Standard section of a bar for frame house– 150 x 150 mm or 200 x 150 mm, and this is often not enough to support comfortable temperature in the house in winter due to the thickness of the walls of the building. Therefore, insulation is required log house outside, and there are a lot of such technologies, as well as modern heat-insulating materials. It is considered an axiom that external insulation is much more effective than internal insulation, and this is true - the dew point shifts to a safe place, the amount of condensate decreases, the walls continue to “breathe”, but continue to retain and retain heat in the premises of the house.

Preparatory work on the outer walls

Before you start insulating a house from a bar from the outside, you should choose from the range of materials for thermal insulation the one that is best suited for a house of a particular design, select the technology for its installation and prepare the wall surfaces.

The preparation of wooden lumber walls is reduced to a visual inspection in order to detect cracks, mold and decay, detachment of islands of bark, defects in the installation and fastening of doors and windows, etc. Then the walls are caulked or gaps (if they are found) are sealed in another way, for example, putty with a special compound, the walls are treated with an antiseptic and fire retardant substances. Caulker outer wall it is carried out by one of the three well-known special heat insulators that have proven themselves better than others - these are tow, flax (lnovatin) and jute.

The insulation is pushed into the slots with a special wooden spatula with a narrow and thin blade. If there is no such blade, a metal construction spatula with a blade length of 60, 80 or 120 mm is suitable.

There are two ways to caulk walls: insulating the walls of a timber house from the outside, stretching, and laying in a set.

Stretched thermal insulation of surfaces is done in the presence of narrow slots, in a set - wide. In the first case, the ventilation façade insulation is stretched across the gap with a thin layer and driven in with a caulk and a hammer until the space is completely filled. Laying in a set is carried out by forming from balls to the size of the gap, then in the same way tow or jute is driven into the gap. The thermal insulation of a wooden house always starts from the bottom row.

When choosing a heat-insulating material, they start from its performance characteristics:

1. Compressive strength factor;
2. Frost resistance;
3. The service life indicated by the manufacturer on the packaging.

You can choose from the following list:

1. Fibrous inorganic heaters - glass wool, mineral wool, stone or basalt wool;
2. Styrofoam in plates and sheets of different density;
3. Expanded polystyrene extruded (EPP);
4. Polyethylene foam (EPE);
5. Sprayed polyurethane foam (PPU);
6. Plates "Isoplat" windproof.

Mineral wool and substitutes

Mineral wool is an excellent thermal insulator, but it is hygroscopic, and this disadvantage makes it a highly specialized material. Or, warming with mineral wool log house, it is necessary to create additional layers of steam and waterproofing materials, so the use of mineral wool is not a cheap pleasure. Choosing the insulation of a log house from the outside with your own hands from mineral wool, you should take into account the average annual air humidity in the region and the building materials with which the house is lined outside. Another requirement for mineral wool is that a ventilated facade must be equipped on the house.

Choose optimal material table will help:

Insulation foam

Styrofoam is chosen based on its density - high density means low thermal conductivity. The table below will help you correctly navigate the characteristics of the foam when insulating a house made of wood:

A log house can be insulated with any foam plastic with a standard sheet or plate thickness of 5 or 10 cm.

Insulation with extruded (EPS) polystyrene foam

Before you insulate the EPPS house from a bar, think about exceeding the estimate - this heat-insulating material costs much more than polystyrene foam and mineral wool.

XPS is attached to the walls with glue, which should not contain acetone, toluene, water, ethyl acetate and all derivatives of these substances. Therefore, when using this insulation, it is recommended to buy such glue:

1. Adhesive foam brand "TechnoNIKOL";
2. Glue "Ceresit" CT-85;
3. Adhesive facade composition "Allfix";
4. Glue "Bitumast";
5. Glue "Illbruck PU-010" based on polyurethane;
6. Adhesive composition "Insta-Stick Universal-145345".

Polyethylene foam NPE

The advantages of NPE over other thermal insulation materials are as follows:

1. Small coefficient of thermal conductivity;
2. The elasticity and elasticity of the material allows it to be laid on uneven surfaces;
3. Light weight and low cost.

Foamed polyethylene is produced as a heater high pressure(PVD) and low (HDPE), the material is foiled with an aluminum layer on one or both sides. IN individual construction The following brands of NPE are most often practiced:

1. Harness insulation "Vilaterm";
2. Roll heat insulator in the form of Thermopol mats. Mat thickness - 1.5-4 cm;
3. Roll insulation "Penofol". Has a foil layer on one or both sides.

When insulating a house with a layer of foamed polyethylene, it is not necessary to equip additional layers of vapor and waterproofing, and this is also distinguishing feature material - NPE is non-hygroscopic. And the low cost of polyethylene foam rolls gives good opportunity save the family budget without losing the quality of work on the insulation of the house from the outside.

Isoplat - windproof plates

The manufacturer is Finland, and everyone knows about frost there. "Isoplat" is made from fibers coniferous trees, without synthetic and harmful additives and additives. Standard sizes products - thickness 12 mm, length - 2700 mm and width - 1200 mm, in terms of heat retention properties, such a plate with a thickness of 12 mm is equal to 44 mm of a layer of pure wood.

The positive qualities of the insulation "Isoplat" ":

1. Sealed surface and elasticity, due to which the windproof plates cover the walls of the house very tightly;
2. Isoplat coefficient: λ10 ≤ 0.045 W/m K;
3. Good vapor permeability allows the wall of the building to breathe, so the possibility of mold and other fungal diseases is minimized;
4. High moisture resistance due to the impregnation of the boards with paraffin;
5. Noise isolation - 23 dB. For comparison: a three-chamber PVC window has a sound insulation of 47 dB;
6. With dimensions of 2700 x 1200 x 12 mm and a weight of one plate of 9 kg, quick and easy installation on walls is ensured;
7. Guaranteed operating time - ≥ 50-70 years;
8. Absolute environmental friendliness, as the material is natural.

The basics of warming a house from a bar

Wood is a hygroscopic material, so the surface of the walls can be deformed to a sufficiently large depth. Although the profiled glued laminated timber is impregnated with water-repellent substances, the material absorbs moisture, albeit in small quantities, but sufficient to cause wall deformations. First of all, deformations are manifested in the distortions of windows and doors, which have to be additionally insulated or remounted.

When insulating the house with Isoplatom, it is necessary to create a ventilation gap so that excess moisture comes out of the wood and does not deform it. Then a heat-insulating layer of slabs with decorative cladding made of siding, lining and other similar materials. Therefore, a ventilated facade for a timber building is required.

1. wall surface;
2. Wooden or metal crate;
3. insulation layer;
4. Vapor barrier;
5. ventilation gap;
6. Decorative protective lining.

Regardless of the material of the insulation, be sure to observe the correct layer-by-layer fastening of building materials. And the last: between a layer of any insulation and a layer decorative cladding an air gap of ≈ 10 mm must be left.

Insulation of a log house from the outside is necessary not only to ensure an optimal climate inside the rooms, but also to protect wooden walls from negative environmental influences. However, to ensure high-quality thermal insulation, it is not enough just to choose a material that will have a minimum coefficient of thermal conductivity, but also have natural properties. Is it difficult to insulate a log house from the outside or choose an internal method?

Insulation of the facade of a timber house from the outside has a number of the following advantages:

• during the external works uncomfortable conditions are not created for the residents of the house;
• the internal space of the premises is preserved;
• ensured additional protection load-bearing structures from negative external factors;
• the ability to easily change the cladding of the facade of the house;
• increases the life of the building;
• the dew point is outside the main structures, so the problems of dampness or condensation are not terrible;
• the natural properties of wood are preserved due to optimal air exchange with the external environment.

The disadvantages of this insulation technology include:

• work is permissible only under optimal climatic conditions: in the absence of precipitation and positive temperatures environment;
• necessity outer skin or finishes that may cause significant financial costs;
• it is possible to insulate the facade of the building only after the period of shrinkage of the beam has passed, namely after 1-2 years after its construction.

Types of materials for insulation

Insulation of the walls of a log house from the outside can be done using one of the following heat-insulating materials:

• polystyrene;
• mineral wool;
• extruded polystyrene foam.

Styrofoam

External insulation of a house made of timber with foam plastic is the cheapest way of thermal insulation. The material has a thermal conductivity coefficient of 0.03-0.04 W/m·K. It has increased moisture resistance (maximum absorption up to 1% of the total volume), so mold and fungus do not form on it.

The service life of the foam is more than 20 years, so maintenance of the insulated layer is not required during this time. During installation, there are also no difficulties or problems, since it is used minimal amount tools, laying is carried out quickly and efficiently.

Other benefits of polystyrene include:

• optimal level of sound insulation;
• minimal loads on load-bearing structures compared to other materials;
• ease of processing sheets;
• the possibility of applying a finishing layer directly on the insulation.

Mineral wool

Insulation of a timber house outside with mineral wool is the most common method of thermal insulation. The fibrous material has a natural composition, so it can contact wood without problems. Due to the softness of the mats, it can be tightly laid on the surface of any shape without air gaps.

The coefficient of thermal conductivity of mineral wool is 0.077-0.12 W / m K, depending on the type of fibers and the thickness of the plates or roll. Density varies from 10 to 100 kg/m 3 . The minimum service life is 20 years.

Insulation of a log house from the outside stone wool allows you to get the following benefits:

• high level of sound insulation;
• increased fire resistance;
• not prone to damage by rodents or pests;
• optimal vapor permeability and air exchange.

The use of extruded polystyrene foam (EPS) is the most profitable and expensive, as it easily tolerates conditions high humidity, external mechanical influences, contact with chemically active substances. Its service life is up to 100 years, that is, it has no analogues today.

The coefficient of thermal conductivity of XPS is on average 0.03 W/m·K. The level of moisture absorption is up to 0.4% of the total volume for 30 days. Unlike foam plastic, EPPS has a parapermeability of 0.05 mg / m·Pa·h and a uniform structure (granules with a size of 0.2 mm).

The density of the plates varies from 25 to 45 kg/m 3 , due to which the load on the walls can be accurately calculated. Compressive strength up to 0.16 MPa, and bending strength up to 0.25 MPa.

The main advantages of EPPS include:

• resistance to sudden temperature changes;
• environmental friendliness of the composition;
• resistance to the appearance of fungus and mold;
• chemical resistance.

Criteria for the choice of material and requirements for the technology of the insulation process

Proper insulation of a log house from the outside can be done with materials that meet the following requirements:

• optimal ratio of material thickness and strength, minimum coefficient of thermal conductivity;
• moisture resistance;
• incombustibility;
• so that the weight of the insulation can withstand the supporting structures;
• ease of installation;
• unpretentiousness in operation and undemanding maintenance.

The requirements for insulation technology are as follows:

• wood must be protected from external negative factors: temperature, moisture;
• heat-insulating sheathing must have sufficient strength, not shrink and withstand sudden temperature changes;
• all layers of the material should not accumulate moisture, that is, be well ventilated, or have increased waterproofing properties;
• the technological conditions of installation should allow the implementation of a specific method of insulation: evenness of the surface, the absence of obvious or hidden defects, the possibility of mounting guides, etc.

An important role is also played by the operating conditions of the insulation:

• temperature range in a particular area;
• building features: fire hazard, the possibility of contact with various chemically active substances, the likelihood of mechanical damage;
• the minimum duration of operation of the insulation under specific conditions;
• the need for maintenance.

Therefore, when choosing a material, it is important to take into account all the influencing factors. Only in this case it is possible to ensure the maximum period of their operation and the absence of problems with the timber. It is also worth paying attention to the additional properties of the insulation, which will save on laying sound or waterproofing.

Features of preparing the walls of the house for insulation

The technology of warming a log house from the outside requires the following conditions and preparatory work:

• a wooden house must go through a period of shrinkage into the ground after construction;
• wood must be impregnated with antiseptics and protective impregnations that reduce flammability and moisture absorption;
• all cracks and defects must be sealed, if necessary, several logs must be replaced;
• consideration must be given to how the materials will interact with the timber in order to ensure the longest possible service life.

Options for external insulation of a log house

Warming a log house from the outside with your own hands can be done using one of the following methods:

• with the help of a hinged ventilated facade;
• by spraying a polyurethane layer;
• sheathed with foam.

Installation of a hinged ventilated facade

The installation of a ventilated facade involves the installation of a lathing with laying in the space between the insulation guides and subsequent sheathing with facing panels. Mineral wool boards are used as heat-insulating material.

The main advantages of this technology are:

• increasing the level of hydro and sound insulation of walls;
• ease of installation;
• minimum requirements for surface evenness;
• wide choice of finishing materials;
• displacement of the dew point from the supporting structure to the insulating layers;
• ease of maintenance and repair of the hinged frame.

The implementation of the method is as follows:

1. Held preparatory work: wood is treated with impregnations, defects are removed, etc.
2. A wooden or metal crate is mounted along the width of the insulation.
3. A waterproofing layer is laid.
4. Insulation is mounted between the guides.
5. The insulation is sheathed with a windproof membrane.
6. The counter-lattice is laid along the slats of the main batten.
7. Sheathing is carried out with boards or decorative panels.

Insulation under siding

The insulation of a log house outside under the siding is similar to the thermal insulation technology by the method hinged facade. However, there are a number of features:

• as a heater, you can use mineral wool or EPPS;
• joints of thermal insulation and guides are sealed with mounting foam;
• when using mineral wool, a diffusion membrane is used as a waterproofing;
• when laying XPS, siding can be installed directly on the main crate, since waterproofing is not required.

Spraying a polyurethane layer

Polyurethane spraying is an innovative method, the most effective and expensive among all existing ones. It is with its help that it is possible to form a sealed seamless layer that is highly resistant to negative external influences: moisture, sudden temperature changes, and pests.

The advantages of this technology are:

• maximum protection of timber from decay;
• improving the fire resistance of walls;
• increased adhesion of the applied layer to various building materials;
• no need to level the base;
• fasteners are not needed;
• increases sound insulation;
• high layer uniformity.

However, there are a number of negative points:

• the difficulty of applying a uniform layer;
• the need to use special equipment;
• high cost of polyurethane foam;
• instability to direct ultraviolet rays.

The method is implemented like this:

1. The surface of the walls is cleaned from dirt and various stains.
2. Wood is treated with antiseptics and other protective compounds.
3. Installed wooden guides.
4. Spraying polyurethane foam. If necessary, two layers.
5. The cladding is installed.

Foam insulation

Thermal insulation of walls with foam plastic is very profitable and inexpensive, since the material is relatively cheap, easy to install and unpretentious in operation. In addition, laying the crate is not required, finishing can be done directly on the insulation, with sharp temperature fluctuations it does not lose its properties.

Styrofoam is a combustible material, therefore it is necessary to treat wood with impregnations that increase the ignition temperature or make it non-flammable (flame retardants).

The warming method is implemented as follows:

1. A vertical crate of wooden bars is mounted to the walls. Their thickness is equal to the thickness of the insulation, and the fastening step is equal to the width of the plates.
2. Styrofoam sheets are butt-mounted inside the frame. The seams are glued with sealant or heat-insulating tape. The foam is fastened to dowels, called "umbrellas", or to an adhesive base.
3. A diffusion membrane is laid on top of the foam butt. All joints are glued with special adhesive tape. The membrane is fastened to the staples using a stapler.
4. The facing layer is installed.

On preparatory stage installation of polystyrene foam, it is important to carefully align the walls, since at the slightest bends (more than 1.5 mm per running meter) cracks may appear in the sheets. In addition, this will save on the consumption of a layer of plaster.

For plastering walls, it is not necessary to install a crate, since the load on the decorative layer is minimal. However, there is one important condition– it is necessary to lay a reinforcing layer in order to increase the engagement area of ​​the outer layer and the mechanical strength.

To make a house made of timber cozy, warm and inexpensive to maintain, to reduce heating costs, then external insulation methods are the most profitable. Their implementation is relatively simple, and there are a lot of advantages: lower heating costs, protection of load-bearing structures from temperature extremes, pests, mechanical, physical and chemical influences.

When choosing materials for insulation, it is necessary to be guided by the requirements for thermal insulation and the total budget for all stages of work.

Houses made of timber are becoming increasingly popular among Russians, however, their main drawback is their inability to withstand the harsh Russian winters due to some features.

The fact is that the average thickness of a house made of timber is about 150 mm, and this is not enough to keep the house warm and comfortable in severe winter frosts.

The optimal section for walls made of timber is 40 cm, it was this thickness that was enough to keep the house warm in winter.

But not all houses made of timber have such wall thicknesses. Therefore, in order to make the dwelling comfortable and cozy not only in summer, the question arises of how to properly insulate houses from a bar from the outside.

What to choose: insulation from the inside or outside?

Much more often, a house made of timber is insulated from the outside, and this happens for several reasons. Firstly, at the same time, less usable living space is stolen, and the tree will be better protected from the negative effects of natural factors.

It is possible to insulate a house from a bar from the outside with your own hands, and well-executed thermal insulation will help maintain a comfortable temperature inside the house.

In addition, if the insulation of the house is carried out in compliance with all the nuances, then utility bills will also decrease, namely the payment for gas or electricity, which will favorably affect the family budget.

What materials can be used to insulate houses from a bar from the side of the street?

The modern building materials market is rich and diverse, manufacturers offer various insulation materials for houses made of timber, such as polystyrene foam, mineral wool, basalt insulation and some others.

What material to choose for warming a house from a bar?

For this, the following factors must be taken into account:

• The cost of insulation (initially, you should decide how much you are willing to spend on warming the house),
• Its quality
• The level of thermal conductivity,
• The elasticity of the material for insulation,
• sharpen Special attention on how easy it is to carry out work on warming a house with the help of one or another heat-insulating material (this nuance is relevant when carrying out installation work on one's own).

The choice of insulation

In order to properly insulate a house from a bar from the outside, you should take a responsible approach to the choice of heat-insulating material.

Most often, mineral wool is used to insulate a home, since, compared to its competitor, polystyrene, mineral wool is less combustible material, which favorably affects the fire safety of the home.

In addition, this building material is environmentally friendly and has good technical characteristics.

So, mineral wool conducts heat and cold very slowly.

Preparatory work

Before purchasing the selected insulation, you need to carry out simple calculations and draw up an estimate of the costs of warming the house. In addition, it is necessary to carefully calibrate the amount of material that will be required for insulation.

Mineral wool insulation is sold in three forms, in the form of plates, mats, and rolls. The easiest way to work with plates.

But in order to purchase the required number of them, one should take into account the fact that if the thickness of the walls of the house is less than 20 cm and the winter temperature often drops below the mark of 20 degrees, then it will be necessary to insulate the walls with a double layer of mineral wool, therefore, it will be necessary to purchase insulation in 2 times more.

Some professional builders advise to insulate the house with several materials, combining them, for example, sew polyethylene foam on the facade, and insulate the rest of the house with mineral wool.

What else is needed for thermal insulation work?

In addition to the insulation itself, some other things will also be required:

• Waterproofing film, which should be purchased 10% more than the area of ​​\u200b\u200bthe walls (this is done because the film overlaps),
• Level for marking,
• Construction stapler for fixing the film,
• Antiseptic for walls,
• Screws and self-tapping screws for fastening work,
• A certain amount of timber of small section.

The procedure for warming the house

Many people ask professional builders the question of how to properly insulate a house from a bar from the outside and what is the sequence of actions for carrying out thermal insulation work.

So, first you need to treat the walls with an antiseptic, while it would be better to use a product that gives protection against mold and fungus. After application, the antiseptic must dry completely, only then you can proceed to the most important installation work.

After that, it is necessary to make a crate, for this, bars of a smaller section are attached to the walls of the house. Moreover, you need to start fixing them precisely from the corner of the house and vertically at the same distance.

This is the future "framework" for the installation of mineral wool.

Now you can proceed to the installation of mineral wool, but pre-slab with an ordinary knife should be cut into rectangles of the required size.

It is required to take into account the fact that you need to cut mineral wool a little wider than the distance between the bars.

We fix the mineral wool up to the very roof with special anchors, which should be located at a distance of about half a meter from each other.

After that, it is necessary to apply another layer of insulating film, but now with the glossy side out. In order for the film to hold, it again needs to be fixed with a construction stapler.

Additional related materials:

Warming of the house with mineral wool is completed. It remains only to finish the facade of the building from above with the selected material.

Thus, we can conclude that the installation manipulations for the thermal insulation of the house from the outside cannot be classified as complex. construction work, this can be done independently, the main thing is to take into account all the essential aspects and follow the instructions.

It is very important to carry out thermal insulation works qualitatively, since competent installation of insulation is a guarantee that your home will be comfortable and cozy for many years.

Insulation of a log house from the outside

Many now have a question, does this traditional construction technology not imply high-quality heat preservation with timber? The fact is that the lumber technology was developed for more favorable climatic zones, and we in Russia have to deal with additional insulation to make the microclimate in the house more favorable and reduce heating costs.

Of course, you can sheathe the timber with siding without insulation, but it is worth doing quality work with the walls, as heating costs will drop sharply. But before you insulate a log house from the outside with your own hands, you will need to choose a heater, calculate its amount and required thickness. This is an estimate that should be financially met. Consider an easy-to-install insulation with undeniable advantages.

Selection and calculation of material for the walls of the house

Today, in the market of heat-insulating materials, the most popular are foam plastic, foam plastic (extruded polystyrene foam) and mineral wool insulation. We will opt for mineral wool and proceed to consider the advantages of this material. This insulation does not burn (the main and indisputable advantage), it is environmentally friendly, the thermal conductivity of mineral wool is 0.036 W / m2,

Scheme of wall insulation from a bar outside

The next step is to calculate the amount of material and the thickness of the insulation layer, which will be suitable for our climate and design features walls. mineral insulation Sold in slabs, mats and rolls. It is easier to work with plates, so we will choose this type for calculation. Taking into account that the surface of the walls is even, and standard thickness plates 50 mm, we begin to count.

If the wall thickness is 20 cm, and the lowest temperature in winter is 20 ° C, then we lay the mineral wool in one layer. If the thickness of the walls from the timber is 20 cm, and the temperature in winter drops below 20 ° C, we lay the insulation in two layers. The calculation depends on the average value of the climatic conditions of the region. To accurately calculate the thickness of the insulation, use the heat engineering calculator on the site.

Do-it-yourself insulation of a house from a bar outside

How to insulate a house from a bar outside? Let's get to work necessary tools, materials and get to work. Additionally, you will have to buy: a waterproofing film with a margin of 10-15% of the wall area, anchor screws, wood screws, an antiseptic, a small cross-section beam. Also prepare a set of tools - a hacksaw, a hammer, an ax, nails, a construction stapler with staples, a level, a brush, etc.

We prepare the walls of the house for insulation

Warming a house from a bar with your own hands

We process the walls with an antiseptic with a brush or roller. We process the wall several times and wait for complete drying. Do not forget to check the quality of the caulking of the walls, caulk the walls if necessary. After that, we begin laying the waterproofing film with our own hands, using a stapler, shoot it to the beam with an overlap between the strips of 10-15 cm. We glue all the joints with adhesive tape.

Fastening the crate from a bar

It is important to start the crate from the corner, and we try to mount the vertical guides at the same distance from each other, we check the level or plumb line. Between the timber, the insulation should be laid closely with your own hands, and a finish will be attached to it - vinyl siding or pvc panels, so the distance between the timber should be 1-1.5 cm less than the width of the mineral wool slabs.

Installation of insulation on the walls

Installation of insulation on the walls of the timber

Having installed the mineral wool, we drill holes in the wall and install a dowel-mushroom in the form of an umbrella. Plate fastenings can be done in increments of 40-50 cm. Having fully installed and fixed the insulation to the very roof, we cover the wall with a second layer of vapor barrier, fasten it to the beam with a stapler. Vapor barrier is necessary to protect the mineral wool from moisture, so the film should be laid with a smooth side to the insulation.

The waterproofing film does not allow moisture to pass through in one direction and calmly allows it to exit from reverse side- this property is great for waterproofing and wall insulation in the bath. Do not forget to read the instructions of the manufacturer of the vapor barrier film, so as not to make a mistake when installing it. The insulation is almost completed on this, and you can start finishing the facade with a planed board. See below - how to insulate a house from a bar outside with mineral wool.

Do-it-yourself insulation of a house from a bar outside
In the article, we will consider the technology of warming a log house from the outside and offer a technology. We also picked up a video instruction from the company on this topic.

The climate in Russia is extremely harsh, the winters are cold, so the question of how to properly insulate a house from a bar from the outside is relevant. This work must be done very carefully, especially from the outside of the house, only then will we get the conditions for year-round living.

Insulation with mineral wool insulation.

Features of housing construction in Rus'

Naturally, the question arises, but how did you manage without warming the house from the outside before? After all wooden houses built in Russia since ancient times, they stood for centuries.

It must be understood that an old and reliable log house and a modern house made of timber are somewhat different concepts. Until the 20th century, only chopped wood was used for buildings. Preference in carpentry was given to an ax, although the saw was known in Rus' from ancient times.

But it was believed that sawn wood absorbs moisture more strongly, swells and rots. And the wood in the logs, which are processed with an ax, seems to be clogged under its blows and does not absorb moisture.

Houses were built without nails, there were several ways to cut logs. The cups were cut down strictly according to the shape of the logs that fit into them, a longitudinal groove was made in the crowns for better density log house. The log joints were carefully caulked.

All this gave the effect of monolithic. The thickness of the logs in the log house was sufficient to maintain heat.

House with a male roof, XIX century.

Another feature was the erection of a frame under the very roof, the design of which in this case was called male. This type of structure was especially widespread in the north of Rus'. The logs were lifted up to the very roof, they built a triangle of the pediment, on which they fastened the slabs for the board.

So, we see the following features that prevented the traditional wooden houses in Rus':

1. wall thickness sufficient to retain heat,
2. solidity of the walls, achieved by the density of planting logs and the caulking of cracks,
3. low level of hygroscopicity of wood due to its processing with an ax.

Let's consider these features in application to modern houses from a beam.

Modern log house

Modern house from a bar with a section of 150 mm.

For a normal microclimate level in the house, when winter frosts are fierce, it is necessary to build a house from a bar with a thickness of 40 cm. After all, the timber simply by itself will freeze through and through in severe frosts.

In modern housing construction, a beam with a cross section of 150 mm is used, so such a house has to be insulated from the outside or from the inside. The most appropriate to achieve the desired effect is considered to be the external insulation of a log house.

The level of hygroscopicity is reduced by treating the timber with special impregnations. By using various methods external insulation, it will be possible to achieve the effect of solidity and sufficient wall thickness, the main thing is to correctly find the answer to the question of how best to insulate a house from a bar from the outside.

Benefits of outdoor insulation

The advantages of the method of warming the house from the outside are as follows:

1. the internal space is not affected, it is possible to carry out work without disturbing the normal rhythm of the life of the owners,
2. the ability to perform insulation work with your own hands, without the involvement of specialists,
3. there is an opportunity original solution house facade,
4. heat loss is reduced
5. external walls will be protected from the adverse effects of the external environment.

Heaters

Basalt wool thermal insulation - Light Butts.

The modern market is rich in materials that are used for wall insulation:

1. basalt insulation,
2. glass wool,
3. Styrofoam,
4. extruded polystyrene foam,
5. foam polyethylene,
6. polyester fiber insulation
7. sprayed polyurethane foam.

The photo shows Penofol-A foil thermal insulation made of polyethylene foam.

When deciding how to insulate a house from a bar from the outside, it is necessary to take into account many factors, take them into account and draw the right conclusions. In this matter important role play the price, quality and thickness of the insulation.

To accept correct solution, it is necessary to consider all the comparative mechanical and thermal characteristics of heaters, given that the characteristics of materials produced by different manufacturers may differ.

What features should be paid attention to when deciding how to insulate a timber house from the outside:

1. thermal conductivity index,
2. compressive strength index,
3. indicator of elasticity, elasticity (this is important for understanding the ability of the material not to break when bent and restore its original shape),
4. study the installation conditions (manufacturer's instructions on how to install this insulation are attached to each material).

Advice. When choosing the thickness of the insulation, you can face the choice that a mineral wool insulation with a thickness of 50 mm will be insufficient for walls of 150 mm according to the requirements of SNiP 23-02-2003 "Thermal protection of buildings", and with a heater with a thickness of 100 mm it will significantly exceed them.

In this case, you can use a combination of different heaters. For example, use foamed polyethylene, covering the facade with it right along the vapor barrier, and sew bars on it, between which to strengthen the mineral wool insulation.

The procedure for carrying out thermal insulation work

Consider how to properly insulate a log house from the outside, what stages of work must be completed and in what sequence.

In order to prevent air vapor passing through the thickness of the timber from turning into water in the thickness of the insulation, it is necessary to make a vapor barrier. Best Option it would be to hold it from the inside of the walls, made of foil material that reflects heat into the room.

An option for insulating the walls of a house from a bar with vapor barrier inside the room (1-outer sheathing, 2-counter rail, 3 wind protection, 4 - insulation, 5 - load-bearing wall).

Consider how to insulate a log house from the outside when interior decoration has already been completed and it is necessary to provide for a windproofing device from the outside (see also the article Finishing a house from a bar inside on your own).

You need to do it in the following order:

1. we fill the vertical crate on the outer walls from edged boards with a thickness of 40-50 mm,
2. we fasten the vapor barrier membrane on the boards with a continuous overlap,
3. we fill the second layer of the crate on the same boards with a step suitable for the selected insulation,
4. we lay the insulation between the bars,
5. we lay a film or membrane for wind protection,
6. we fix the wind protection with counter rails,
7. we mount the outer cladding on the rails.

Important. The vapor barrier of the wall must have air vents arranged from below and from above. This is necessary to circulate air and balance the temperature in the area of ​​​​the gap and the temperature in the interior.

How to insulate a house from a bar from the outside to create a comfortable atmosphere in it
How to insulate a house from a bar from the outside correctly with your own hands: do-it-yourself installation instructions (photo and video)

Many individual developers insulate a log house from the outside with their own hands in order to save money. The best option consists in laying heat-insulating material under finishing coating. As such, vinyl siding is often used, which allows you to reliably protect the building from external influences for an affordable fee.

The photo shows the main work.

Advantages of this option

In this case, elements are set supporting structure, between which mineral slabs are laid, capable of providing high-quality thermal insulation of the structure. The insulation is covered with a waterproofing film. To the elements wooden crate vinyl panels are attached.

Enumeration of merits

• The price of the materials used is relatively low, which means that the final design is not too expensive,
• The absence of complex construction processes allows you to carry out all the work yourself,
• Siding panels are resistant to external influences, so they can long time protect the insulation
• The mass of all products is not so large, so there is no need to strengthen the facade before the main operations.

You can even transform such a structure from a bar.

Addition!
When thermal insulation made of mineral wool is laid under the siding, it is possible to level side surfaces buildings, since the device of the supporting structure is a prerequisite.

Installation

Further instructions will help you understand how to properly insulate a log house from the outside directly under the siding finish. If the basic rules are followed, then you should not worry about the quality of the work performed, even if you do not have solid experience in construction.

Necessary materials

• Bars with a section of 50 × 40 or 50 × 50 mm are required to create cells in which insulation will be laid,
• Vapor barrier material is needed to protect thermal insulation from exposure from the inside of the building,
• Slabs or rolls of mineral wool are needed to form a barrier against heat loss,
• The waterproofing membrane will protect the insulation from the outside directly from moisture,
• An edged board will be required for the construction of a crate for facing,
• Siding panels and components are purchased for finishing work,

The boards are supplied in small packages.

Note!
During the installation process, nails and self-tapping screws of various lengths will be needed to fix the fragments of the structure.
The final size of fasteners depends on the materials used in each case.

Tools Used

• Hammer,
• Hacksaw or any other cutting tool,
• nail puller,
• screwdriver,
• long string,
• Building level,
• simple pencil,
• Tape measure at least 5 m long,
• metal scissors,
• stapler.

thermal insulation process

Before starting work, it is necessary to remove from the facade of the building all objects that will interfere. The platbands are completely torn off the windows and doors, decorative slats are removed in the edging places, visors and other elements are removed.

Satellite dishes, lights and stationary structures can be left in place.

Approximately so the thermal insulation should be laid.

1. First, a vapor-tight membrane is spread. It is fixed directly to the wall using a stapler. When laying the canvases, a small overlap is necessarily made. Manufacturers usually make special labels,
2. Bars 50 × 50 mm are taken and fixed in a horizontal position to the side surface of the structure. A distance should be left between them, which will be 1-2 cm less than the width of the heat-insulating plate. For fastening, self-tapping screws with a length of at least 65 mm are used,
3. Next, mineral wool insulation is carried out. Fragments of material are inserted between the established wooden blocks close to each other. First, one edge of the plate is started, after which the other is carefully refueled. If necessary, the elements are cut with a clerical knife,
4. After laying the heat-insulating material, a waterproofing film is attached to the bars. It is fixed according to the same rules as the vapor barrier membrane. The overlap on adjacent canvases should not be less than 10-15 cm.

Material for waterproofing.

Attention!
Bars for insulation at the installation stage do not require alignment.
This will be done in the next step.
The elements are tightly applied to the side plane and fixed with self-tapping screws.

Lathing device

After the thermal insulation layer has been created, a crate is erected for facade material. The basic elements are edged boards. Their thickness should not be less than 25 mm, otherwise guarantee long term support structure service is not possible.

First you need to prepare the corner elements for installation. It is best to take two boards at once and connect them so that a right angle is formed. Similar products it is recommended to fasten directly to the edges of the wall. Their alignment should be carried out using the building level.

The wooden crate is shown.

When the corner elements are fixed, it is necessary to stretch the twine from one of them to the other. It will help to set intermediate racks for coverage at the same level. The optimal step is 40 cm. It is this distance that allows you to save on lumber without compromising quality.

After the erection of the supporting structure, the siding is directly installed in compliance with all the rules.

Important points when installing the coating

• Between constituent parts finishing should be a distance of 7 to 11 mm, since plastic is used as the main material for the manufacture of panels and components,
• First of all, elements for the design of joints, corners and openings, as well as start and finish profiles are mounted, after which vinyl panels are installed,
• Fasteners in the form of self-tapping screws and nails should not be driven in to the end to compensate for linear expansion, otherwise cracks and chips may appear on the coating,
• The fixing elements should be located strictly in the central part of the perforations, otherwise the trim fragments may be deformed, which will lead to additional costs and time.

On this moment timber is one of the most popular materials for building houses. But to make a house out of this natural material could serve for many years and not freeze in the winter, it needs to be properly insulated. And it is necessary to insulate the house in detail, because during frosts the timber itself freezes. Therefore, processing and caulking cracks cannot achieve the desired result. Only an integrated approach to the task and the study of all options will create warmth and comfort in the room, despite the seasons.

Why is it more practical to insulate a house from a bar from the outside

• Such insulation let change appearance Houses and decorate it afterwards at your discretion.
• External insulation reduces heat loss V heating season thus saving money on heating.
• The tree is susceptible to negative external influences environment, so insulation from the outside will stop this process.
• Another important positive factor performance of work on insulation from the outside of the log house will be the ability not to disturb the order of life with repairs in the house itself.

What are the methods of external thermal insulation

There are three common ways to insulate houses from timber:

• By creating a ventilation facade.
• Sprayed polyurethane foam.
• Insulation of the walls of the house with foam boards.

The most convenient and optimal way counts creation of a hinged ventilation facade, which can be easily mounted with your own hands. And already on top, apply any facing texture that is suitable for the plan. For such purposes, wood, wall paneling, porcelain stoneware, brick, siding are suitable.

Insulation of houses made of timber, therefore, is very practical and durable, since this type of insulation does not lend itself well to external atmospheric phenomena, which is what consumers need. Another benefit of a ventilated façade is that it increases the sound insulation of the home. And of course, it has an increased level of heat protection, which is primarily required.

Work on the insulation of houses from a bar

The technology of the ventilation facade method is simple. Insulation materials are attached to the walls of the house. And already according to this design, the necessary finishing is done in compliance with the abandonment of airspace. Thus, the beam of the house does not rot, does not dampen and does not freeze at sub-zero temperatures.

Thermal insulation for siding has gained particular popularity at the moment; it is equipped on an installed wooden base. To carry out such work on your own, you will need a hacksaw, tape measure, plumb line and level, dowels, self-cuts, insulation, beams and cladding. If you have all the required materials, it will not be difficult to insulate a house from a bar.

Used as wall insulation thermal insulation materials, How:

1. glass wool;
2. basalt slabs;
3. mineral wool (used with a moisture-proof diffusion membrane);
4. expanded polystyrene.

All of the above heaters are highest safety performance by a person and do a good job with their main task, retain heat, isolating the room from external influences. Moreover, they are safe for the environment, which is also of great importance.

Installation of insulation material

First stage of installation insulation material is to mark the location horizontal lathing. In doing so, it must be taken into account that step wooden beams equal to the width of the insulation boards. And the cross section of the bars should correspond to the thickness of the plates.

Fasten the bars to the base of the wall using self-tapping screws. To control the level of the horizontal crate and not to warp the structure, you must constantly use a plumb line and a level. It hinders education uneven surface, which will subsequently ensure the quality of the subsequent stages of insulation.

After the complete installation of the crate structure, it is necessary to lay the prepared insulation material. One of important points of this process is that it is necessary to ensure that the insulation plates fit snugly against the bars and against the wall. Insulation materials are fixed with special dowels. These can be dowels with a parachute or umbrella head.

Now it is necessary to make an air gap on the structure, which is so important for this method of warming the timber base of the house. It is made by mounting a vertical crate. When attaching it, you need to take into account the fact that the distance from the horizontal crate should not exceed five centimeters.

If in the process of thermal insulation mineral wool was chosen as a heater, then very important work must be done to protect this layer from moisture. For this purpose, a diffusion membrane is used. The diffusion membrane is a perforated film, which allows evaporation to the outside, but prevents condensate from entering the insulation. Thus, preserving all the primary properties of mineral wool, preventing its moisture.

Other mentioned heaters do not need additional funds.

How houses are insulated from timber using polyurethane foam spraying

One of the new methods increasingly used for insulation is polyurethane foam spraying. This is currently a very effective method that meets a number of necessary functions that modern consumers require for insulation. Such the insulation is environmentally friendly, does not burn, is not affected by bacteria and decay.

Moreover, applying it with your own hands is also not difficult. The process consists in the fact that under pressure in the sprayer itself, two liquids are mixed, which foam and solidify on the insulated surface.

For excellent sound insulation and thermal protection, it is enough to spray a small layer of such an insulating material on the outside. Insulation of the timber surface will not require additional treatments. But if there is a desire, then the layer can be increased to any thickness from the customer's requests.

This insulation is good because they can make insulation with their own hands, not only a timber house. Polyurethane foam spraying can also be used to insulate all the necessary basement buildings. With it, you can easily insulate the foundation of the room.

Wall cladding with wooden planks

Not all trees are suitable for insulating walls made of timber from the outside with boards. For these purposes, you need to use boards of pine, oak, larch. The thickness of the board must be at least twenty-five millimeters. With such parameters, both the walls of the house and the sheathing itself "breathe" better.

When installing cladding wooden planks it is important to remember about the gaps in the upper and lower edges of the facade that need to be made. As a protection against snow and rain for these slots, you need to use special visors that are mounted above them.

As you can see, warming a house from a bar from the outside can be a fairly simple task even for beginners in this matter. The main thing is to study the task, decide on the material that is best suited for this case and proceed without haste.
