How to insulate a wall in an apartment from the inside using different materials. How to insulate a wall inside an apartment. Insulating a panel house - nuances you didn’t know How to insulate a panel wall in an apartment from the inside with your own hands

Over time, the walls of a panel house need additional insulation. Unlike brick buildings, when there is a difference in temperature, they can freeze and accumulate moisture, which leads to the destruction of the external facade of the house, the appearance of cracks, mold and other unpleasant changes. Residents may notice that the apartments are cold, despite the presence of heating. To eliminate the consequences of such changes, and to maintain the level of heat inside as much as possible, it is recommended to insulate the panel house from the outside.

Advantages of external insulation

External insulation of the house will not only avoid heat leakage through the walls, but will also protect the facade from further destruction. Using various options decorative design in exterior decoration the house will look new. In addition, insulating walls from the outside has the following advantages:

• there is no need to evict residents from the house during repair work,
• increasing the temperature inside the building by protecting walls from freezing and other adverse effects of weather conditions,
• no resizing interior spaces– the entire living space is preserved,
• insulation technology strengthens supporting structure panel house, the building becomes more durable and its service life increases,
• a layer of insulation on the outside acts as additional good sound insulation of the building.

External wall insulation is most effective for panel houses– it is possible to save up to 50% of heat.

Types of insulation

The choice of which material is best to insulate the walls from the outside is influenced by:

• location of the panel house in a certain climatic region,
• amount of precipitation, wind strength and speed,
• allocated budget for insulation of a panel house,
• other individual factors.

useful in work

The estimate and project for the work is usually Management Company or HOA. A team of industrial climbers directly carries out the insulation process from the outside.

For panel houses, two types of insulation are mainly used:

Mineral wool

For outdoor work, it is convenient to work with mineral wool slabs, which are produced by various manufacturers. It has good performance in basic characteristics, including thermal conductivity. However, you need to ensure that the mineral wool does not get wet, otherwise it will lose its thermal insulation properties. To do this, a vapor-permeable membrane is laid under the insulation layer, which will protect it from vapors.

When finishing a ventilated facade, condensation from the walls of the house will be removed due to the air gap and the membrane does not need to be used.

Styrofoam

It is distinguished by its lightness and simplicity when laying slabs on the wall. It also has good parameters for heat and sound insulation. For outside work, it is important to use a material that does not support spontaneous combustion. Manufacturers mark it with the G1 marking, however, the results of many tests confirm that the foam is flammable, and this name does not meet the requirements of GOST 30244-94. When purchasing insulation, be sure to ask the seller for product certificates.

It is important to know

The insulation of a panel house from the outside is limited by the thickness of the insulating material. The maximum value of the foam thickness for walls is calculated using special formulas, taking into account the average temperatures in a certain climatic region and the purpose of the building (residential, public, industrial).

Stages of the facade insulation process

Depending on the chosen insulation method, installation will vary. There are two main technologies:

1. Wet Facade
2. Ventilated facade

The process of insulation using the “wet” method is described below.

Preparing the wall surface

It is necessary to carefully prepare the surfaces of the facade of the house in order to insulate it efficiently. Each wall is leveled, cleaned of various deposits, voids and cracks are sealed, especially paying attention to the joints of the panels. If necessary, they put a sealant in them, coat the cracks with special mastics.
Unevenness of the wall surface is allowed within 1 - 2 cm, but no more.
After cleaning and processing the joints, the walls are left to dry. Next, they are coated with a universal primer using a roller or sprayer.

Installation of insulation

Attaching thermal insulation material to walls is possible in three options:

• on glue,
• for fasteners (dowels, plastic nails),
• combining glue with fasteners.

The video shows in detail the method of attaching foam plastic using dowels for thermal insulation.

For example, polystyrene foam is fixed using a combined method from the first floor to the upper ones. A starting strip is installed at the bottom, from which the insulation begins to be glued. In this case, the glue is carefully applied to the walls with a spatula, filling the existing unevenness. Then the foam sheets are pressed tightly onto the treated surface. The evenness of the rows of insulation is checked with a level. It is possible to correct minor errors before the adhesive base sets. Now you need to wait 2 - 3 days for the glue to dry completely and for the insulation to adhere well to the walls. Next, the foam plastic is additionally secured with dowels - 4 - 5 pieces per sheet. Holes for fasteners are made with a hammer drill.

The second and subsequent rows of foam sheets are laid in a checkerboard pattern so that the joints of adjacent layers do not coincide. All seams between the insulation and the cracks from the fasteners are filled with special polyurethane foam, intended specifically for the installation of foam plastic, in order to minimize the likelihood of heat leaks. This foam is produced in cylinders and is best applied with a special gun. The excess and remaining foam is cut off after drying.

Pinning the grid

Polystyrene foam is a fairly fragile material, so it is reinforced to give strength and rigidity to the insulation elements. To do this, a special stable mesh is installed on the outside of the foam sheets. It is convenient to cut it into separate pieces of the same size and overlap it in small fragments. A layer of a special adhesive solution for facade work is evenly applied to the insulated surfaces, and the mesh is pressed into it. Then another adhesive layer is applied for leveling. After installing the mesh over the entire house, wait for the glue to dry before treating the surfaces sandpaper from mortar leaks and unevenness during the fastening process.
The reinforcement provides mechanical stability for the final decorative covering panel house.

Finishing

After insulation external facades, as a rule, are decorated with decorative plaster. For the best adhesion of materials, the general layer of thermal insulation is primed again.
In addition, the technology of suspended ventilated facades is often used for residential apartment buildings. The thermal insulation layer has already been completed - all that remains is to install the outer cladding with a ventilation gap.

Today it is offered wide choose materials for exterior finishing in a curtain façade system:

• metal products (corrugated sheeting, siding, facade cassettes),
• aluminum composite panels,
• slabs made of porcelain stoneware, natural or artificial stone.

Each of them can be selected according to its external structure, color scheme and other characteristics.
Ventilated façade technology not only protects the walls of a building, but also makes it possible to implement a variety of design ideas and solutions.
To attach a ventilated facade, an additional frame will be required.

The process of insulating panel houses can be carried out during their reconstruction or major renovation. If your choice falls on the “wet” facade technology, it is advisable to plan work in the summer or at temperatures above 5°C. When using ventilated facades, installation can be done all year round.

If you have experienced the purchase or sale of apartments, then you have noticed that buyers do not really like corner apartments or rooms. What is this connected with? Although it is much easier to ventilate such an apartment in summer, the view from the windows opens on two or even three sides.

But there is one significant drawback. Very often, with the arrival of frost, residents of corner apartments suffer from insufficient heat. If the temperature outside is around zero, and the heating season has not yet begun, uncomfortable conditions are created inside such an apartment. It appears, the windows fog up, the floor becomes cold, and the bed becomes damp.

The main reason for this is the presence of three walls that have access to the outside and are therefore most susceptible to low temperatures. In winter, even if available central heating, the situation is only getting worse.

The walls can freeze completely, especially in the corners, interior decoration will begin to fall off, mold and mildew will appear. Staying in such an apartment will not only be uncomfortable, but also unsafe, especially for children. After all, they are most susceptible to the occurrence of diseases caused by.

What to do in such a situation? Many people try to install additional heating radiators, but this, most often, does not solve the problem or solves it, but not completely. Dampness moves to the ceiling, forming places where mold accumulates.

What is the right thing to do in such a situation? The best solution is that you need to try to insulate the walls. How can I do that? How to do it? We'll try to figure it out now. What is the best way to insulate the walls of an apartment from the inside? First, let's look at what types exist.

Today, the market for thermal insulation materials is extensive, represented by various products. All of them are divided according to the place of their installation: outside the wall or inside the room.

Each of them has both disadvantages and advantages. When installing any of them, you must strictly follow the manufacturer's instructions.

When buying a heat insulator, you should pay attention to the following parameters:

• heat conductivity;
• air permeability;
• waterproofing properties;
• environmental Safety;
• fire resistance;
• operating time.

Using high-quality material, you can insulate a corner without any problems. Which one is best insulation will do for walls inside the apartment? What is the best way to insulate walls from the inside?

Minvata

This heat insulator is the most popular; it is made from basalt fiber. He has wonderful thermal insulation properties, admits good ventilation air, but does not tolerate excess moisture well. This material has a high degree of fire safety and does not emit toxic substances when exposed to direct fire.

When installing mineral wool, special guides are used, and the installation process itself does not require much effort, since the material is light and elastic. Is it possible to insulate walls with it? But over time, these qualities can cause it to lose its shape.

The environmental component is also ambiguous - the material emits a small amount of harmful gases. Some people do not use it because of the significant weight gained during installation of the structure.

Polystyrene foam insulation

The name speaks about the process of its creation. That is, the material is created by foaming polystyrene under high pressure. The price of such material is quite affordable, it is easy to assemble and install, which makes it a popular heat insulator.

It has good thermal insulation properties, it is environmentally friendly and safe. It can be used for interior work, and for external ones. It can be mounted on walls made of any material.

The process is quite simple and not labor-intensive. The advantages include its huge service life. But of course there are also disadvantages.

So, due to poor water permeability, on wooden walls Condensation can accumulate, which leads to their destruction, and it is also highly flammable. The insulation of a concrete wall from the inside can be carried out perfectly using this material.

Extruded polystyrene foam

This material is the most popular insulation. It is elastic and easy to process. The disadvantages include the difficulty in joining sheets.

There is a material on sale in which the edge is made in the form of protrusions, which makes it much easier installation work.

has good moisture resistance, it is lightweight, convenient for installation work.

Use of polystyrene foam

This is an excellent material for insulating apartment walls. It contains more than 95% gas, so it is an excellent heat insulator.

It is distinguished by its low cost, excellent waterproofing, and fire safety. Polystyrene foam is used at any temperature, being an environmentally friendly material.

Application of keramoizol

It's relative new material. It is sold in containers of various sizes, as it represents liquid material. Has excellent thermal insulation properties. Keramoizol is a durable, waterproof and vapor-tight product.

During installation, several layers are applied, and for better thermal insulation- six. The layers are laid perpendicular to each other. This material has proven itself only with the best side.Its only and main disadvantage is its high price.

Penoizol insulation

Thermal insulation material - penoizol is a type of polyurethane and is used in the form of foam. The advantage is quick installation material in brick construction., forming a layer required thickness heat insulator, no seams or joints.

Excellent thermal insulation and waterproofing properties, the material is non-flammable and environmentally friendly. But perhaps its main advantage is the low cost of work, almost two times less than when using conventional materials.

Using Astratek

Asstratek is a suspension; solid particles are represented by various polymers. To apply to the wall, use a spray gun or install it manually paint brush. Excellent insulation, just one centimeter of layer is similar to fifty centimeters of a mineral wool slab.

Does not take up the interior space of the room, forms a smooth, uniform surface that requires minimal processing for applying the cladding. The main limiting factor for large-scale application is its high cost.

How to insulate the walls in an apartment from the inside? It's up to you to decide.

How to insulate walls in a panel and monolithic house?

How to insulate walls from the inside? How to insulate concrete wall from the inside? How to do this correctly? To insulate a wall from the inside, we will consider step-by-step instructions for insulating walls and partitions in a panel house from the inside.

Algorithm of actions:

• First you need to prepare the walls. To do this, you need to remove furniture, clean the walls from finishing material to plaster. Therefore, this procedure should be combined with renovation work in your apartment;
• next must be done. It is best to use special polymers, but you can also use regular ones. plastic film. It is applied directly to the walls, the places where the strips are fastened are glued. To do this, use construction tape;
• Next we install the sheathing; you can use both wooden and metal guides. In the first case, the tree must be treated with antiseptics and fire-fighting solutions. When installing the sheathing, the step size must be selected depending on the insulation, so as not to form gaps and voids;
• then we directly lay the heat insulator, that is, we insulate the walls. It should fit into the openings between the sheathing. Many materials are designed in such a way that during installation they straighten out and fill the entire form, this significantly reduces installation time;
• installation . By installing it, we protect our insulation from wet steam, which is always present in the apartment. Under no circumstances should these measures be neglected, as moisture will begin to accumulate in the insulation. As a result of this, the product will lose its properties, and all your work will be lost.

The vapor barrier film is laid without gaps or omissions, the joints and cracks are treated with sealants;

• installation . It is necessary to choose a material suitable for installation in residential premises. When installing sheets, it is important to follow the instructions, and then you should do the necessary procedures for installing facing materials.

How to insulate the walls of an apartment from the inside? You can insulate a corner apartment in a panel or monolithic house by following these six steps.

Installing insulation on brick walls

How to insulate brick walls inside an apartment with your own hands? Corner walls V brick house can be insulated using the same method as in a panel one. Therefore, we will analyze the work of installing material made from polystyrene.

Insulating a wall in an apartment from the inside:

• clean the walls down to the plaster. If it is missing, then it should be applied. After this, the walls must be leveled, cracks repaired and then treated with a primer;
• you need to prepare the glue according to the manufacturer's recommendations and apply it to the walls that you will insulate. In the beginning, you can use a regular spatula. You need to apply glue to the walls, then take a notched trowel and go around the entire perimeter again. This is done in order to create uneven surface glue. This promotes better adhesion of the insulation;
• how to insulate a wall in a corner apartment from the inside? Next, we take sheets of thermal insulation and begin installing them on the walls. First of all, the very bottom row is laid. We apply the polystyrene sheet tightly and press it through; you do not need to use dowels or other fastening materials. When installing, use a level and carefully join the edges so that no gaps form; if necessary, cut the sheets. The next row is installed so that the junction of the two sheets is in the middle of the bottom sheet. This will give greater durability to the entire structure.

Watch the surface of the insulation so that no unevenness is formed, because this will bring additional difficulties during final finishing.

• After you have installed the thermal insulation, you can begin finishing work. If you plan to cover the walls with plasterboard, then some additional work over insulation is not required. If you plan to cover it with a layer of plaster, putty, wallpaper, or paint, then you need to treat it with a primer, then install a mesh of reinforcing fiber. After this, you can begin to apply layers of plaster or putty.

By following these steps, you can insulate corner room from the inside.

Insulation of walls using the “electric floor” method

How to insulate a wall in an apartment from the inside according to this method? Insulation of the apartment from the inside is carried out as follows. First of all, you need to attach the “” sheets to the wall using fastening materials.

After this, we connect the sheets to electrical network apartments. In the most severe frost, we turn on the system and warm up the walls until they are completely dry. After this, we lay thermal insulation to prevent heat loss. Then you can start tiling the walls.

So, if you decide to insulate the walls of a corner apartment, you need to choose a material based on the type of walls and the price range of the heat insulator. Then it is important to consider the method of installation and subsequent cladding.

You should also pay attention to the following aspects:

• installing insulation reduces the volume of the room;
• poorly performed work can lead to mold;
• For a comfortable life it is necessary to install ventilation.

By strictly adhering to the rules, you can insulate your apartment and create comfort in it. Insulating the walls of an apartment from the inside is a fairly simple process.

AND inside(you can insulate the front, rear, end wall) is carried out according to the instructions. An insulated corner apartment is great because you can enjoy comfort.

During the operation of residential premises in apartments or houses, situations arise when spaces are formed between the wall and the floor different sizes and depth. There is a need to seal them, but not only because they spoil the appearance of the living space, but also because this is a direct source of drafts, the penetration of dampness into the rooms, which brings with it hordes of insects, mold and mold.

Therefore, it is extremely important to immediately begin to eliminate it after identifying such a problem. Carrying out the work will not take much effort and time; it involves following several stages:

• Determining the size of the gap - length and depth;
• Based on the scale of future work, the material with which the hole will be sealed is selected.

To seal very small cracks (about 1 cm), you can use mortars of putty, mounting plaster or cement. Larger gaps (2-5 cm) must be filled with polyurethane foam. If the damage is much larger (5 cm or more), then you need to resort to more serious work and use other materials. Below is a consistent technology for eliminating gaps between a wall and a floor of any complexity.

Preparation for work

Sealing such cracks falls into the category cosmetic repairs. Preparation depends on what decorative elements your walls or floor are decorated with. If there is a baseboard, it must be removed, the wallpaper removed, the paint layer cleaned and removed, and the whitewash washed off. In the latter case, you need to let the wall dry completely. Remove all dust and dirt that may interfere with the quality fixation of the sealing materials.

If the installation takes place in a room where you do not plan to carry out complete renovation, then the wallpaper needs to be removed only partially, or try to carefully tear off the strip from the wall so that after finishing the work you can glue it back, returning the wall to its original appearance. All surfaces that may get dirt during the repair process must be protected with film, paper and secured securely - this will avoid additional costs when putting things in order. Such measures will protect the floor and walls from polyurethane foam, plaster and paint. Paper or newspapers should not be used if there will be a lot of water in the workplace - they are useless as a protective material in this case.

The goal is a large gap

To fill the hole, the ideal option would be suitable sized pieces of brick, polystyrene foam, polystyrene foam or plastic. If the parts are large, then they need to be broken or broken - small filling components guarantee that they will fit inside the hole as tightly as possible and thoroughly fill the cavity. Be careful that when filling the gap, you do not deform the existing hole or expand it.

These materials will help you save expensive mounting foam, which should be poured into the gap after the previous materials. Practice shows that using bricks or other fillers, only one container of polyurethane foam is required to restore even very large damage.

You should not fill it to capacity, because it tends to expand several times. Fill the remaining space by about a third, in very severe cases - by half. If the layer turns out to be very large, then apply it not at once, but in parts, allowing the previous layer to completely expand and harden. This will reduce the risk of overfilling and subsequent falling out of rags of foam, and as a result, will save its volume.

The target is a medium or small slit

The ideal option for filling such holes would be soft, plastic materials with high density - tow or construction felt. To prevent such materials from becoming a haven for insect pests, before filling they must be thoroughly impregnated with insecticidal substances, most often formaldehyde.

The material is rolled into small rolls, the diameter of which should be slightly larger size crack, and is applied to the crack. Next, using a small rubber or wooden hammer, the roll is carefully but confidently driven into the hollow space of the damage. It is advisable to fill the void with a single piece of material, without small parts, so that unnecessary cavities do not form between them.

If the gap is so small that you physically cannot drive tow in there, then a soft spatula and a plastic gypsum mortar will come to the rescue. The technology is simple - apply a strip of plaster to the tip of the spatula and apply it to the damage, then gently press. This will allow the mortar to fill the entire cavity and immediately finish the wall surface to minimize finishing preparation.

To protect the surrounding area from dirt, you can use self-adhesive construction fabric (which will not work if you already have wallpaper) or the above methods. After the gap is completely clogged, the formaldehyde dries - you can decorate the seam.

The gap between the baseboard and the wall or floor

It usually forms when old walls become warped or wooden baseboards dry out. Such an error can be repaired very simply - using acrylic sealant; modern stores provide a choice of any colors and shades. The cylinder is installed in special device for supplying sealant and is applied over the distance between the elements.

Rules for working with polyurethane foam

Two thirds of cases still require the active use of polyurethane foam, even in small quantities. Therefore, it is important to figure out how to use it correctly. The recommendations are:

• Before filling the cavity, its surface must be slightly moistened with ordinary water. To do this, it is advisable to use a mechanical spray bottle or a bottle with holes in the lid. This is done to better fix the foam inside the damage.
• When filling, be aware of the foam's ability to expand. In addition, moisturizing the surface will only enhance this effect. The foam must be applied carefully, carefully, little by little.
• Ideal working conditions with it are from five to twenty-five degrees Celsius. The cylinder must be heated in water at the appropriate temperature.
• Before use, the container with foam should be shaken thoroughly.
• Carry out work only with protective glasses and gloves - the foam is very caustic and firmly sticks to all things and objects. In case of accidental contact with finishing surfaces, it is recommended to remove foam only after complete drying; wipe off foam that has not yet hardened with a special solvent.
• Hardened foam is removed with a sharp knife.

Finishing the wall after repairing the damage

Excess foam should be removed so that a small depression remains at the seam site. It will be filled with a small layer of putty or plaster using a spatula and brought to the same level as the wall. After the layer of mortar has dried, not a trace will remain of the gap. The top of the wall can be finished in all sorts of ways - attaching a plinth, painting, adding wallpaper, finishing with tiles, plastic, wood, and so on.

Conclusion

It is advisable to detect such damage between the floor and walls and repair it before starting finishing works so as not to damage existing finishing surfaces during work. Thus, the work will be completed faster and at lower cost. If the sealing takes place in the finishing room, then precautions should not be neglected, especially when working with polyurethane foam.

Video

From the video you will learn in more detail how and with what to seal cracks.

The thermal insulation properties of concrete panel houses leave much to be desired, since they are very hot in summer and cold in winter, which leads to increased energy costs for heating. This problem can be solved by thermal insulation of the walls, however, this issue must be approached competently. Therefore, next I will tell you how to properly insulate a panel house.

Insulation options

Thermal insulation of a panel house implies, first of all, insulation of the walls. Moreover, it is advisable to perform this operation outside, in which case the walls will be really warm. If this is not possible, for example, if you do not have permission to change appearance facade or an apartment is adjacent to an unheated room that cannot be insulated (elevator shaft, entrance, etc.), then insulation can be done from the inside.

In all other cases, it is better to refuse internal insulation for the following reasons:

• internal insulation takes away useful space in the apartment;
• after thermal insulation, the walls stop heating altogether, which can lead to the formation of cracks;
• forms on the surface, which can lead to the formation of mold;
• there is no possibility of insulating the ceiling, which is adjacent to the cold walls and serves as a cold bridge.

Thus, insulating walls from the inside can only be considered as extreme case. However, below I will talk about the nuances of thermal insulation in both cases.

External insulation

First of all, let's look at how to insulate walls from the outside. This process can be divided into several stages:

It must be said that almost every stage contains its own nuances, on which the final result depends. Therefore, all work must be performed with special responsibility, from beginning to end.

Preparation of materials

First of all, you need to decide on the insulation. For these purposes, the following materials are most often used:

• expanded polystyrene (foam) is a fairly cheap and lightweight material. Disadvantages include fire hazard. It should be noted that for external insulation, foam plastic with a density of at least 18 kg/m3 can be used;

• mineral wool is an environmentally friendly and more durable material that resists the combustion process. The disadvantages of mineral wool include its higher price, as well as the inconvenience of working with it - if it gets on the skin, mineral wool fibers cause irritation.

The density of mineral wool for facade insulation must be at least 85 kg/m3.

The thickness of the insulation must be at least 100 mm. In northern regions, it is better to use 150 mm thick insulation.

In addition to insulation, you will also need the following materials:

• adhesive for insulation - as a rule, it is selected depending on the type of thermal insulation material, however, there are also universal compositions;
• inter-seam insulation for panel houses - most often polyurethane foam is used for these purposes;
• plastic umbrella dowels;
• universal primer;
• fiberglass reinforcement mesh;
• aluminum perforated corners;
• decorative facade plaster;
• facade paint.

Preparing the walls

So, before you insulate the walls from the outside, they need to be prepared. This is done as follows:

1. start by removing the old coating. As a rule, panel houses are covered with tiles, which begin to lag over time. In this case, the tile must be dismantled;
2. then the surface of the walls should be cleaned of dust and dirt;
3. Next you need to insulate the seams. Often, in order to insulate joints in panel houses, they must first be expanded.
   After this, be sure to clean them from dust and moisten them. The prepared seams should be filled with polyurethane foam. You can also use putty for these purposes;
4. After the foam hardens, it must be cut off so that it does not protrude above the surface of the walls.

If work needs to be done at height, it is better to entrust it to specialists who have all the necessary climbing equipment.

After preparing the walls, you can begin installing the insulation.

Installation of insulation

Insulation installation instructions are as follows:

1. First of all, you need to dilute the glue in water and mix it thoroughly. How this is done is indicated on the packaging with the composition;
2. then the glue must be applied to the insulation using a notched trowel. If the surface of the walls is uneven, it is better to apply the glue in lumps, which will allow you to adjust the position of the insulation relative to the wall;

1. Now the insulation needs to be glued to the wall. Start working from the corner, performing installation in rows from bottom to top, and thermal insulation should be positioned so that the ceiling is also insulated.
   To glue the insulation, press it against the wall and check the position with a building level;
2. then glue the insulation on the opposite side in exactly the same way, and stretch the twine along the first row. The stretched thread will serve as a beacon for the remaining thermal insulation slabs;
3. then glue the remaining insulation boards of the first row along the lighthouse;
4. then the second row of insulation is installed according to the same scheme. The only thing is to position it offset relative to the first row, i.e. according to the principle of brickwork.
   If you are insulating a corner room from the outside, then it is also necessary to ensure that the insulation is bandaged at the corner, as shown in the diagram below;

1. According to this principle, the entire surface of the walls is insulated;
2. Now you need to install the dowels. To do this, drill holes directly through the insulation to the required depth, then insert “umbrellas” into them and drive in the expansion pins. Keep in mind that the dowel heads should be slightly recessed into the insulation.

Pay special attention to the location of the dowels - they should be installed between the joints of the insulation at the corners, as well as one - two dowels in the center of each insulation;

1. To complete the work, it is necessary to paste over the window openings. To do this, cut the insulation into panels about 3 cm thick and glue them around the perimeter, thus creating slopes.

To cut the insulation, use a regular wood saw.

This completes the insulation installation process.

Preparation for reinforcement

Before proceeding with reinforcement, it is necessary to prepare the surface of the thermal insulation by performing the following steps:

1. use the long rule by applying it to the walls in different areas. If lumps are found, they must be rubbed with a special grater.;
2. also on at this stage make sure that all dowels are recessed into the insulation, otherwise they need to be finished off. If it is not possible to deepen the dowel, it must be cut off with a mounting knife and a new one installed next to it;
3. then glue the perforated aluminum corners on all external corners and slopes, using the same glue for insulation;
4. if there are gaps between the insulation boards, they must be filled with small pieces of thermal insulation or special foam;
5. To complete the work, apply glue to the heads of the screws, as well as the joints of the insulation boards.

The result should be a smooth wall surface that can be plastered.

Reinforcement

Insulation reinforcement is carried out as follows:

1. start work with slope reinforcement. To do this, cut the mesh into sheets of the required sizes, taking into account that it should be placed with a turn at the corners and an overlap of about 10 cm;
2. after that, apply glue to the surface of the slope a few millimeters thick and attach the mesh to it. You need to run a spatula across the canvas so that the mesh sinks into the glue. Do the work as carefully as possible so that the end result is smooth surface ;
3. after the surface has dried, the glue is applied again and carefully leveled with a spatula, as if you were puttingty;
4. Now the walls should be reinforced using the same principle. As a result, you should have a smooth surface suitable for applying decorative plaster.

Padding

Before covering the facade with decorative plaster, the surface of the walls should be treated with a primer. This is done like this:

1. shake the façade thoroughly and pour it into a special tray for a paint roller;
2. then dip the roller into the tray and apply it to the wall. Try to do the work carefully so that there are no soil drips;
3. After the surface has dried, the primer must be applied again.

Now you can start applying decorative plaster.

Plaster

Decorative plaster is applied very simply and quickly:

1. First, dilute the mixture in water and stir. Detailed instructions are available on the packaging;
2. Next, use a narrow roller to roll the plaster onto a small trowel or a wide spatula and apply it to the wall in an even, thin layer. The thickness of the layer depends on the size of the filler fraction;
3. When the plaster on the wall begins to set (thicken), the surface needs to be rubbed with trowel to give it a certain texture. Malka can make circular or reciprocating movements in a vertical or horizontal position;
4. According to this principle, the entire prepared surface of the facade is covered.

Apply within one wall decorative plaster necessary in one go, i.e. without interruption. Otherwise, the transition border will be noticeable.

Painting

The final stage of work is painting, which is carried out as follows:

1. The paint needs to be shaken and, if necessary, tinted. You can find out in detail how coloring is performed on our portal;
2. after this, paint must be poured into the roller tray and the roller itself must be dipped into it;
3. now apply the coating in a uniform thin layer, avoiding its spreading and splashing;
4. hard-to-reach places should be touched up with a paint brush;
5. After a few hours, when the paint has dried, the procedure must be repeated again.

At this point, the work on external wall insulation is completed.

Internal insulation

Insulation from the inside can include not only thermal insulation of walls, but also floors and even ceilings. Therefore, next we will consider the nuances of insulation of all these surfaces.

Floor insulation

To insulate the floor you will have to concrete screed on top of the insulation. This work is carried out in the following sequence:

1. first of all, prepare the floor - clear it of debris, if necessary, remove the finishing coating;
2. then cover the floor with waterproofing film, placing the sheets overlapping and folding over the walls;
3. Then thermal insulation is laid on top of the waterproofing. This can be either mineral wool or polystyrene foam;
4. then another layer of waterproofing film should be laid on top of the thermal insulation. To ensure maximum tightness, seal the joints with tape.;
5. Now you need to pour the screed on top of the insulation according to the standard scheme. The only thing is that you should not use reinforcing mesh so as not to damage the waterproofing. It is better to perform reinforcement by adding special fiber to the solution.

If you don’t want to deal with wet work, you can do a dry screed yourself. To do this, cover the floor with a layer of expanded clay, level it along the beacons, and lay special panels for dry screed on top.

Wall insulation

It is best to insulate a cold wall from the inside using a dry method. This operation will be performed in the following sequence:

1. First of all, prepare the wall for insulation - clean it from old decoration, if necessary, seal the cracks with putty. In addition, be sure to treat the surface with an antiseptic to prevent mold;
2. A vapor barrier film must be attached to the prepared wall. To do this, you can use screws with wide heads or even wooden slats;
3. Now you need to mount a frame for attaching drywall or other finishing material (plastic panels, lining, etc.). To do this, as usual, attach the guides to the floor and ceiling, and the distance from them to the wall should be a centimeter greater than the thickness of the insulation;
4. then insert the posts into the guides and secure them with brackets. At this stage, check the position of the racks with a building level. The distance between the racks should be such that the insulation fits closely into the space between them, leaving no gaps;

1. Next, the space in the resulting frame needs to be filled with insulation. The latter should fit tightly not only to the racks, but also to the ceiling and floor;
2. Now you need to attach another layer of vapor barrier film to the frame. To do this, you can use profiles that are attached to the frame with self-tapping screws;
3. At the end of the work, attach it to the frame using self-tapping screws finishing material. On our portal you can find detailed information about how to install drywall, plastic panels and other finishing materials.

If you want to completely insulate the room, you need to place thermal insulation on the ceiling. The installation principle remains the same, with the only difference being that the frame is attached to the ceiling, not the walls.

If your apartment has a balcony or loggia, the room can also be insulated and even heated. In this case you can use extra space as residential.

Before insulating a balcony in a panel house, all surfaces must be treated with an antifungal compound, since mold often appears here.
