The best ways to insulate the walls of the house from the inside. How to insulate a house without touching the facade - an elementary guide to internal insulation How to insulate the walls of a house

How to competently solve the issue of insulation of a building, house or cottage after the completion of the main construction work? Any experienced builder will unequivocally answer: not only external insulation is necessary, especially if the building is made of brick and other materials that conduct heat well.

Causes of moisture

In the winter season, with the onset of frost, the walls of our houses freeze through. In a correctly calculated wall thickness, the transition point from minus to plus temperature, it is called the dew point, is located inside the wall and condensation does not occur. That is why they used to build houses with stone walls no less than 80 cm thick. Today, with the use of the latest construction technologies and innovative materials, it has become possible to build houses with thinner walls, but such buildings require the installation of additional heat-insulating structures.

The question arises: from the outside or the inside to carry out insulation?

The issue of exterior finishes disappears when the house is made of timber and does not require exterior finishing. If the house is made of stone, then it will be more competent to make insulation from the facade, but this does not exclude the carrying out of internal work.

There is the only exception - the internal insulation of the walls of an apartment in a multi-storey residential building, where the use of any type of heat-insulating material will not give tangible results.

How to insulate your home

If it is decided to abandon the facade insulation, then how to insulate the house from the inside to avoid condensation? After all, it is he who leads to the appearance of fungal formations, the destruction of thermal insulation materials. Each owner needs the entire thermal insulation internal structure to work efficiently and functionally. There are several widely used home insulation technologies.

Insulation of a log or timber house has its own characteristics. The thermal conductivity of wood in comparison with stone is, of course, lower, and wood retains heat well, however, when walls are insulated from the inside, moisture can form between the inner surface of the wall and the surface of the insulation. To avoid this, an air gap is made to blow wood and insulation. Technically, the problem is solved using a frame crate made of wood with a frame width equal to the width of the insulation boards. The crate is mounted at a distance of several centimeters from the wall to provide a ventilation effect.

From the side of the wall, a windproof membrane is pulled onto the frame, which performs a dual function: it protects the air gap from overlapping with the fibers of the heat insulator and limits excess air movement inside the insulation. In this case, it is more expedient to insulate the walls from the inside with natural environmentally friendly materials. There is a wide selection of mineral wool insulation, in Russia the most famous manufacturers are: URSA, ISOVER, ROCKWOOL, KNAUF and others. From the side of the room, the insulation is hermetically covered with a material that provides protection against the penetration of steam into the inner layers of the heat insulator.

The technology for insulating concrete or stone walls is similar to the previous design, but in this case it is necessary to provide for a larger number of technological openings for air to enter. Much more condensate will appear than in the first case, and the air gap must be wide enough for intensive ventilation. In fact, it is necessary to build an additional internal wall.

When carrying out thermal insulation work indoors, it must be understood that natural physical processes will affect the entire structure. This work requires a competent professional solution.

As a result, several main conclusions can be drawn:

When installing thermal insulation on the inside of the walls of the house, the dew point inevitably moves to the inner surface of the wall. This will happen even with correct calculations of the thickness of the heat insulator. As a result, the service life of the entire thermal insulation structure is reduced.
The thermal insulation structure must necessarily include a vapor barrier membrane. As a result, it is necessary to solve the issue of normalizing the humidity in the room (increase in the cost of heating and ventilation systems).
Insulation inside the room reduces the volume of rooms.
Since the entire structure is installed inside the house, the issue of human safety becomes the most important. It is important to understand which of the heaters best meets this requirement. Materials from natural raw materials are the best choice. Soft slabs or mineral wool rolls, which have high heat-shielding and sound-proofing properties, are well suited. All materials with good vapor permeability and ability to absorb moisture will lose their functional properties over time.
The use of expanded polystyrene or polystyrene, as materials that practically do not absorb moisture, is more beneficial. In this case, it is necessary to consider the hermetic fit of the plates to each other. The main disadvantage of this option is a completely synthetic material, and they will have to breathe.
Today there is a lot of talk about polyurethane foam, which hardens when applied to the surface, and, of course, gives a strong adhesion to the inner surface of the wall. Condensation does not form, but for the work it is necessary to construct technological formwork. This process is quite long, while the wall does not breathe.

There are many wall heaters, there are plenty to choose from, but the decision must be made correctly. People will live, work and breathe in this house.

Video tutorial on interior insulation

You can insulate the house from the inside yourself. To do this, it is better to familiarize yourself with the video material:

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.

The walls can freeze completely, especially in the corners, the interior decoration will begin to fall off, mold and 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 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 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, condensate can accumulate on wooden walls, 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 is an excellent material for insulating the walls of the apartment. 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

This is relatively new material. It is sold in containers of various sizes, as it is a 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 applying the 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 a panel house from the inside.

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 the 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? You can insulate a corner apartment in a panel or monolithic house 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 a brick house can be insulated using the same method as in a panel house. 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 the 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.

When living conditions in a country house cease to be comfortable, urgent action must be taken. This concerns primarily lowering the air temperature inside. If the building freezes, it will be necessary to carry out thermal insulation work.

Wall insulation from the inside is not very welcomed by modern professionals, but sometimes it is impossible to do this from the outside. In order to be satisfied with their own work and not doubt the durability of the thermal insulation of the house, novice builders need to buy high-quality material, prepare the building wisely, and also comply with a number of requirements during the installation process.

The need for insulation of the inner surface

If the design of a country house allows you to carry out thermal insulation work outside and inside, it is better to implement both methods. Alas, some circumstances force residents of private buildings to neglect external insulation. These include:

location immediately behind the wall of another building or other object, the distance to which will not allow placing a layer of heat insulator;
passing on or inside walls of energy cables and similar equipment that cannot be removed;
the presence of an expansion joint between buildings behind the wall;
the prohibition of the authorities to modify the facade (for example, an object of cultural heritage);
acute reluctance of residents to change the appearance of the building.

If at least one of the conditions above takes place, you can limit yourself to insulating the walls inside.

Regulatory requirements for microclimate parameters

There is no consensus among people about what is considered comfortable conditions. However, referring to GOST 20494-96 (“Residential and public buildings. Indoor microclimate parameters”), residents will find the following prescribed characteristics:

air temperature inside the house - from 20 to 22, floor - from 22 to 24, walls - from 16 to 18 degrees;
the room should accumulate and save heat;
air humidity varies from 50 to 60%;
complete absence of drafts (wind speed in rooms is up to 0.2 m / s).

The presence of deviations from the parameters prescribed by GOST is a sufficient reason for carrying out insulation work from the inside.

Features of sheathing the inner surface of the house

The impossibility of external thermal insulation of the walls is in itself a disadvantage of the structure. To it you can add the following minuses of the skin inside:

reduction of the useful area of the room (in the case of floor and ceiling insulation - also volume);
although the temperature gets higher, there is no accumulation of heat in the walls - they remain cold;
the previous fact contributes to the formation of condensate, which causes dampness, mold, corrosion, and the appearance of microorganisms.

Fortunately, there are also advantages, and the main one is the normalization of the microclimate of the premises.

Distinctive features of the internal thermal insulation of the walls of a private house, regardless of the material of the latter, are:

The presence of two additional layers - hydro and vapor barrier. The first reduces the likelihood of moisture getting on the insulation from the outside, the second - from the inside (from the side of the rooms).
Rapid temperature change in the room when opening vents, windows, doors.
When using some heaters, “cold bridges” may appear - sections of the walls where condensate with cold air is concentrated.
If possible, it is worth using environmentally friendly material for sheathing from the inside.
You can save on wall insulation, which cannot be said about outdoor work.
Performing work inside the house in comfortable conditions all year round - the process will not be affected by natural factors.
The presence of assistants is not necessary - all steps can be easily completed on your own.

Important requirements are imposed on the design at the preparatory stage of the lining inside. The key one is the maximum dryness of the walls.

Preferred materials for internal thermal insulation

The range of heaters presented in hardware stores is large. The following are quality materials that are best suited for interior cladding of houses.

The material is relatively cheap, has good thermal insulation characteristics. Suitable for all types of houses, except brick. The coefficient of thermal conductivity is not the highest - there are analogues with better performance. Other advantages of using polystyrene foam are:

durability (30-50 years depending on the region where the house is located);
lightness of the material (supplied in slabs that weigh a couple of hundred grams);
ease of installation.

The cons are:

susceptibility to fire;
you can break or crumble the material if mishandled;
poor vapor permeability;
attraction for rodents;
synthetic materials are used in the production.

A good alternative to the above insulation, which is extruded polystyrene foam. It is denser than polystyrene, it is allowed to insulate any surfaces of the house, but it is expensive. It is better for them to sheathe small areas from the inside of buildings - attic floors, caissons, basements.

low coefficient of thermal conductivity;
minimal tendency to ignite;
poorly absorbs water;
high strength.

high cost;
poor vapor permeability.

Mineral wool

A modern material that is gaining popularity within the Russian market. Supplied in plates or rolls of various densities and thicknesses (from 2 to 10 cm). In terms of environmental friendliness, it is better than the two previously described heaters, suitable for any home, has a low coefficient of thermal conductivity (approximately equal to foam).

low flammability;
resistance to rodents, insects;
excellent vapor and air permeability;
additionally acts as a good sound insulator.

absorbs moisture (if more than 2% of the surface of the plate is wet, you can safely replace the insulation);
a vapor barrier is required (when lining the PPS from the inside, it is permissible to neglect the rule);
the material shrinks, requiring replacement after 10-15 years;
for installation, you will need to make a crate, which will steal a large internal volume of the house.

Ecowool

The most preferred material in terms of environmental safety. It consists of elastic granules that do not allow the insulation to shrink, which distinguishes it from mineral wool.

does not ignite;
durable (up to 50 years);
ecological cleanliness;
soundproofing is akin to mineral wool;
low thermal conductivity.

high price.

Ecowool (recommended first).
Mineral wool.
Styrofoam (extruded polystyrene foam).

Proponents of diversity and unusual solutions can look for insulation from the inside of the options listed below:

Eco-friendly, safe; at the same time they can be used as a heater and decorative trim. Alas, due to the thin layer they are ineffective, they are only suitable for the southern regions.

Styrofoam wallpaper.

They have a thickness of 3 to 10 mm (more than that of cork), can cover wall defects, almost do not reduce the area of \u200b\u200bthe premises, are applied like ordinary wallpaper, only with special glue. They do not smell, they are safe, they protect well from noise, they are moisture resistant - they protect walls from mold. The only downside is flammability.

Isoplat.

An innovative material consisting of two layers - fiberboard with a thickness of 10 to 25 mm and pressed linen. It is mechanically strong, environmentally friendly, but the thermal conductivity is worse than that of the recommended heaters.

The material is obtained by drying wood chips, later mixed with a binder and pressed. The protective layer better warns against rodents, insects, as well as mold or fungus. But it is not suitable for insulation from the inside of most private houses, since it begins to deteriorate at a humidity of more than 35%.

To achieve the normalization of the microclimate in the house due to the insulation of the walls, it is better to tip the scales in favor of proven materials - mineral wool, ecowool, polystyrene. You should not think that the impossibility of external thermal insulation will reduce the heat in the premises, because a competent choice of material and adherence to installation technology will certainly lead to the desired result.

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 efficient way 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 autonomous heating equipment is installed in the apartment, 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, as a result, mold spots do not appear on the walls, all technological recommendations for insulating concrete walls from the inside of the apartment must be carefully followed.

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?

It is necessary to purchase a high quality vapor barrier film and waterproof tape to seal 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, valves are installed on the window frames, 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 is an 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 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 \u200b\u200bthe room smaller - this quality compares favorably with other thermal insulation materials.

Penofol

Penofol, in essence, is a rolled polyethylene foam 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 laying on walls, floors or ceilings, as well as with a long service life.

Prices for thermal insulation materials

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 technological process can be carried out independently.

One of the most important conditions for living in an apartment is good heat supply, for which either a centralized heating system or autonomous equipment installed by residents is responsible. However, the heating efficiency directly depends on the correct thermal insulation of the premises.

Consider how to insulate a wall in an apartment in order to increase the air temperature and at the same time reduce energy costs for heating. To do this, we give two detailed instructions for thermal insulation with popular types of heaters, in which each step is illustrated with photographs.

Also in this material we will consider less popular methods that can be used to insulate walls from the inside.

The preferred way to insulate the walls of apartments and houses is, however, that does not affect the dew point shift and heats the entire wall.

If the insulation layer is mounted on the inside, the wall freezes through its entire thickness, and moves closer to the living space.

A negative consequence of internal insulation is condensation, which eventually destroys insulating and decorative materials, sharply reduces the effectiveness of thermal insulation and provokes the appearance of mold.

However, the external method is not always suitable. Difficulties arise with the installation of insulation on panel skyscrapers, as well as on walls adjacent to technical spaces, for example, an elevator shaft. If the building is a historical object, the appearance of the facade cannot be changed.

However, in some cases, thermal insulation simply cannot be dispensed with:

Image Gallery

If it is planned to build a partition in an insulated room, then it can also be done using mineral wool, but it is better to replace OSB boards with drywall sheets.

Isover is placed between two walls of LGK, with each wall made of 2 layers of drywall. Such a partition will protect from cold and noise no worse than a full-fledged reinforced concrete wall.

Both presented methods have disadvantages that must be taken into account when planning work.

Firstly, they take away part of the usable area and reduce the living space around the perimeter, secondly, they require significant investments from the family budget, and thirdly, when applying them, all the nuances of technology must be observed.

Brief overview of other methods

Other technologies are also used, among which there are both outdated, but cheaper, and modern, requiring considerable investments.

Installation of expanded polystyrene or polystyrene

With the advent of EPPS, it has become impractical to use ordinary non-pressed polystyrene foam (PSB), since it has degraded characteristics.

Namely:

burns and melts releasing hazardous substances;
is fragile, due to which the pieces break under mechanical pressure;
not protected from rodents.

In terms of parameters, it is inferior to extruded polystyrene foam, and this can be seen from the table of physical and technical properties of expanded polystyrene plates.
