Wall insulation from the inside of the apartment. Wall insulation from the inside in a corner apartment. We will reveal the secret of what is happening inside the insulated walls

Many would probably like to know how to insulate an apartment with their own hands. Old Soviet-built houses are mostly poorly insulated. The central heating systems are very worn out. About how to properly perform such work, and we will talk later in the article.

Stages of warming

How to prepare an apartment for winter? The order of work in this case should be as follows:

Insulation of windows and doors.
Replacement of old heating radiators.
Wall insulation.
Insulation of the ceiling and floor.
Device effective ventilation.

So, let's figure out how to insulate an apartment, in more detail.

Window insulation with rubber bands

The answer to the question of how to insulate an apartment depends, among other things, on how tight the windows are in it. Of course, dry wooden structures it is best to replace with new plastic ones. However, sometimes it happens that the funds for this are not enough. In this case, you will have to insulate the old windows. How to do it right? There are several methods for isolating such structures:

Use of rubber seals.
Seal gaps between frames.
Sticking with strips of fabric, paper or tape.

Rubber seals are sold in hardware stores and are narrow tapes made of foam rubber or one of the varieties of soft polymer. Warming with their help is extremely simple. The tape is attached to the frame by means of an adhesive layer on it. When performing this procedure, you need to try not to stretch the material.

caulk insulation

Having wondered how to insulate the apartment inside, you should also pay attention to the gaps between the frames and the opening. Sometimes they are very wide. Using a sealant in this case may not help. Large gaps are best sealed. To do this, you can use rags, pieces of foam rubber, or even just paper. On top of the caulk, all surfaces should be sealed with masking tape or tape.

Use of putty for sealing windows

There is another answer to the question of how to properly insulate an apartment by sealing windows. You can close the gaps using putties specially designed for this. Such mixtures are applied using B Lately often used to insulate windows transparent sealants. The technology of insulation in this case is no different from the method of insulation with ordinary alabaster putty. In the event that the sealant accidentally gets on the glass, it is not necessary to wash it. Remove it with a sharp blade after solidification.

Replacement of heating radiators

It is also cold in high-rise buildings due to the low efficiency of old heating radiators. Therefore, having wondered how to insulate an apartment, of course, you should also think about replacing them. Do this in the warm season, before the start of the heating season. The order of work in this case is as follows:

Cut off old radiators.
Marking is done on the wall, brackets are nailed.
The new battery is hung on the wall. Nuts included in the kit are screwed onto all its four outlet pipes.
Further, inlet and outlet taps are screwed to two of them (diagonally at the top and bottom), with tow winding and thread coating with paste.
Opposite the first, on the back of the radiator, a Mayevsky crane is installed.
The remaining branch pipe is closed with a special plug.

The method of connecting radiators described above is called diagonal. There are also side and bottom mounts. In the first case, both taps - both inlet and outlet - are screwed on one side of the battery, at the top and bottom. The air release device and the plug, respectively, are installed on the other. When connecting to the bottom, both valves are attached to the right and left to the lower branch pipes. The Mayevsky crane is always installed opposite the element supplying the coolant.

How to increase the efficiency of heating batteries

How to insulate an apartment with your own hands by replacing heating radiators, you now know. Here are some tips on how to make their work more efficient. So:

If it is cold in your apartment, in no case should you cover the batteries with decorative panels.
When radiators are placed in too deep niches under the windows, they will heat much worse.
The battery should be about 5 cm from the wall, and not less than 10 cm from the floor and window sill.

Wall insulation with mineral wool

Thus, we have considered how to insulate an apartment from the inside by closing windows and balcony door and replacement of heating radiators. Next, consider how to properly insulate walls. This procedure consists of several stages:

The walls are thoroughly cleaned of dust and dirt.
The crate is mounted under the drywall sheets. The easiest way to make it is from a beam of width corresponding to the thickness of the insulation.
Between the purlins, mineral wool slabs are inserted by surprise.
Further, they are additionally fixed to the wall with dowels - "fungi".
On top of the mounted insulation boards, it is stretched. Unfortunately, it is located inside the walls themselves when insulating the room from the inside. Therefore, the insulating material must be carefully protected against the formation of condensation on it. For this purpose, vapor barriers are used. It can be an ordinary thick polyethylene film or some of its modern substitutes. The vapor barrier strips are fixed horizontally, starting from the bottom. Fix them to the crate with thin bars.
Next, drywall sheets are mounted on the resulting counter-lattice.
At the final stage, the walls are painted or wallpapered.

Surface insulation with polystyrene foam

There is another answer to the question of how to insulate an apartment from the inside by lining the walls. This can be done with rigid polystyrene foam boards. The walls are also thoroughly cleaned, degreased and primed. Then they are glued on. In this case, special adhesives designed for foam plastics are used. In this case, the crate is not stuffed. Plates are fixed to the wall apart. Begin installation from the bottom - from the floor. At the corners of the slab, cut to the required width with a sharp knife. In addition to the walls, they are fixed with “fungus” dowels. Next, seal all joints with white mounting foam. After that, the surface of the walls is covered with a special adhesive, into which the reinforcing is pressed. At the final stage, the walls are finished with decorative or ordinary plaster.

Use of Styrofoam

Sometimes the insulation of apartments is carried out with foam. This material has a low degree of thermal conductivity and is very inexpensive. The answer to the question of how to insulate an apartment with foam plastic is also not too complicated. The procedure for performing work in this case is exactly the same as when insulating surfaces with polystyrene foam. The only thing is that you need to handle foam sheets as carefully as possible. The problem is that they can be broken very easily.

How to insulate the ceiling

Of course, the answer to the question of how to effectively insulate an apartment inside also depends on how well it can hold. This is especially true for apartments located on the top floors. The method is absolutely no different from the wall insulation method. The only thing - in this case, you need to pay maximum attention to fixing the plates to the surface. If you can not use dowels-"fungi" when insulating the walls, then when installing the insulator to the ceiling, their use is considered mandatory. Otherwise, the plates will simply fall.

How to insulate the floor

The question of how to insulate an apartment with your own hands, if it is located on the ground floor, also comes down to how to isolate the floors. To do this, first remove the fine finish. Next, remove the old boards. The opened logs must be smeared with antifungal and refractory compounds that increase the refractory properties of wood. Then, insulation boards are laid between them. In this case, you can use both mineral wool and polystyrene foam or expanded polystyrene. The thickness of the insulation should be slightly less than the width of the lag. This is necessary so that eventually a ventilation gap remains between it and the new floorboard. At the next stage, a vapor barrier is mounted on top of the insulation. Attach it to the logs on thin slats (two on each side). Next, proceed to stuffing the board.

In the event that you wondered how to insulate a corner apartment, wall, floor and ceiling insulation would be the best answer to it. The fact is that in such premises the structures freeze through much more than in ordinary ones. This is especially true for corners.

Ventilation device

So how do you insulate cold apartment you now know. However, after the walls, floor and ceiling are insulated, the room may become stuffy and damp. Therefore, at the final stage, you should definitely take care of the device for effective ventilation. by the most simple option there will be a purchase of a ready-made system. However, such equipment is very expensive. Therefore, in a standard small apartment, you can use a slightly different ventilation method. To do this, before installing the insulation in the outer walls under the windows, holes are drilled with a diameter of about 10 cm. Exactly the same will need to be done in the “pie” of the wall insulation.

It is very easy to check the correct operation of the common house ventilation shaft. To do this, you will need to bring a lit lighter to the grates in the kitchen and toilet. If the flame begins to noticeably deviate from the vertical axis, then everything is in order. The ventilation is working properly. If this does not happen, you will have to contact the management company and call specialists for verification.

We hope that now you more or less understand how to insulate an apartment in a high-rise building with your own hands correctly. Having completed all the activities described above, you can make your home as comfortable as possible for living in the cold season.

How to insulate an apartment from the outside

Since the method of isolation from the outside is considered much more effective, despite the complexity of implementation, sometimes it is also used for insulation. However, such a procedure can be carried out independently only when the apartment is located on the first or, in extreme cases, on the second floor. To isolate the premises located above, you will have to call specialists. Next, consider how to insulate an apartment from the outside in stages:

First of all, a crate is stuffed on the walls.
Further, heat insulator plates are inserted between the bars.
The walls are covered with a waterproofing film fastened to the bars.
Siding in progress.

When installing insulation boards, it is very important to make sure that they cover all joints around the perimeter of the apartment.

Insulation of the apartment from the inside most often becomes necessary in houses with panel walls, since they are not thick enough, they quickly cool down, the heating system cannot fully cope with its tasks, and the temperature in the rooms drops. How to insulate a wall inside an apartment, and what methods and materials to use - this question confronts most homeowners in concrete high-rise buildings. External walls in such houses become cold especially quickly, and often, due to temperature changes, they begin to dampen and become covered with mold.

Sometimes, when there is such an opportunity, the thermal insulation of the walls is carried out from the outside, as this — more effective method keeping warm. However, this option is very expensive due to the complexity of its implementation, and it is impossible to carry out such events on your own, without the use of special equipment, if the apartment is located above the first or second floor. Therefore, a decision is made to insulate the walls from the inside, to the detriment of the total usable area. But be that as it may, a warm apartment of a slightly smaller area is better than large cold rooms. Internal work may well be carried out with your own hands, without the involvement of specialists. The main thing is to choose the right material and have the right tools.

If the apartment has equipment autonomous heating, then wall insulation will help save energy resources, which are very expensive today.

Disadvantages of internal insulation

Compared with the external thermal insulation of walls, the internal insulation of the apartment has its rather significant drawbacks:

An insulated wall does not accumulate or retain heat, and heat losses range from 8 to 15%.

With internal insulation, the “dew point” may be inside the insulation, which leads to dampness

The “dew point” for internal thermal insulation is between the insulation and the wall, sometimes inside the insulation layer. This leads to the formation of condensation and the appearance of mold colonies. .
An improperly insulated wall from the inside will freeze all the time, and this inevitably causes irreversible destructive processes in the thickness of the material over time.

Proper insulation

So that condensation does not form under the thermal insulation layer from temperature changes in the winter, and also, as a result, mold spots do not appear on the walls, you must carefully follow all the technological recommendations for warming concrete walls from inside the apartment.

An important element in the structure of the thermal insulation "pie" is a high-quality vapor barrier. It should protect the insulation from moisture penetration, which will allow the entire structure to effectively perform its functions for a long time.

What work needs to be done to achieve the goal?

You need to purchase a vapor barrier film High Quality and waterproof adhesive tape for sealing the seams on the connection of its sheets.
For the insulation layer, you need to choose a material that has low vapor permeability. It is desirable that this indicator be lower than the vapor permeability of the wall material. In this case, moisture evaporation will occur towards the street, and not inside the apartment.
When gluing the insulation, its surface is completely smeared with glue using spatula-comb, and it is pressed very tightly against the surface of the wall, so that even small cavities do not remain between them.
In order to avoid the occurrence of excessively high relative humidity inside the premises, they must be equipped with additional ventilation of a natural or forced type. For example, for this window frames install valves through which air will enter the room.

Next, you need to accurately calculate the required thickness of the insulation. It will depend on the average daily temperature in the region in winter. The thickness of the thermal insulation material should not be less than those parameters that were obtained during the calculations, otherwise the steam-thermal balance will be violated.
Before installing the insulation system, the walls must be treated with special primers. They will "treat" the wall, will not allow mold colonies to form on it, and will also increase adhesion when gluing thermal insulation.
Installation of insulation can only be started after the wall has completely dried.
It is impossible to allow the formation of "cold bridges", which can nullify the entire insulation process. The risk of their occurrence is especially high at the junctions of walls and ceilings.

What heaters and how are they used

Cork - excellent natural material for thermal insulation

Such a thermal insulator is made in the form of plates or rolls from the bark of a special variety of oak - cork. Therefore, it is an environmentally friendly safe insulation, which is very important for interior decoration.

Using high quality material, you can solve three problems at once - these are noise and sound insulation, as well as decorative wall decoration.

An important condition for the installation of the cork coating is the evenness of the wall, therefore, before proceeding with its gluing, it is necessary to carefully prepare the surface. This process is carried out as follows:

The old coating is completely peeled off the wall.
Then the entire surface is treated, which will protect the wall from damage by fungus or mold.

The next step is to level the surface.
You can ennoble the walls with drywall, but in this case, the sheet must be completely smeared with waterproof glue or mounting foam, so that there are no voids under it. Drywall is firmly pressed against the wall and additionally fixed with anchors or plastic "fungi".
Cork material can be glued onto a dried wall. To do this, use a special glue designed for such purposes.

The positive qualities of the material, in addition to its environmental friendliness, low thermal conductivity and good noise absorption include:

Ease of installation of cork wall covering while maintaining accuracy in work.
Aesthetically attractive respectable look.
Always warm and pleasant to the touch surface of the material.
A variety of release forms, textured patterns and shades.

Cork is not only an excellent thermal insulator. It will give the room a special decorative effect.

Cork insulation does not have a large thickness, therefore it does not make the area of the room smaller - this quality compares favorably with other thermal insulation materials.

Penofol

Penofol, in its essence, is a rolled foamed polyethylene with a thickness of 2 to 10 mm, on one side of which it is applied, which contributes to the reflection of heat into the room.

Penofol - foamed polyethylene with a foil coating

Before its installation, the surface is prepared in the same way as for a cork coating.
Penofol can be fixed to even walls with the help of construction double-sided tape. Under any circumstances, the material is placed with the foil side into the room. This creates a kind of thermos for efficient heat retention.
stripes penofol are laid end to end. Between themselves, they are glued with a special adhesive tape, which also has a foil-coated reflective surface, since the entire coating must be airtight.

On top of the penofol fixed to the wall, a crate of slats, bars or galvanized metal profiles is installed. This frame with a tanet base for mounting lining or wall cladding with plasterboard sheets. The plasterboard surface can subsequently be covered with plaster, wallpapered, or carefully puttied and sanded, and then painted.
When installing drywall or lining, it is very important to leave a gap at the top and bottom of the structure, which will serve as a vent for air circulation so that moisture does not accumulate.

Despite its small thickness, penofol is an excellent heat and sound insulator. It is used as a separate insulation, but it can also be used in combination with other materials. It attracts with the simplicity and speed of installation on walls, floors or ceilings, as well as long term operation.

Thermal insulation materials

When choosing a material for insulating a dwelling from the inside, you must first examine all the surfaces of the walls on which thermal insulation will be installed. If the wall is dry and there are no mold spots on it, then you can start preparing the surface and purchase insulation material. It is strictly forbidden to carry out such work on an unprepared basis. Not only will such insulation not give the desired effect - you can thoroughly spoil the apartment atmosphere, make it damp, unhealthy, since spores of many types of mold or fungus are extremely dangerous for people's health, especially for those suffering from chronic respiratory diseases or a predisposition to allergic reactions. .

In general, any of the apartment methods presented in the publication from the inside will not require any complex additional equipment, and this one technological process you can do it on your own.

Most of the constructed panel and brick houses did not provide for the insulation of facades. Concrete and brick have high density and low thermal insulation properties. The result is cold walls and uncomfortable temperatures. There are several ways to insulate from the inside, the main thing is to avoid the appearance of dampness.

Dew point - physics of the phenomenon

A cold wall is not the only drawback of panel or brick houses. Often dampness and accompanying fungus and mold appear on it. The best way struggle - wall insulation from the outside (this is also a requirement of SNiP), but this is not always possible. Therefore, you have to fight the cold wall, insulating it from the inside. But there are pitfalls here.

Even if the cold wall was previously dry, then when it is insulated from the inside, dampness may appear. And the so-called dew point will be to blame.

The dew point is a conditional boundary at which the temperature of water vapor becomes equal to the temperature of condensate formation. It manifests itself, naturally, in the cold season. With proper design of the house (taking into account the characteristics of the region), it is approximately in the middle of the thickness of the facade of a material of uniform density.

If insulation is carried out from the outside, then the dew point shifts in the direction of decreasing density (that is, to the outer surface of the wall). When insulating from the inside, it moves inward, and condensate may appear on the surface of the main wall or inside the insulation.

And in order to assess the scale of possible damage, it is enough to say that as a result of the life of one person, about 4 liters of water evaporate per day (cooking, wet cleaning, personal hygiene, washing, etc.).

Features of cold wall insulation from the inside

There are several ways to prevent condensation on a wall insulated from the inside:

Creation of a layer of heat-insulating material with a vapor permeability lower than that of the facade material.
Warming with materials with minimal water absorption.
Application of ventilated facade technology (taking into account internal placement).

Liquid thermal insulation

polyurethane foam

PPU insulation meets all requirements for vapor barrier, water absorption and the absence of seams. Therefore, even if there is a dew point inside the layer, it will remain “conditional”, since there is no condensation in vapor-tight materials. It turns out from the side of the room a completely sealed heat-insulating layer.

The environmental friendliness of PPU after curing meets the requirements for residential premises. Harmful fumes are present only when the components are mixed during the spraying process - after polymerization, the structure of the material remains stable.

Thermal insulation is applied between the crate and sewn up with moisture-resistant sheet materials (GKL, OSB or plywood). In fact, it is like a large prefabricated sandwich panel.

The disadvantage of this method is the use of special equipment.

liquid ceramics

This is a relatively young heat-insulating material, the action of which is based on the use of two principles - the creation of a thin layer with high resistance to heat transfer and the reflection of heat towards the radiation source.

Of course, a thin heat-insulating layer cannot provide good thermal insulation - this is an auxiliary, but a mandatory factor. Although it gives a fairly high effect - the wall becomes much "warmer" to the touch.

The main task of reducing heat loss is performed by microscopic ceramic spheres that reflect infrared radiation.

According to the manufacturers, the effect of a 1.5 mm layer can be compared with thermal insulation with 5 cm thick foam plastic or 6.5 cm mineral wool.

Application method is the same as for acrylic paint(basic is the same). After polymerization, a dense and durable film is formed on the surface, and latex additives improve the waterproofing properties.

Roll thermal insulation

Penofol

Penofol is a combination of polyethylene foam with aluminum foil. This is a whole series of materials (including single-sided, double-sided, laminated, with an adhesive layer). Moreover, it can be used both in combination with other heat-insulating materials, and independently. By the way, penofol is popular for warming the bath from the inside, and there is much more steam there than in an ordinary residential area.

To insulate a cold wall, foam foam is used with one layer of foil (one-sided) and up to 5 mm thick.

In the case, as with liquid ceramics, the effect is achieved due to the low thermal conductivity of foamed polyethylene, as well as its low vapor permeability and high reflective properties of the foil (up to 97%).

But unlike seamless coatings, complete sealing and prevention of cold bridges cannot be achieved. Consequently, condensation may form on the surface of the foil. Even the obligatory sealing of joints with adhesive aluminum foil will still leave gaps inside between adjacent sheets.

The method of combating the formation of condensate on the foil is traditional - a crate with a ventilated gap between the foam and the outer lining.

polyph

Another version of polyethylene foam, but already made in the form of a kind of wallpaper - there is a layer of paper on both sides. Polyfoam and is designed for gluing wallpaper on it.

Of course, its thermal insulation properties are not as high as those of penofol, but to make a cold wall feel warmer to the touch, they are quite enough.

In most cases, the insignificant thickness of the insulation does not lead to the dew point moving to the inner surface.

The disadvantage of this method is that only a dry wall is insulated.

Insulation with expanded polystyrene

Expanded polystyrene (or extruded polystyrene foam) is glued to a prepared and leveled wall. Both materials have very low water absorption (especially extruded polystyrene foam), so the formation of condensate in the insulation layer is excluded. The main danger is its appearance on the surface of the insulated wall.

Therefore, it is best to glue sheets on special hydrophobic adhesive mixtures applied over the entire surface of the sheets. And to prevent the penetration of water vapor from the side of the room, treat the seams with sealant (you can also use foam plastic with a step or a tenon-groove connection).

Finishing can be done in two ways:

mesh reinforcement and plastering;
sheathing with panels on a supporting frame fixed to the floor, ceiling and adjoining walls (false plasterboard wall).

Warming with mineral wool

Mineral wool does not meet the requirements for vapor permeability and water absorption for insulation from the inside. But it can be used.

The main thing is to provide maximum protection from moist air from the side of the room and the weathering of water vapor from the insulation layer. That is, to perform a ventilated facade, but in the reverse order: wall, gap, vapor-permeable membrane, mineral wool, vapor barrier film, decorative cladding indoors.

It is necessary to create a false wall at a distance of 2-3 cm from the main wall. And to weather the water vapor from below and above, make ventilation holes.

If you have dealt with buying or selling apartments, then you have noticed that buyers are not very fond of corner apartments or rooms. What is it connected with? Although in summer such an apartment is much easier to ventilate, the view from the windows opens on two or even three sides.

But there is one significant downside. Very often, with the advent 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. Appears, the windows fog up, the floor becomes cold, and the bed is damp.

The main reason for this is the presence of three walls that have an exit to the outside, and therefore are most affected by low temperatures. In winter, even with central heating, the situation only gets worse.

Walls can freeze completely, especially in the corners, interior decoration starts to fall off, mold, fungus will appear. Being in such an apartment will not only be uncomfortable, but also not safe, especially for children. After all, they are most susceptible to the appearance of diseases, the cause of which is.

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

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

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

Each of them has both minuses and pluses. 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 conduction;
air permeability;
waterproofing properties;
environmental Safety;
fire resistance;
operating time.

Using high-quality material, you can easily insulate the corner. What is the best insulation for the walls inside the apartment? What is the best way to insulate walls from the inside?

mineral wool

This heat insulator is the most popular, it is made from basalt fiber. It has excellent thermal insulation properties, allows good air ventilation, but does not tolerate excessive moisture. This material has a high degree 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 material is light and elastic. Is it possible to insulate walls with them? But over time, because of these qualities, it can lose its shape.

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

Styrofoam insulation

The name speaks of 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 mount, 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 both indoor and outdoor work. It is mounted on walls made of any material.

The process is quite simple and labor-intensive. The pluses include its huge service life. But of course there are downsides.

So, due to poor water permeability, on wooden walls condensation may accumulate, which leads to their destruction, and it is also flammable. Insulation of a concrete wall from the inside is excellently carried out using this material.

Extruded polystyrene foam

This material is the most popular insulation. It is flexible and easy to work with. The disadvantages include the difficulty in joining the sheets.

There is a material on sale in which the edge is made in the form of protrusions, which greatly facilitates installation work.

has good moisture resistance, it is light, easy to install.

Use of Styrofoam

This great material for wall insulation. It contains more than 95% gas, so it is an excellent heat insulator.

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

The use of keramoizol

It's relative new material. It is sold in containers of various sizes, as it is liquid material. It has excellent thermal insulation properties. Keramoizol is a durable, waterproof and vapor-proof 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 from the best side. Its only and main disadvantage is the high price.

Penoizol insulation

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

Excellent heat-insulating 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

Astratek is a suspension, solid particles are represented by various polymers. For application to the wall, use an airbrush or mount it manually with a paint brush. Excellent insulation, just one centimeter of the layer is similar to fifty centimeters of mineral wool slab.

It does not take up the interior space of the room, forms a flat, homogeneous surface that needs minimal processing for cladding. The main deterrent to large-scale application is its high cost.

How to insulate the walls in the 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 a concrete wall from the inside? How to do it right? To insulate a wall from the inside, consider a step-by-step instruction for insulating walls and partitions in panel house from within.

Action algorithm:

First you need to prepare the walls. To do this, remove the furniture, clean the walls from the finishing material to the plaster. Therefore, this procedure should be combined with repair work in your apartment;
next to be done. It is best to use special polymers, but you can also use ordinary plastic wrap. It is applied directly to the walls, the bonding points of the strips are glued. To do this, use construction tape;
then we mount the crate, you can use both wooden and metal rails. In the first case, the tree must be treated with antiseptics and fire-fighting solutions. When installing the crate, 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 crate. Many materials are designed in such a way that when installed they straighten and fill the entire form, this significantly reduces installation time;
mounting . By installing it, we protect our insulation from wet steam, which is always present in the apartment. In no case should these measures be neglected, since moisture will begin to accumulate in the insulation. As a result, the product will lose its properties, and all your work will be lost.

The vapor barrier film is laid without gaps and gaps, 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 the apartment from the inside? Insulate a corner apartment in a panel or monolithic house You can by following these six steps.

Installation of insulation on brick walls

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

Wall insulation in the apartment from the inside:

clean the walls down to the plaster. If it is missing, then it should be applied. After that, 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. It is necessary to apply glue to them on the walls, then take a notched trowel and re-walk around the entire perimeter. This is done in order to create an uneven surface of the glue. This contributes to better bonding of the insulation;
how to insulate a wall in a corner apartment from the inside? Next, we take sheets of heat insulator and begin to install them on the walls. First of all, the bottom row is laid. We tightly apply the polystyrene sheet and push it through, you can not use dowels or other fastening materials. When installing, we use a level and carefully join the edges so that cracks do not form, if necessary, cut the sheets. The next row is set so that the junction of the two sheets falls in the middle of the bottom sheet. This will give great durability to the entire structure.

Watch the surface of the insulation so that unevenness does not form, because this will bring additional difficulties during the final finishing.

after you have installed the thermal insulation, you can proceed to finishing work. If you plan to cover the walls with drywall, then no additional work on the insulation is required. If you plan to cover it with a layer of plaster, putty, wallpaper, painting, then you need to treat it with a primer, then install a mesh of reinforcing fiber. After that, you can start applying layers of plaster or putty.

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

Wall insulation 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, it is necessary to attach the "" sheets to the wall using fasteners.

After that, the sheets are connected to the electrical network of the apartment. In the most severe frost, we turn on the system and warm up the walls until they are completely dry. After that, we lay the thermal insulation to prevent heat loss. Then you can start lining the walls.

So, if you decide to insulate the walls of a corner apartment, you need to choose the material, focusing 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:

installation of insulation reduces the volume of the room;
poor quality 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. Warming the walls of the apartment from the inside is a fairly simple process.

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

In buildings where panel walls are installed, it is often necessary to perform insulation. Just the thickness of such walls is not enough. The following is observed: the room cools down quickly, while the heating system does not cope with the tasks set in all cases. As a result, the temperature in the rooms drops, the residents feel uncomfortable. The problem must be solved. This will be discussed - how to insulate a wall in an apartment from the inside on your own. What materials should be used for this work, how to apply them correctly.

Walls in the apartment and their insulation

External thermal insulation of walls - this method can be called one of the most effective, if you need to keep warm in the apartment.

But this option is expensive - the complexity of implementation is too high, it is necessary to use special equipment, hire professional workers. The higher the number of storeys, the more difficult and costly.

Wall insulation in the apartment from the inside is fully justified in different cases. For example:

If there is a ban from the authorities that the facade of the building cannot be changed. This happens if the building is of cultural value, or if the front of the house has access to the main street;
If behind the wall there is an expansion joint between a pair of buildings;
When the elevator shaft is behind a wall, or there is any other room that is not heated. Accordingly, it is impossible to mount external insulation in such a situation.

There is an exit! The best choice is to insulate the walls from the inside in the apartment. Yes, this will cut off the usable area in the premises a little. But warm rooms of a slightly smaller area are better than spacious cold rooms. Moreover, if you work inside, you can do the work yourself, without hiring specialists. The main thing is to act correctly: prepare the necessary tools and materials for work.

When autonomous heating equipment is installed in an apartment, insulated walls perfectly help save energy resources - this is exactly what any owner wants to achieve.

More about the pros and cons internal insulation if you can't make a decision:

Positive sides:

The cost of work will be affordable for almost any family;
Installation can be done regardless of weather conditions;
In the process, it will be possible to align the walls.

Minuses:

Condensation may appear, and the formation of mold colonies should not be ruled out. To avoid this, you will have to think over high-quality ventilation - then these problems will not exist;
The wall does not accumulate heat, does not retain it. Often the losses are 15%;
If you insulate the wall incorrectly, it will definitely freeze through. After some time, because of this, the material will collapse;
The volume of the room will decrease;
The interior decoration of the rooms will suffer;
Residents often experience inconvenience if the apartment is being renovated.

Insulation from the inside - how to do it right

It is worth noting that the thermal insulation of the walls of the apartment from the inside, which in the future will prevent the appearance of condensate due to temperature fluctuations in the winter, as well as the occurrence of mold spots on the walls, must be carried out correctly - all technological recommendations must be followed.

When a thermal insulation "pie" is formed, its structure is created, and high-quality vapor barrier is necessarily made. It should protect the insulation from moisture ingress into it.

Before proceeding with the insulation of the wall in the apartment inside, it is worth studying a number of recommendations on how the work is done:

It is necessary to buy a high quality vapor barrier film - this is a must. Also, the shopping list should have waterproof tape so that you can seal all the joints between the sheets without any problems;
A material with low vapor permeability is being prepared - this indicator should be lower than that of the walls. This approach is a guarantee that moisture will evaporate correctly towards the street, there will be no evaporation into the apartment;
It is important to glue the insulation as tightly as possible to the wall surface - this will be confirmed by any experienced craftsman;
Inside the room it is necessary to equip ventilation - it can be either forced or natural. Due to this, there will be no excess moisture. For example, special valves are often placed on window frames today - it is through them that fresh air will enter the room, which is very convenient;
Before insulating the walls in the apartment from the inside, it is necessary to correctly calculate the thickness of the insulation, which will be optimal.

This value depends entirely on what your region is the average daily temperature in winter. What happens if the thermal insulation material turns out to be less than the design parameters? There will be a violation of the steam-thermal balance.

The wall insulation system is installed after special primer solutions have been applied to the surface. This will help protect against mold, and adhesion will also be increased, which is important if thermal insulation is being arranged;
Installation of insulation should be carried out strictly on the wall, which is thoroughly dried;
When a heater is installed, "cold bridges" are considered unacceptable. Especially where there are butt seams. It is these "bridges" that can spoil the whole process, significantly complicate the work.

What materials to use for insulation

Each owner decides how to insulate the walls in the apartment from the inside.

We only need pay attention to a number of materials and their features to make the right decision.

Penofol - in detail

Material advantages:

Is environmentally friendly;
Compared to other materials, it has a small thickness;
The level of vapor permeability is low;
Noise isolation is high;
Installation is easy;
The level of fire safety is high;
Transportation is made without any difficulties;
The material is not liked by rodents.

Minuses:

This material is soft, so light pressure is enough - dents are instantly formed;
To perform high-quality fixation, a special glue is used;
If the wall insulation is external, foil foam is used as an additional heat-insulating layer. It is due to it that thermal energy is reflected, reliable protection against moisture is created - you need to know about this.

mineral wool

Positive sides:

The material is not combustible;
Has low thermal conductivity;
Sound isolation is high;
There is good breathability and vapor permeability;
For rodents, mineral wool is of no interest; the same can be said about insects. Constructions are even a fact.

Negative sides:

Absorbs moisture strongly;
Do not do without additional vapor barrier;
If mineral wool is used for a long time, shrinkage may occur;
The area of the rooms will decrease, as the material has a greater thickness.

Ecowool as a heater

Advantages:

The material does not burn;
Is environmentally friendly;
Has low thermal conductivity;
The level of sound insulation is high;
It can be in operation for a very long time.

Minuses:

It costs too much.

Expanded polystyrene for insulation of the apartment from the inside

Positive sides:

Plates do not weigh much;
Strength characteristics are high;
The price is much lower when compared with mineral plates;
Easy to process;
It is not hygroscopic.

Negative sides:

Soundproofing leaves much to be desired;
Vapor permeability coefficient is low;
Partial destruction cannot be ruled out if the temperature rises above 80 degrees;
Low resistance to various organic solvents is observed;
Limited in use. If the height of the house is more than 25 meters, it is not recommended to use it;
The plates are combustible. Expanded polystyrene is a self-extinguishing material, it does not support combustion.

An interesting point: if it turns out that the expanded polystyrene plates do not fade themselves, this indicates one thing - the material does not meet the requirements of the standard. It is forbidden to use it in the apartment.

polyurethane foam

Advantages:

The insulation is made right where the work is being done, which is very convenient. The set of required components is minimal. Accordingly, shipping costs are reduced;
Weighs little;
In addition to insulation, it gives the wall additional strength;
Able to withstand a wide range of temperatures - from minus two hundred degrees to plus two hundred;
When the installation is completed, the owner will see a solid canvas, there will be no seams here.

disadvantages:

If the polyurethane foam gets sunlight(direct UV rays), wear occurs quickly;
It is necessary to protect the additional insulation received. Plaster, any panels will help with this. Some use plain paint. However, this is even good - the surface eventually becomes as aesthetic as possible. When - the same thing is done;
When the temperature is high, the insulation can smolder. If there is strong heating, a fire cannot be ruled out, this also happened.

Cork as a heater

pros:

Weighs very little;
The material is strong, hard;
It is not subject to rotting, mold does not appear due to exposure to moisture;
Cork is an absolute dielectric, static electricity does not accumulate;
Is not combustible. If smoldering - toxic, harmful substances not highlighted;
Rodents are not afraid;
When the humidity level fluctuates, the cork does not change volume, unlike many other heaters;
Installation work is carried out easily, so even beginners will not have problems with how to insulate the wall in the apartment from the inside;
Complete environmental safety.

Minuses:

It is expensive, not every family can afford it.

Plaster

Advantages:

Very easy to apply;
Remarkable adhesion is observed with any kind of surface;
In difficult preparatory work there is no need. Plaster is a plastic material, so it will level the wall itself;
Application is easily done manually, but if you want, there is always an option to use auxiliary technical devices;
Irregularities can be eliminated without problems - defects, cracks, all this is not a reason for unrest;
There are no cold bridges.

disadvantages:

When the application of the plaster is completed, it is necessary to do an additional primer, staining;
If you plan to apply “warm plaster” - the wall must be dried before work;
Since the coefficient of thermal conductivity of the plaster is large, high-quality insulation can be obtained only when the mortar layer is thick - this is not always convenient.

Above, we examined the main materials that are suitable for insulating walls from the inside in an apartment. There are actually a lot of options here..

When walls are insulated in an apartment, two basic rules must be remembered: organize a strong vapor barrier so that condensate does not appear between the insulation and the wall. Also, over to make good ventilation - all moist air from the room should be removed.

Before insulating the walls in the apartment from the inside, in order to protect yourself from unnecessary expenses, it is better to carefully study this topic. All thermal insulation materials that exist today are usually divided into groups, which, in turn, correspond to the material that was used in the construction of the walls of the house - it is important to remember this so that the end result is positive.

Let's look at a few examples:

If the wall is made of brick, you do not need to choose the insulation that is designed for concrete walls. IN this case expanded polystyrene foam is perfect;
When concrete walls are insulated, polystyrene foam is also often used. The main thing is to choose an extruded material;
For concrete walls, any insulation will do. But here it is also necessary to use a vapor barrier material on any of its surfaces. The ideal solution is foil, this material will provide the necessary protection.

Warming - features of work inside the apartment

It is worth talking in detail about how to interact with one or another heater so that the apartment is warm and the positive effect is preserved for years.

How to insulate with penofol

To achieve the best result, it is necessary to make an air gap on both sides.

Acceptable indicators - 20 mm. In this case, penofol is fixed on a wooden crate, which, in turn, is attached to the base - this is how the desired strength is achieved.

What is being done for this:

Detailed description:

Wooden planks, two centimeters thick, are attached to the wall surface. This is done vertically, it can also be done horizontally. The step is chosen depending on the width of the roll;
Planks in wooden walls are attached with self-tapping screws, and dowels are used for brick and concrete surfaces;
They take rolled material, strips of the desired length are cut from it. Then they are shot with staples to the planks - a construction stapler will help in this;
Penofol webs are mounted end-to-end, the material is installed inside the room with the foil side;
Each joint must be carefully glued with aluminum tape;
The planks are installed and attached to the crate - it is they who will provide the air outer layer of the desired size;
The walls are sheathed on the outside with sheets of drywall, lining or other materials are also used for this.

Mineral wool insulation - details

Working with this material is somewhat more difficult - you can not do without wooden slats. And the installation order looks something like this:

Vertical slats are placed on the walls - this is done using the building level. Just one plane should be provided for all elements;
The waterproofing layer is placed between the rails, you can also fix directly to the rail;
How to insulate a wall in an apartment from the inside now? Very simple - it remains to lay only the insulation itself.

So that there are no cold bridges, the heat-insulating material is placed extremely tightly in the cavity between the slats. In size, it sometimes has to be cut - but only a little more than the distance between the slats. The fact is that there should not be any gaps between the canvases, even minimal ones.

After they put a vapor barrier material, they perform fasteners with slats;
If there is no plaster layer, the ideal approach to business is to lay mineral wool in two layers, this will be more than enough.

About insulation with polystyrene foam

This solution can be called one of the cheapest and easiest if you need to insulate an apartment. If the walls are built of brick, the first thing they advise is to plaster, only then move on.

What then? Following:

When the coating dries, the wall is leveled - putty is used for this;
Put waterproofing material, which will one hundred percent protect the wall from the appearance of condensate between the insulation and the main one;
Next, you can install sheets of insulation. For fastening, a special glue is usually chosen. At the same time, the composition is not applied to the foam, but directly to the surface of the wall - this is correct;
It is recommended to place foam panels end-to-end, there is no need to make any gaps here;
They put a vapor barrier material, you can’t do without it.

How to insulate with polyurethane foam

To spray polyurethane foam, you need to use special equipment- no other way.

Besides:

A wooden crate must be mounted on the wall - it is she who will act as guides when the material is sprayed. It will also be the main one, on which the decorative trim will be fixed;
Then the polyurethane foam is installed;
Attach trim panels. In general, nothing complicated.

Plaster and work with it

What should be done before insulating the walls from the inside in the apartment with plaster? It is important to study some features of the forthcoming work. For example, warm plaster is applied to the walls in three layers - this is important.

The first step is spraying with liquid plaster - so that the composition can get into all the cracks. The composition is thrown evenly, with a certain effort. The layer thickness should be at least 1 cm;
Now apply soil. If they are thermally insulated with plaster, it will be the main one. A coating thickness of 0.5-0.6 cm is sufficient.

It is best to apply the primer in several layers, while the size of each can be 2-3 cm. Due to this, the coating will not separate from the walls due to its weight. After application, it is important to dry each layer thoroughly.

Now the cover. That is, the finishing layer, which has a thickness of up to 0.5 cm. To make this layer, fine clean sand is used, which is diluted with water. This composition is easily rubbed into the wall surface, a completely flat plane is obtained.

Cork and insulation

What to do if you need to insulate the wall in the apartment with a cork from the inside. In fact, there is nothing complicated here - first the surface is prepared: ideally, the base should turn out to be as even as possible. This process is controlled by the building level.

How to get the desired result? So:

If the surface of the wall is not smooth enough, it must be plastered, then various cracks, protrusions, depressions, and other flaws are removed;
When the leveling work is done, the room must be left to dry thoroughly.

It is not necessary to carry out wall insulation with cork materials inside the room if the surface is damp. Because of this, not only fungus can occur, but the panels can also be deformed.

When installing the insulation, it is necessary to strictly follow the instructions for the adhesive - this is very important;
During operation, the strength of the coating will be worthy only when all the technological aspects of the work are performed correctly;
The cork, on which the glue was applied, is simply applied to the wall. Then the material is strengthened. At the same time, it is important to act accurately and accurately. Many cork adhesive bases set very quickly, almost instantly. That is, it will no longer be possible to somehow change the location of the product after laying on the wall.

The video “how to insulate walls in an apartment from the inside” will tell you in detail about the process of insulating a wall inside an apartment - the lesson will be useful to everyone: how experienced master as well as a newbie.

During the installation of the cork, it is important to ensure that the room is well ventilated. Glue can easily be toxic, in addition, the compositions usually have bad smell(very sharp).

All the recommendations discussed above will help to reliably insulate the walls in the apartment from the inside. How to do this in the end is up to the owner to decide, only he knows the answer to the question of what heaters will be used. Cold should not get into the apartment. If this is observed, the problem must be solved as soon as possible, then life in the room will be comfortable.
