding

Mineral wool is great option insulation of walls of buildings of any type. These works can be done with their own hands and the owner of an individual house without the help of professionals.

Wall insulation works with mineral wool include the following steps. First, the entire surface of the walls is cleaned. Antiseptic works are being carried out. If the walls are wooden, then the surface is treated with a refractory primer.

Lathing in progress from metal profiles or wooden bars. The crate is fixed to the wall with dowels. Attached near doors and windows additional elements crates. The step of profiles or bars usually does not exceed sixty centimeters. Mineral wool slabs should fit very tightly into the crate.

A hydro-windproof membrane is applied over the heat insulator. For the device of a gap for ventilation, the membrane is fastened with a counter-lattice of bars three centimeters thick. Siding panels are mounted on them.

Insulation of walls outside with foam

Operations for wall insulation from the outside with foam plastic with siding can be performed in any season. If vinyl siding is used, then the air temperature must be at least minus ten degrees.

For installation of thermal insulation on the walls of the building under the siding you will need the following tool:

• Grinding machine ("Bulgarian") with a disc of at least 150 mm.
• Perforator-drill.
• Scissors for cutting metal.
• Jigsaw, preferably electric. A set of saws for wood and metal.
• Screwdriver.
• Screwdriver, hammer.

After preparing the walls, the crate is mounted. Desirable for foam wooden crate. First you need to decide on the location of the siding itself: vertically or horizontally. This is necessary to establish the step between the bars. The thickness of the bar depends on the foam. The tree is treated with a refractory and antiseptic composition.

The walls are treated with water-repellent mastic, but you can not use products that clog the movement of steam and air. When the walls do not let air through, the room will become a thermos.

Additional frame elements are installed around window and door openings.

The batten is fixed to the walls with special dowels. After the installation of the crate is completed, insulation is inserted into the openings between the bars and fastened with special dish-shaped screws. The joints between the sheets are foaming mounting foam. This ensures the seamlessness of the insulation.

After laying the foam windproof membrane attached, which must pass moisture and air from the building to the street. She also removes steam from the heater. It should be borne in mind that this membrane is a highly combustible material. You can not stretch it over the foam. A counter-lattice is arranged from bars 2-3 centimeters thick. Siding is mounted on top of the counter-lattice.

Insulation for brick walls

Brick is not combustible and durable. This is a material that can withstand high loads. The main disadvantage is high thermal conductivity. Therefore, in some cases, the walls of houses must be insulated.

What is the best insulation for the walls of a brick house? Any. Extruded polystyrene foam, polystyrene foam, mineral wool, warm plaster. Only they need to sheathe the walls in different ways. So, foam can be glued to a brick. And for the installation of mineral wool, you need to arrange a crate and a ventilation gap.

Conclusion

If the wall of the house does not provide reliable heat retention, then it is necessary to insulate your house. What to sheathe and in what volume is the choice of the homeowner.

Siding has a lot of positive characteristics, but it cannot boast of thermal insulation properties. That is why, when finishing residential buildings, the walls are first insulated, and only then the coating panels are attached. What kind of insulation under siding has the best properties, by what criteria it is necessary to choose it, and how to properly perform the insulation with your own hands - this will be discussed in the article.

In every hardware store heaters are presented in a wide range, and it is very difficult for an inexperienced person to understand them. Rolled and slab, expensive and cheap, domestic and foreign production, of different density and thickness - how to determine exactly what you need?

First of all, you need to be guided by the requirements that the material must meet:

• low thermal conductivity is one of the most important qualities that a heater should have. The lower this indicator, the less heat comes out through the walls of the room;
• resistance to temperature extremes and moisture - since the insulation is located on the outside of the building, it is exposed to high and low temperatures, and not all materials retain their original properties. When moistened, the same thing happens, in addition, the risk of fungus under the skin increases;
• environmental friendliness - the presence of toxic compounds in the composition poses a health hazard and requires additional protective measures when performing thermal insulation;
• fire safety - insulation should not contribute to the spread of fire during a fire and emit toxic smoke during combustion. Therefore, preference should be given to fire-resistant and self-extinguishing materials;
• durability - this implies that the insulation must fully retain its characteristics, including geometric shapes, throughout the entire period of operation. Unfortunately, many materials shrink after a few years, or begin to crumble, which leads to a decrease in thermal insulation properties.

Not all materials possess such qualities in full, and below we will consider only the most suitable ones. Next, you need to take into account the method of installation, especially if you are going to do all the work yourself. Rolled heaters are less convenient in installation, it is much easier to fix the plates.

Roll and slab heaters

Types of heaters

The most popular heaters for siding today are:

• mineral wool;
• based on expanded polystyrene;
• blown heaters (ecowool, penoizol, polyurethane foam).

Mineral wool, according to GOST 52953-2008, is divided into three types - stone, slag and glass wool.

GOST R 52953-2008 - free download. MATERIALS AND PRODUCTS HEAT-INSULATING

For the production of the first type, basalt and silicate rocks, as well as their mixtures, are used, slag wool is made from metallurgical waste, glass wool is made from glass industry waste. These insulations are very thin fibers pressed into sheets of great thickness, which are available in the form of rolls and mats of various sizes and densities. Additionally, they can be coated with foil. As a rule, only stone and glass wool is used to insulate a house under siding, since slag insulation has less water resistance.

Mineral wool insulation with a foil layer

Expanded polystyrene insulation, polystyrene foam and EPS, are lightweight dense sheets formed from a large number of closed cells filled with air. Due to this structure, these heaters practically do not absorb water. They are produced only in the form of plates that differ in density, size, degree of flammability.

Blown materials are those materials that are applied to the base using special installation under high pressure. After drying, they form a durable seamless coating with excellent thermal insulation properties.

Blowing insulation - ecowool

Characteristics of mineral wool insulation

stone wool

Of all the varieties of stone wool, basalt insulation is considered the most popular. It has the lowest content of binding components, which include formaldehyde resins and phenol hazardous to health, which means it is one of the most environmentally friendly materials. The fibers that make up the insulation are not prickly and smooth enough, so they do not cling to clothes, do not cause skin irritation, and work can be done without protective gloves.

Options	Values
Thermal conductivity	0.035-0.041 W/(m K)
Water absorption	no more than 2%
Vapor permeability	0.55 mg/MhPa
Density	30-225 kg/m3
Working temperature	from -180 to 700 ᵒС
Degree of combustibility	non combustible material
Material thickness	from 30 to 150 mm
Dimensions	500x1000 mm, 600x1000 mm, 600x1200 mm

Manufacturers produce stone wool in the form of mats, soft, semi-rigid and rigid slabs, in rolls. For installation under siding, rigid and semi-rigid boards are the most convenient, but roll insulation is more suitable for horizontal and inclined surfaces.

Advantages of stone wool:

• the material is easy to cut, has a small weight, does not create difficulties during installation;
• does not burn or emit harmful substances;
• it does not develop microorganisms, including fungi;
• reduces noise level up to 20%;
• the service life is 40-50 years without loss of basic characteristics.

• the production of the material requires high costs, respectively, the prices for stone wool are quite high;
• when cutting and shaking the material, the fine fibers break and form a very fine dust, which easily enters the respiratory tract. As a result, during thermal insulation works always use a respirator.

There are many manufacturers who, in order to reduce the cost of the manufacturing process, use various industrial wastes instead of pure rocks, but at the same time pass off their products as high-quality basalt insulation. Visually recognizing a fake is very difficult, especially for an inexperienced person, so buy stone wool from well-known, time-tested brands. Now the following manufacturers enjoy a high reputation in the market of thermal insulation materials:

The popularity of glass wool has fallen markedly with the advent of basalt and slag insulation on the market, but it is still used in various fields. In appearance, it does not differ much from stone wool, but it is more brittle, so many manufacturers additionally reinforce the material by piercing with steel threads. A feature of glass wool is that the glass fibers are destroyed at the slightest impact and form a fine dust that easily eats into the skin, penetrates the respiratory tract, eyes and causes severe irritation. For this reason, you can work with glass wool only in protective clothing, a respirator and goggles.

Specifications

Options	Values
Thermal conductivity	0.039-0.047 W/(m K)
Vapor permeability	0.6 mg/mh*Pa
Water absorption	1,5-1,7%

Degree of combustibility	from NG to G1
Material thickness	50-100 mm
Dimensions	610x1170 mm, 600x1250 mm
Working temperature	from -60 to 450 ᵒС

Advantages of glass wool:

• Due to its low thermal conductivity, glass wool perfectly retains heat in the house. A layer of material 50 mm thick is similar in terms of thermal insulation properties to meter-thick brickwork;
• no toxic additives are used in the manufacture of glass wool, so it does not emit harmful substances even under the influence of high temperatures;
• glass wool boards are light in weight and can be compressed in the package by 6 times their original volume, followed by straightening, which simplifies the transportation of insulation;
• the material is easily cut and mounted on the walls;
• microorganisms do not develop in glass wool and insects and rodents do not start;
• Compared to other fiber insulation, glass wool is much cheaper.

• high fragility of the fibers requires enhanced protection and caution in work, increased loads on the material should be avoided;
• the average life of glass wool is 10 years, then it shrinks heavily and does not provide even minimal thermal insulation of the walls;
• glass wool absorbs wet vapors and water, which leads to a complete loss of thermal insulation characteristics.

Advice. Slabs laminated with fiberglass and with a density of about 30 kg / m3 are best suited for siding. In order not to get low-quality insulation, pay attention only to certified glass wool from leading manufacturers, for example, Knauf, Isover, Ursa, the domestic brand Neman.

Mineral wool

Characteristics of polystyrene foam insulation

Polyfoam has a very low hygroscopicity, which is much superior to fibrous insulation. Walls sheathed with foam plastic also do not require additional wind protection. This is one of the most budget options insulation, although not the most effective. Due to the vapor impermeability of the material, it is necessary to regularly ventilate the room so that condensation does not accumulate on the walls.

Pros of foam:

• affordable cost;
• low thermal conductivity;
• light weight;
• ease of installation.

• in terms of noise absorption, foam is inferior to other types of heaters;
• sheets of material break easily, so care must be taken during transportation and installation;
• polystyrene is damaged by rodents;
• refers to combustible materials, emits toxic fumes when burned.

EPS (extruded polystyrene foam)

This material has characteristics similar to polystyrene, but in all respects it is much better. XPS is widely used in industrial and private construction, its installation does not require much effort or special skills.

• high density and strength of the material;
• almost zero hygroscopicity;
• excellent thermal insulation properties;
• good indicators of noise absorption;
• long service life;
• relatively low weight.

• the cost of XPS is about 20-30% higher than that of polystyrene;
• does not allow the walls to "breathe";
• can be damaged by rodents;
• refers to combustible materials.

Characteristics of blown heaters

Ecowool is a new material made from cellulose fibers. It contains a binder - lignin, flame retardants and boric acid as an antiseptic. Ecowool is a loose mass, which is applied dry or "wet" method.

Penoizol and polyurethane foam have a cellular structure and are applied to the walls in liquid form. They are light in weight, so they almost do not exert loads on the base, but at the same time cover the entire area with a dense, uniform layer. With this method of insulation, there is no need to level the walls and install wind protection, which greatly simplifies installation.

• lack of cold bridges;
• durability;
• low thermal conductivity;
• installation speed.

• these materials are more expensive than other heaters;
• for application, it is necessary to have special expensive equipment and experience with it.

Siding insulation installation

Regardless of the material chosen and how it is attached, you first need to properly prepare the surface. To do this, they remove everything that can interfere with work - lighting devices, platbands, decorative elements and other items, and then carefully inspect the walls. It is not necessary to level the base, but it is necessary to repair the cracks and remove the fungus.

As a crate for siding, use a wooden beam or metal profiles. If you prefer timber, you should pre-treat it with an antiseptic impregnation to avoid damage to the wood from condensation and mold development.

Prices for different types of bars

Wall insulation with mineral wool

Step 1. A frame made of timber with a section of 50x50 mm is fixed on the wall. The bars are fastened vertically with self-tapping screws and dowels, the distance between the posts should be 1.5-2 cm less than the width of the insulation. Be sure to control the vertical position of the racks building level so that all elements of the crate are in the same plane.

Step 2 Slabs of mineral wool are alternately inserted between the bars, slightly crushing the edges. After installation, the material is easily straightened and densely fills the cells of the crate. If necessary, the plates are cut with a knife or a fine-toothed hacksaw.

Step 3 If the insulation is planned to be mounted in two layers, horizontal jumpers from a bar are fixed on top of the racks with self-tapping screws at the same distance. Next, the mineral wool slabs are fixed again.

Step 4 A windproof membrane is attached over the insulation. Since its width is not enough for the entire area of ​​\u200b\u200bthe wall, it is fixed with horizontal stripes, starting from the bottom of the facade. It is most convenient to use a stapler to fix the membrane. Each subsequent strip is laid with an overlap of at least 10 cm. To increase the tightness of the coating, the joints are glued with adhesive tape along the entire length.

Step 5 Next, strictly according to the level, guides for siding are installed using mounting plates. The plates are fixed with self-tapping screws to the crate in increments of 40 cm. An air gap of about 3-5 cm should remain between the guides and the windproof membrane.

After that, proceed to the cladding of the facade with siding panels. As you can see, the technology is quite simple and everyone can do it. The most important thing is to firmly fix the plates so that they do not hang between the racks. If there are gaps, the heat will go out and all efforts will be in vain.

Siding prices

Insulation with extruded polystyrene foam

Step 1. On the wall, mark the location of the suspensions for the guides according to the level. Hangers should be fastened along the entire facade in increments of 40 cm. Holes are drilled at the marked points, dowels are inserted and the hangers are fixed with screws.

Step 2 They take an EPPS plate, apply it to the wall and press it a little so that traces of the suspensions are imprinted. On these tracks, cuts are made in the insulation with a knife or a special cutter. Next, the plate is again attached to the wall and put on suspensions, pressing tightly to the base.

Step 3. The remaining plates are fixed in the same way, trying to make the joints as thin as possible. If gaps have formed in some places during work, they must be sealed with mounting foam using a gun.

Step 4 After sheathing the facade with insulation, they begin to install guide profiles for siding. The profiles are attached to suspensions that protrude from the heat-insulating layer, a ventilation gap of 2-3 cm wide is left between the guides and the insulation. Next, the siding is attached.

This insulation can also be attached with dowels-umbrellas and special glue. In this case, it is more convenient to first mount the crate to which the siding will be attached. Glue is applied to the insulation, then the plate is inserted between the guides and pressed against the base. Upon completion of the installation, the plates at the joints are additionally fixed with dowels-umbrellas.

Ecowool insulation

Wall insulation with ecowool can be done in two ways - dry and wet. The first method is not reliable enough, since the material is blown through small holes in protective film, and it is impossible to control the density and uniformity of filling. In this regard, the wet method is more convenient, the whole process takes place in plain sight. It is this second method that we will consider.

Step 1. The walls are cleaned of dust, cracks and other defects are eliminated. Strictly level guides for siding will be strengthened in increments of about 50 cm. The guides must be fastened using mounting plates so that the frame thickness is at least 10 cm.

Step 2 Ecowool is poured into a blowing machine, a water-gel solution is added there, mixed until smooth.

Step 3 Turn on the installation and apply a viscous mass to the walls in a dense layer. Joints and corners are especially carefully processed so that there are no voids.

Step 4 Allow the insulation to dry completely, after which the siding panels are mounted to the crate.

In a similar way, the house is insulated with penoizol and polyurethane foam. Many companies rent spraying equipment, which is much cheaper than buying equipment. But in order to do everything qualitatively, certain skills are needed, and it is better for a beginner to hire specialists for this.

Video - Installation of EPPS insulation under siding

Siding is a good protection for any thermal insulator. Therefore, finishing with foam plastic, followed by cladding with vinyl panels, is very advisable. Insulation of a building from the outside can be attributed to one of the main stages in the construction of any house, since without additional protection, wood, brick and even reinforced concrete will gradually collapse under the influence of harmful environmental factors. The use of siding can qualitatively extend the life of load-bearing walls of any design.

A little about foam

Installation of expanded polystyrene boards under siding is a cost-effective solution for creating an optimal thermal insulation layer. In addition, the material has good sound insulation characteristics, is environmentally friendly and does not burn.

Despite the fact that expanded polystyrene is not combustible, it melts under the influence of high temperatures or open fire. At the same time, combustion products are released into the atmosphere, which, if they enter the respiratory system of a person, can cause injuries incompatible with life.
Currently, two types of polystyrene foam boards are used in individual construction, any of them can be used to insulate your own house from the outside, followed by finishing for siding:

• Ordinary foam;
• extruded.

The table shows the average values ​​of the coefficients of materials, depending on the manufacturer, they may differ slightly from those indicated.

Mounting technology

The shape and structure of both types is similar, so the principle will be the same for both insulation from the outside with polystyrene foam and foam. Before you start warming the facade, you need to treat it with an antiseptic. This will prevent the formation of mold and the appearance of insects in the walls that destroy the supporting structure.

Lathing plane definition

The next step will be marking the plane of the walls and determining the location of the guides (this can be a wooden bar with a size of at least 20x30 mm or a galvanized profile 60x27 mm). Since the exterior cladding is made using siding (which is usually installed in a horizontal position), the guides must be mounted vertically.

An exception is metal siding or block house. Its installation can be carried out both horizontally and vertically in relation to the ground.

Vertical plumb lines are hung at the corners of one wall, with the help of which the location of the two extreme guides is determined. Then two ropes, fishing lines are pulled between them (top and bottom). It is for them that the subsequent installation of the remaining elements of the crate is carried out.

useful at work

Some manufacturers of plastic exterior wall siding offer vertical panels to their customers. Their installation is carried out on a horizontal subfacing system.

Mounting rails

Insulation of the walls of a residential building, followed by finishing for siding, is carried out with a step between the guides of at least 40 cm. Fixation is carried out using galvanized brackets or (if a wooden beam is used) with self-tapping screws.

Despite the fact that the construction of a metal sub-facing system is more expensive from the outside than the installation of an analogue made of wood, the service life of the former is much longer. Therefore, the right to choose which material to use for this remains with the owner of the house.

useful at work

When installing the crate from a wooden beam, you need to make sure that the wood is dry. In addition, work in damp rainy weather can lead to swelling of the structure and subsequent drying and warping.

Installation of thermal insulation

As mentioned earlier, the characteristics of polystyrene foam and polystyrene foam are almost identical, so the fixing method is described alone. Wall insulation with plates is recommended to start from the bottom row and gradually rise. First of all, whole sheets are laid, small openings are closed afterwards.

To ensure better fixation, the foam with the help of fungi - umbrellas is attached to the wall of the house. It is desirable to attach plates in each corner and at least one anchor should hold the insulation in the center. It is allowed to place anchor elements in the seams of the material, thereby “pressing” two sheets of thermal insulation to the facade at the same time.

If the climatic conditions of the region in which the house is located require that the insulation be carried out in two or three layers, the imposition of one seam on another is not allowed. This can lead to the formation of cold bridges and the gradual wetting, freezing and destruction of the walls.

Insulation of the house with polystyrene foam followed by cladding with siding is one of the most economical and practical options for exterior decoration of buildings made from any building materials. The method is actively used both in the construction of new facilities, and for the decoration and reconstruction of already built ones.

must be taken into account during installation. That all window and door openings will be slightly pressed into the walls. Thus, for their subsequent finishing, additional materials will be required, which are best purchased in advance.

Plastic (vinyl or acrylic) siding is mounted only with strict observance of technological requirements when working with the material:

• Work on finishing the exterior walls of the house is allowed only at an ambient temperature of at least 10 degrees above 0. In the cold, the panels lose their flexibility and may crack as a result of installation;
• Fasteners that fix the siding must be made of stainless steel or have a galvanized coating;
• Self-tapping screws are not wrapped all the way, this is done so that the panels can slightly shift under the influence of temperature changes (in the cold, the siding decreases in size by 1-2 cm, when heated, on the contrary, it increases);
• Screws are screwed only at a right angle of 90 degrees.

Only by observing all the necessary requirements, you can create a high-quality and durable facade that can not only improve the characteristics of the walls, but also modify the whole house.

House insulation is considered topical issue for latitudes with a continental climate. In addition to mineral wool and polystyrene, there are new generation heaters that are used by developers.

It is no secret that it is extremely economical and quite simple to carry out self-insulation of walls from the outside with foam plastic with siding sheathing. This is because it becomes possible to use plates with a smaller material thickness.

That is why, given material Perfectly is suitable for external and internal warming of a building. EPPS insulation is obtained by means of a press, so the density of this insulation is much higher than the foam.

What is siding and why is it needed for sheathing? Siding is called the exterior wall cladding of a building, which performs several functions:

1. Protects the building from outside influences, as well as precipitation and other weather conditions;
2. The aesthetic component is the representative decor of the front side of the building.

To insulate an old house and give it modern look outside, there is nothing easier than foam and siding. Both of these materials are easy to install and can last up to 50 years. Wall insulation from the outside or foam for siding is a fairly well-known method, although it cannot be called economical. Extruded polystyrene foam is not the cheapest of heaters, but this is more than offset by its heat-insulating properties.

Before diving into reading the material of this article, we suggest that in our other material we familiarize ourselves with information about finishing the facade insulated with expanded polystyrene. Surely this will be a useful addition. Deciding to hold modern insulation penoplex, it is worth remembering a few things:

• Extruded polystyrene foam with conventional wall insulation is only suitable for the lower tier of the house, the basement;
• If you intend to use it on higher tiers, the structure must be ventilated, and it must be not just foam under the siding, but facade slabs;
• For private, cottage housing construction, it is usually used vinyl siding, for finishing multi-storey buildings insulation under metal siding is included in the system of hinged facades in the form of facade slabs;
• The foam plastic assembly technology for cladding does not require reinforcement, in contrast to cases when plaster is used as a finish;
• Extruded polystyrene foam does not conflict with concrete and aerated concrete, silicate and clay bricks. It is possible to insulate the walls with foam plastic, taking into account the siding in wooden houses, but you need to act very carefully, since the tree is extremely distrustful of modern heaters.

Stages of house insulation with foam for siding

The technology of insulation and finishing of the basement provides for the calculation of the thermal resistance of the walls of the house and the determination of how thick the thermal insulation layer is needed. For external wall insulation, it makes no sense to take material thinner than 4-5 cm, since this is not economically viable. In this case, it is better to use a different type of thermal insulation, or do without it altogether, mounting the siding directly on the facade. The necessary heat can be obtained through interior decoration. All stages can be divided into two parts - installation of insulation and installation of siding. These works are carried out according to the rules provided by the technology for each of the materials.

First, you need to decide how you need to mount the penoplex with siding cladding. For example, it can be attached to the walls with adhesive for thermal insulation or fixed to a pre-installed crate. Glue is usually used on the base. Additionally, heat-insulating plates are fixed to the wall with plastic fasteners-fungi. Arrange them as regularly as possible, in rows.

Siding installation sequence

Many are interested in the question of how to fix the siding on penoplex and where exactly to start? First, you need to make a crate of wooden slats, or a special metal profile. It is mounted through the insulation to the wall using dowel-nails or long self-tapping screws. It is necessary to make sure that the slats are fixed securely and at the same time do not crush the thermal insulation. During installation, they can be supported on the caps of fungi, which we “lined up” in rows for this. Another way is to fix the brackets on the wall in advance, while gluing the foam, for which the planks will then hold. Installation of siding on penoplex should be carried out with a gap of at least 2 cm, which means that this should be the minimum thickness of the crate. Sheathing with foam siding is carried out according to the technology provided for the installation of siding using starting and finishing strips, corners and other elements.

Once again, we note such a moment - the insulation of the house with foam plastic for siding requires accurate calculations of the thermal insulation layer. If you take this lightly, the “dew point” - the condensation point of moisture in the wall - may shift. Then dampness will inevitably appear in the house.

Whether or not to use penoplex for insulation is a master's business. Some are inclined to this option because of the relatively simple installation, while others, on the contrary, believe that foam plastic has no place in the insulation of the house above the foundation. Having studied everything available materials, asking the opinion of professionals, everyone will make their own choice.

Insulation of brick walls from the outside with polystyrene foam

High-quality insulation of a brick house outside with polystyrene foam for siding is not a simple process and requires special knowledge and skills.

Brick buildings are famous for their long service life and endurance, but this building material There is a significant drawback - high thermal conductivity. That is why brick houses need professional insulation and finishing. To begin with, specialists perform a heat engineering calculation, which consists in calculating the required design resistance for the walls of a building. This feature will help to proper insulation walls of a brick house, not only outside, but also inside.

Some experts recommend insulating the facade of houses with extruded polystyrene foam, since this material is deservedly considered the best outdoor type insulation in regions with harsh weather conditions and high content moisture in the air. We are talking about areas with a maritime climate. In more stable regions, it is quite enough to carry out the installation of foam for siding on the walls of structures.

There is an opinion that polystyrene foam and penoplex are functionally almost eternal, but is it so? This judgment is indeed justified, since the features of the molecular structure of these materials are such that they heroically endure the effects of air, solar radiation, moisture, light, etc. It is worth considering that due to excessive and constant exposure, for example, to sunlight on the finish, it will lose its thermal insulation properties. Wall insulation is able to withstand about 50 cycles of freezing and thawing under the cladding.

Installation of these heat-insulating materials outside and inside, as already mentioned above, needs a professional hand. To the number additional features wall insulation include:

• Light weight and easy installation;
• Ease of installation of the crate on the material and the final cladding;
• Increased resistance to compression;
• Ease of transportation, additional processing (laying, cutting), as well as storage;
• Air permeability of XPS and impermeability of foam.

If you make a choice in the direction of the external insulation of the walls of a residential building, then a clear victory will go to expanded polystyrene as a material that breathes and simply fastens. In this case, the need for expensive vapor barrier inside the house simply disappears. The room will receive additional comfort thanks to breathing walls, despite the cladding, and savings.

Wall insulation from the outside with foam cladding with siding

One of the easiest ways to increase the heat resistance of any home is to insulate the walls on the outside with foam plastic, followed by siding. Extruded polystyrene foam (EPS) is an excellent high-performance thermal insulator, and siding protects it from ultraviolet radiation.

However, this procedure is not applicable for all wall materials. For some materials, it is impossible to insulate the walls from the outside with foam plastic with siding sheathing.

Why? Let's look at this issue in detail.

Which houses can be insulated from the outside with EPPS

So, when is it possible to insulate a house from the outside with foam plastic for siding? Then, when the wall material, which is used for the construction of the building, has a low vapor permeability.

In this case, the extruded polystyrene foam will not lock the moisture that is formed when water vapor escapes from the living quarters inside the wall.

For example, let's take concrete wall. Concrete has almost zero vapor permeability. And between concrete wall and a layer of extruded polystyrene foam will not condense water vapor.

This rule will be true for all heavy concretes. For example, for expanded clay concrete, from which blocks are made for private construction.

But if light concretes with good vapor permeability are used, such as foam concrete or aerated concrete, foam plastic cannot be used for their insulation. The insulation for the walls of the house outside under the siding for such walls should be with a vapor permeability not lower than that of the wall material.

For insulation of foam concrete and aerated concrete, ordinary expanded polystyrene - PSB or PSB-S is perfect. The lower the density of expanded polystyrene, the better its vapor permeability will be.

eps and wood

Separate "relationships" for extruded polystyrene foam with wooden walls.

If you want to wooden walls"breathed", then for this option you will need another insulation for the walls of the house outside under the siding. Penoplex is simply a ban on the exit of water vapor - the wooden wall will rot, and as a result, the walls of the house will become unusable.

To prevent this from happening, interior spaces wooden walls are sheathed with vapor barrier - a film that does not let water vapor through, leaving it in the room.

In this case, water vapor does not enter the wall and, as a result, there is nothing to condense between the wall and the layer of vapor-tight insulation.

For the same reason, it is possible to use XPS as a heater in frame house, because from the inside the frame is sheathed with a vapor barrier with an overlap and sizing of the seams.

However, in this situation, there are two important additions to a wooden house:

1. Since now the wooden walls do not allow water vapor to pass through, the correct exhaust ventilation, which would remove this steam from the interior to the street.
2. By mounting the vapor barrier from the inside onto wooden walls, you actually turn your house into a "thermos". Are you sure this is what you want?

As for the timber, the timber is also a tree. I think that after reading this section, you yourself can now tell how to properly insulate a house from a bar from the outside with foam plastic for siding.

The process of insulation with extruded polystyrene foam under the siding

If you want to insulate the house from the outside with foam plastic with your own hands under the siding, then you need to know three simple things:

1. When insulating an EPPS wall made of brick, foam concrete, aerated concrete, porous blocks or warm ceramics, you must isolate the wall from the inside from water vapor.
2. When you insulate with polystyrene foam over a wooden or steel frame, it is better to foam the seams between the insulation and the frame, since XPS is a completely inelastic material and will not close the seams, like cotton wool, for example.
3. It is not necessary to make wind protection or vapor barrier to protect the insulation, since the XPS is not blown at all, does not crumble and does not crumble. But it is necessary to close it from ultraviolet radiation, since it begins to decompose in the sun.

Here, in general, and all the features of the use of this wonderful insulation under decorative trim vinyl facade panels.

How to sheathe insulation for the walls of a house outside under siding, mineral wool or penoplex

At some point, the owner of a private house realizes that the walls of his house do not cope with the task of retaining heat. This problem can only be solved by insulating the walls from the outside. At the same time, the wall of the house itself will be protected from moisture and direct sunlight.

Options for insulating the outer walls of buildings and the properties of the insulation

There are several options for organizing the external insulation of the walls of the house:

• The insulation is glued to the wall with a special adhesive. From above, the surface is covered with a layer of plaster.
• The insulation is glued to the wall. Then, observing a small gap, the wall is laid in one brick. This is one of the types of ventilated facade.
• Ventilated facade. Waterproofing is installed on the wall. A heater is arranged on top of it, and a hydro-wind protection is placed on it. On top of all this "pie" is mounted external cladding, that is, siding. These works can be carried out at any time of the year.

All types of modern wall insulation materials have their own characteristics. They differ from each other not only in the coefficient of thermal conductivity, but also in price. And the consumer pays attention to the following insulation features:

Given the characteristics of the insulation available to the owner of the house, the method of mounting it on the wall of the house is also selected.

The main types of wall insulation

Nowadays, as the main insulation for the walls of the house outside under the siding the following materials are used:

• Polyfoam (expanded polystyrene), foam plastic, polyurethane foam.
• Mineral wool.
• Basalt insulation.

The thermal conductivity of each insulation material can be visualized using the following comparative table. As a starting material for comparison, a standard brickwork 90 centimeters thick is taken.

Styrofoam (expanded polystyrene)

This is a modern insulation for walls and other surfaces.. It is used in all areas of industrial and civil construction. It has a low coefficient of thermal conductivity. Resistant to chemical and biological influences, has high sound insulation. Durable and environmentally friendly material with a service life of more than fifty years.

Another advantage of foam sheets is their light weight and low price. Weight contributes to the low labor intensity of the work performed, does not load the walls, which eliminates the need for additional strengthening of the foundation. The disadvantage of this material is flammability.

Extruded polystyrene foam (foam)

Thermal insulation material of the latest generation based on graphite nanoparticles. Foam thermal conductivity coefficient is 0.03 W/m*K. Very resistant to mould, chemicals, insects and rodents. Excellent sound insulator. In addition to insulating the walls of buildings, it is used in the manufacture of the foundation of individual low-rise buildings using the “insulated Swedish plate” technology. It is used for protective sheathing of loggias and balconies, basement walls.

polyurethane foam

Plastic with foam-cell structure. The proportion of air-filled cells in polyurethane foam reaches 90 percent of the total mass of the insulation. Because of this, its thermal conductivity is one of the lowest. Differs in good adhesion with all materials of surfaces: wood, concrete, metal and brick.

Thanks to this, an airtight coating with good hydrovapor barrier is created.

It is applied to the surface under pressure using a hose and a compressor. The plastic mass during blowing fills all cavities and cracks. The disadvantage of this insulating material is the high cost and the need for expensive equipment.

Mineral wool

This is a basalt insulation, glass wool, stone wool. A product of the processing of metallurgy waste and the processing of rocks such as dolomite and basalt. Differs in durability incombustibility, environmental friendliness, durability, elasticity. Low price and ease of installation. Absorbs sound well. You can install cotton wool at any time of the year. When insulating walls from the outside with mineral wool for siding, it does not require special skill.

The industry produces this insulation in rolls and in the form of plates. Rolled insulation is used to cover horizontal surfaces or surfaces with a slight slope. It is more convenient to insulate vertical walls with slabs. Mineral wool can be used in conjunction with blown polyurethane foam. Rolls and slabs are produced in the following sizes:

Liquid thermal insulation

These are new generation heaters.. Liquid heat-insulating materials are now insulated with metal pipes, foam block houses and other structures. It is a multi-component ceramic substance similar to acrylic paint. It only contains up to 80 percent of voids in its sticky mass.

It is applied to the surface to be insulated with an ordinary paint brush, roller or spray gun. When applied with a spray gun, it fills all the cracks and voids. After drying (at least six hours), it is resistant to mechanical stress, protects structures from precipitation and the sun, metal from corrosion.

Siding, its characteristics and types

They call it siding thin (from one to ten millimeters) type-setting panel parts for facing the facades of buildings and other structures with a length of two to six meters. The width of the siding is from ten to thirty centimeters. This is not only a decorative coating. In many cases, siding panels are an important part of a multi-layer insulated wall covering. And they are also mounted to improve the hydrothermal insulation of the entire structure, to protect against external noise.

Sidings are vinyl, wood, metal and cement. Metal panels are made of steel and aluminum with a width of twelve centimeters to fifty-five centimeters. The surface is made perforated or without holes. Figured or smooth-smooth. Currently, wide smooth sidings are in demand. They are universal. They are mounted both vertically and horizontally. Metal siding is much more durable than vinyl siding, it is fireproof and requires no special maintenance. It is little affected by changes in ambient temperature.

wood siding are made by pressing wood fibers and binders under high temperature. During manufacture, paint is applied to the panel at high temperature at five. The paint creates a reliable protection. For environmental reasons, resins containing phenol-formaldehyde substances are not used in the production of wood panels. In appearance, they are much more attractive than other species.

Cement siding panels made from cement mortar with the addition of cellulose. The surface is primed and covered with paint. Usually used for exterior decoration of buildings without a ventilated facade.

Vinyl siding- these are polyvinyl chloride one and a half millimeter panels with a length of 3.66 meters to 3.85 meters and a width of twenty to twenty-eight centimeters. Sidings are produced with imitation of one, two or three boards. And therefore they are called, respectively, single, double or triple. The outer side can be made as natural wood or painted in a single color.

Vinyl panels are resistant to ultraviolet, dyes. They do not absorb moisture, do not rot, do not mold. Elastic, resilient, resistant to mechanical stress, impact resistant. Are not toxic. Accessories for corners, ceilings, cornices, windows and others are included with vinyl siding.

Insulation of walls outside with mineral wool for siding

Mineral wool is an excellent option for wall insulation of buildings of any type. These works can be done with their own hands and the owner of an individual house without the help of professionals.

Wall insulation works with mineral wool include the following steps. First, the entire surface of the walls is cleaned. Antiseptic works are being carried out. If the walls are wooden, then the surface is treated with a refractory primer.

Lathing in progress from metal profiles or wooden bars. The crate is fixed to the wall with dowels. Additional elements of the crate are attached near the doors and windows. The step of profiles or bars usually does not exceed sixty centimeters. Mineral wool slabs should fit very tightly into the crate.

A hydro-windproof membrane is applied over the heat insulator. For the device of a gap for ventilation, the membrane is fastened with a counter-lattice of bars three centimeters thick. Siding panels are mounted on them.

Insulation of walls outside with foam

Operations for wall insulation from the outside with foam plastic with siding can be performed in any season. If vinyl siding is used, then the air temperature must be at least minus ten degrees.

For installation of thermal insulation on the walls of the building under the siding you will need the following tool:

• Grinding machine ("Bulgarian") with a disc of at least 150 mm.
• Perforator-drill.
• Scissors for cutting metal.
• Jigsaw, preferably electric. A set of saws for wood and metal.
• Screwdriver.
• Screwdriver, hammer.

After preparing the walls, the crate is mounted. For polystyrene, a wooden crate is desirable. First you need to decide on the location of the siding itself: vertically or horizontally. This is necessary to establish the step between the bars. The thickness of the bar depends on the foam. The tree is treated with a refractory and antiseptic composition.

The walls are treated with water-repellent mastic, but you can not use products that clog the movement of steam and air. When the walls do not let air through, the room will become a thermos.

Additional frame elements are installed around window and door openings.

The batten is fixed to the walls with special dowels. After the installation of the crate is completed, insulation is inserted into the openings between the bars and fastened with special dish-shaped screws. The joints between the sheets are foamed with mounting foam. This ensures the seamlessness of the insulation.

After laying the foam windproof membrane attached, which must pass moisture and air from the building to the street. She also removes steam from the heater. It should be borne in mind that this membrane is a highly combustible material. You can not stretch it over the foam. A counter-lattice is arranged from bars 2-3 centimeters thick. Siding is mounted on top of the counter-lattice.

Insulation for brick walls

Brick is not combustible and durable. This is a material that can withstand high loads. The main disadvantage is high thermal conductivity. Therefore, in some cases, the walls of houses must be insulated.

What is the best insulation for the walls of a brick house? Any. Extruded polystyrene foam, polystyrene foam, mineral wool, warm plaster. Only they need to sheathe the walls in different ways. So, foam can be glued to a brick. And for the installation of mineral wool, you need to arrange a crate and a ventilation gap.

Conclusion

If the wall of the house does not provide reliable heat retention, then it is necessary to insulate your house. What to sheathe and in what volume is the choice of the homeowner.

How is the installation of siding on penoplex

Penoplex in installation is used quite often Penoplex (extruded polystyrene foam) is a modern synthetic material suitable for thermal insulation work. Penoplex as a heater and insulating material for siding is used quite often, which is explained by its advantages and improved quality characteristics.

Benefits of penoplex

To date, for thermal insulation produced a large number of variety of materials and penoplex is one of the most effective and modern. It belongs to the category of environmentally friendly materials and is completely not subject to such processes as rotting and decomposition under the negative influence of precipitation.

The material is very durable and has excellent sound and heat insulation characteristics. In addition, penoplex is quite affordable, and is also quite easy and quick to install on its own, without the involvement of specialists.

The advantages of penoplex include also low vapor permeability, good fire safety, flexural and compressive strength, no deformation and destruction under prolonged exposure to high and low temperatures.

Penoplex is a modern synthetic material suitable for thermal insulation work.

Compared to foam, this insulation has more high level rigidity and increased strength. Penoplex is produced as plates of various sizes and thicknesses, which facilitates the work on the insulation of facades. The average service life of such material is more than fifty years. The base for penoplex must be dry, even and clean.

Features of siding installation

Installation work on the cladding of the facade of the building with siding panels over the foam can be performed only after the insulation layer is properly fixed to the base. When working in the winter period, the expansion tolerance increases to a centimeter. Facing with siding panels must be carried out immediately after finishing work on the insulation of the facade.

The most popular option for cladding the facades of buildings with siding over insulating material involves the use of crates made of wooden slats or a special metal profile. It is recommended to mount the crate to the wall using dowel-nails or galvanized self-tapping screws. A less common way is to use special brackets that are fixed to the wall surface at the stage of foam gluing. In both cases, the siding panels are fixed using standard hardware.

It is necessary to mount finishing siding panels on penoplex with a gap of about 20 mm. Sheathing must be carried out in accordance with standard technology, which involves the use of starting and finishing strips, corners and other additional elements.

insulation of a brick house from the outside with polystyrene foam for siding

Despite the natural attractiveness and durability brickwork, the facades of the building sooner or later require restoration and repair. Particularly relevant is the issue of wall decoration to improve the thermal insulation properties of structures, which helps to significantly reduce heating costs in winter time and increase the level of comfort in the summer. The best option is to insulate the walls of a brick house from the outside with polystyrene foam for siding. It is quite economical and effective solution. It is most applicable specifically for facing a brick building, but not for a wooden cottage, the thermal insulation of which is performed with completely different materials.

Siding finishing: the need to insulate the walls from the outside

Siding and insulation are often considered separately - as two independent processes. In fact, installation decorative coating cannot be carried out without high-quality thermal insulation of the walls from the outside, since the thermal conductivity of the siding is quite high. As a result warm air from the house upon contact with a cold surface will turn into condensate.

At sub-zero temperatures outside, drops of condensate will freeze and thereby increase microcracks in the walls. The result is premature destruction of those. That is why, when finishing with siding, it is better to insulate the walls from the outside in advance than to repair them later.

Features of insulation of brick houses

To significantly reduce heat loss and ensure comfort inside the building, it is important to choose the right insulation, its thickness, method of fastening and finishing. If we talk about finishing a brick house with siding, then the features of the technology are determined, it is only important to choose the material and its parameters as accurately as possible.

Material Choice: The Benefits of Styrofoam

For effective insulation the material must meet the basic requirements:

• have the lowest thermal conductivity: for example, this indicator for a brick is approximately 0.5 W / m * K, for wood - 0.13 W / m * K, for expanded polystyrene - 0.036-0.041 W / m * K;
• water-repellent properties;
• resistance to the development of bacteria and fungus;
• must retain its properties under significant temperature changes.

Extruded polystyrene foam meets these requirements to the greatest extent. Due to the air contained in the bubbles, this material has a very low thermal conductivity. The material does not absorb moisture at all if all the bubbles are intact. According to the manufacturers, such insulation is able to fade in the event of a fire, which is especially important when laying it under plastic siding.

It is important to know

Vinyl siding does not support combustion and it is recommended to use it when choosing materials.

It is with expanded polystyrene that it is recommended to insulate the walls of a brick house, especially since it belongs to the goods of the middle price category.
In numerous disputes about the choice between polystyrene foam and mineral wool, the first one wins, since it has been empirically proven that:

• Expanded polystyrene retains heat more effectively due to insulated air bubbles, while mineral wool slowly releases heat to the outside.
• The mineral wool used everywhere is inferior to polystyrene in terms of its thermal parameters.
• Mineral wool is able to absorb moisture, which is not subject to foam at all.

Despite these shortcomings, mineral wool has its advantages. It is ideal for the installation of structures using the technology of ventilated facades.

Disadvantages of Styrofoam

In order to avoid unpleasant consequences after finishing the facades, the following nuances should be taken into account:

• Expanded polystyrene is a combustible material, so it is not recommended for use in structures with air access, such as ventilated facades. In this case, the heater may flare up. (By the way, siding on a subsystem is just such a kind of ventilated facade)
• Rodents often start up in such a heater, but, as a rule, high-quality siding finishes prevent this problem from arising.

Insulation thickness

When determining given parameter it is important to take into account the properties of the main wall material, since the characteristics of the brick and the wall itself can be different. Hollow blocks and structures of substantial thickness have lower thermal conductivity. Accordingly, for such walls a smaller layer of thermal insulation is required.

Considering the fact that a foam layer of 120 mm is equal in its thermal properties to a brick wall of 2000 mm, it is necessary to correctly calculate the parameters of the insulation in each specific case:

• with a wall thickness of a brick house of 250 mm, the thermal insulation layer must be at least 40 mm;
• to insulate a wall of 500 mm, polystyrene foam 30 mm thick is enough;

The calculation of the thickness of the material also depends on the climate, since with an insufficient layer of insulation, severe frosts can lead to freezing of the main structures.

Technology of insulation of brick walls outside

Having chosen the material that is optimal in terms of cost and parameters, they proceed to the choice of fastening technology:

• Dowels, when the plate is fixed at five points, and the umbrella-hat covers the joints of the plates. At the same time, the process is quite laborious, but reliable.
• By using adhesive composition plates are easily attached to the walls of a brick house, if a clear horizontal line is observed, and the surface is leveled.
• With the help of cement-based plaster mixtures. This method of fixation is not recommended for brick walls, as the adhesion may not be effective enough. To increase adhesion, additional surface treatment is required, which increases labor costs and, accordingly, the cost and duration of work.

Any of these methods is used in conjunction with the frame, which is necessary for the further installation of siding.
Which method of fastening will be better in each specific case, is decided by specialists who will take into account both the parameters of the existing external structures and the characteristics of the load with the chosen method of fastening the insulation.

Stages of insulation

Often when self-insulation at home, the owners miss such an important preparatory stage, on which experts usually calculate the features of the operation of the house and climatic conditions, required thickness thermal insulation material and the load on the load-bearing structures. This is necessary to minimize costs and ensure maximum comfort.
Therefore, it is better to pay more attention to the calculations than to spend time and money later.
The insulation of the walls of a brick house from the outside occurs according to the following scheme:

1. First of all, the crate is mounted. Quite often this is used wooden slats, but for brick walls, metal profiles and brackets / hangers are considered optimal, although they are more expensive. Their cost is justified by a long service life without additional processing, which is needed wooden structures. They are fixed exclusively on a dry surface, repaired in advance if necessary.
2. Styrofoam plates are placed in the cells of the crate and they are fixed directly to the wall in the chosen way. You can also use another technology, in which the entire surface is first glued with polystyrene foam, and the crate is already mounted on top of the insulation, making holes for attaching the profiles directly through the thermal insulation layer, but this method is not the most the best option, as the amount of waste insulation increases.
3. Occasionally, two layers of insulation are used, which is justified in harsh climatic conditions.
4. Outside, a counter-lattice is mounted for installing siding: for a horizontal rail or profiles, they are laid vertically, for vertical installation facings - horizontally.
5. Next, install the siding. They start with corner, window, door and starting elements.

It is obvious that the process of insulating a brick house from the outside is quite simple, of course, if you have the skills, tools and understanding of the features of the process during subsequent siding.

Lifespan of styrofoam insulation

The question of the duration of operation of any material is always relevant, because it determines real value work and the feasibility of any investment. According to research, high-quality foam can last 50 years, of course, in ideal conditions - with minimal temperature changes, etc. Extruded polystyrene foam is credited with a service life of up to 80 years, in reality, adequate preservation of properties up to 40 years and a little more can be expected. This will contribute external protection facades for siding.
