Additional insulation of indirect corners in a new building for. Some methods and recommendations for warming a corner apartment

Insulation of an apartment is a troublesome, but very useful procedure that allows you to improve the microclimate in your home, create comfort and coziness. The need for this event arises if the heating networks do not cope with their task, or when the configuration of the room contributes to an increase in heat loss. For example, corner apartments that have an additional window, but in return receive a cold corner that is constantly wet or covered with a crust of ice. The recommended SNiP increase in temperature by 2 ° or an increase in the number of sections in heating radiators does not give the desired effect, requiring more effective methods. Let's figure out together how to insulate a wall in a corner apartment from the inside and what needs to be done for this.

What does "corner apartment" mean?

Corner apartments are located in the end sections of residential buildings. One or two rooms in such apartments have two adjacent walls bordering the street. The layout of such apartments is no different from the configuration of all the others in the house, only an additional window and a heating radiator appear, moreover, such an addition is not found in all corner rooms. To compensate for heat losses through enclosing structures resulting from an increase in the area of ​​external walls, an increase in the internal temperature by 2 ° is provided, which is ensured by an increase in the standard number of radiator battery sections. In practice, this is achieved either by having a battery installed under an additional room window, or by installing a larger radiator (number of sections).

These measures rarely work as intended, as they are designed to solve the problems of the conventional premises and do not take into account many of the impacts that exist in reality:

• The outer wall is located on the windward side of the house;
• Depreciation of heating networks, non-compliance of the heating regime with regulatory requirements;
• Mistakes and shortcomings made during the construction of the house.

These factors are often present all together, significantly changing the temperature in the apartment for the worse. The cold surface of the walls begins to get wet due to the active formation of condensate, the apartment becomes cold and uncomfortable. Such situations are quite common and require appropriate measures.

Wall freezing is a common occurrence in corner apartments.

Ways to insulate an apartment

Insulation consists in installing a special material on the outer walls - a heat insulator. There are two types of insulation:

1. External (external). Experts unanimously consider this technique the only true one. The heat insulator is installed on the outside of the walls, which are separated from contact with the outside cold air. As a result, the thermal circuit of the room begins to operate in the nominal mode, the surface temperature of the enclosing structures returns to normal, and the formation of condensate stops.
2. Internal. Forced option, used when it is impossible to produce external insulation. The insulator is installed on the inside of the walls. The volume of the room decreases (slightly), it becomes necessary to install a durable protective layer over the heat insulator. The main disadvantage of the method is the exclusion of walls from the composition of the thermal circuit of the room. From now on, they perform only the functions of an external mechanical barrier, not participating in the heat saving of the apartment.

External insulation has a lot of advantages:

• Works are carried out outside, without creating inconvenience for living.
• The surface of the walls remains intact, the interior of the room does not change, there is no need for sheathing or decoration.
• The microclimate of the room improves, there is a feeling of coziness and comfort.

The disadvantage of external insulation is the complexity of the work outside, the reasons for which may be:

• The apartment is located on one of the upper floors;
• The facade of the building has an architectural value, as a result of which the installation of any materials is excluded;
• Any technical or decorative objects are installed on the wall;
• The building is located close to other buildings or structures;
• Work can only be carried out during the warm season.

Internal insulation is almost completely devoid of these shortcomings, no permit is required for work, you can work at any time of the year. And yet, experts prefer external insulation. The reason for this is the presence of water vapor in the internal air of the apartment. It is gradually absorbed into the outer walls, passes through them and evaporates from the outside. This process happens all the time in any living space. Mounting the insulator from the outside does not stop it, you just need to correctly organize the progress of work. With internal insulation, water vapor is locked inside the apartment, which has a sharp negative effect on the microclimate. There is a strong humidity, a feeling of stuffiness, lack of comfort.

It is important! The solution to the problem is the installation of a high-quality ventilation system that removes internal air saturated with water vapor.

The choice of internal insulation, as a rule, is due to the lack of the ability to work outside. Outdoor work requires a permit, which is not easy to obtain. In addition, to install a heat insulator, you will have to involve industrial climbers, which will be quite expensive.

External thermal insulation is more preferable, but is associated with high costs

Therefore, most apartment owners choose a more affordable and simple option - internal insulation. The method allows you to get a positive result, it is only important to correctly understand the physical essence of the process and organize it in the right way.

Types of heaters

There are many insulation materials on the market. Consider the most popular heaters in detail.

Mineral wool

One of the most successful options is stone (basalt) wool. Usually, when it comes to mineral wool, they mean exactly stone, although the term denotes a wide group of materials, which include slag wool, glass wool and other types of similar insulators. Basalt wool is more convenient to use, has a good set of operational and technical characteristics. It does not burn, does not emit harmful substances and is not subject to decay. It is produced in different forms - from rolled to more rigid slab. The disadvantage of mineral wool is the ability to absorb water, which makes installation somewhat difficult and requires additional operations.

Mineral wool slabs are one of the most popular insulation for walls and other surfaces.

Styrofoam

This insulation is a confident leader among all other types in terms of popularity. The reason for this is the low price of the material, low weight, ease of installation and processing. The material is resistant to water, has stable dimensions and geometry of the plates, impervious to water vapor. For internal insulation, this is the most preferred option, budgetary and not time-consuming.

Styrofoam is suitable for both internal and external insulation

Penoplex

From a chemical point of view, this material is a complete analogue of polystyrene - both of them are variants of expanded polystyrene. But unlike polystyrene, which is expanded polystyrene granules connected during heat treatment, foam polystyrene (extruded polystyrene foam) is a monolithic material, hardened foam. It is stronger and heavier than foam, has a higher price.

Penoplex does not crumble during processing, it is completely resistant to moisture or water vapor.

polyurethane foam

A specific heat insulator, sold in liquid form and applied by spraying onto the surface to be treated. In air, the material foams and hardens, as a result, an airtight layer is formed, resembling mounting foam. Polyurethane foam is ideal for insulating walls with complex geometry, the presence of small defects or protruding parts. The price of the material is quite high, in addition, special equipment is used for application. These factors somewhat limit the use, although the performance of the insulator is very high. It is completely impervious to moisture, sealed and perfectly covers the surface without gaps or gaps.

Wall insulation with sprayed polyurethane foam

There are other materials that can be used for internal insulation. It is not advisable to list them all, since they are noticeably inferior to the named species in terms of operational and technical characteristics or are expensive.

It is important! When choosing a material, it is necessary to take into account an important parameter - vapor permeability. For internal insulation, it is important to qualitatively cut off the wall from any contact with internal air, otherwise it will start to get wet. If a non-vapour-permeable material is used, install it firmly and without gaps on the surface.

Permeable types of heat insulators require the installation of a vapor barrier film, which increases the number of installation operations and requires additional costs. Permeable types of insulation include mineral wool and polystyrene, foam or polyurethane foam are impervious to steam or water.

Carrying out work

The process of insulation consists in installing a dense layer of heat insulator on the entire surface of the outer walls. A feature of the insulation is the need to install a protective and decorative sheathing on top of the insulation, for which it is necessary to create a supporting structure - battens. It is a series of planks forming a vertical plane located at a distance from the wall equal to the thickness of the heat insulator. It is tightly inserted between the planks of the crate, forming a continuous layer without gaps or gaps.

Insulation of corner apartments is characterized by the need to install thermal insulation on two adjacent walls, which increases the consumption of lathing, insulation and vapor barrier. In addition, the overall volume of work is increasing. It will be necessary to qualitatively and hermetically insulate the joint of the two walls.

Procedure:

1. Surface preparation. All foreign objects, hanging lamps, brackets, flower beds, etc. are removed from the wall.
2. The walls are marked, the attachment points of the lathing slats are determined. The markup should take into account the width of the insulation and the battens of the batten, so that you do not have to subsequently adjust the heat insulator.
3. Lathing installation. Wooden bars or metal guides for drywall are used. The installation of metal elements is more convenient, it allows you to get the exact distance from the wall, corresponding to the thickness of the insulation. At the same time, metal parts are able to create the so-called cold bridges, which form pockets of condensation. Wooden planks do not form cold bridges, but require great precision in installation.
4. Installing a vapor barrier. This item is only necessary when using mineral wool. Vapor barrier is an ordinary polyethylene film (you can take a standard sleeve). Installation is carried out in horizontal stripes. The first row is below, the next overlap is at least 10 cm above it - and so on until the wall area is completely covered. The joints of the film must be glued with construction tape. Installation is carried out on top of the lathing laths, the film is wrapped around them and fits snugly against the wall.
5. Installing a heat insulator. Slabs (or cut pieces) of material are tightly inserted between the battens of the crate. You need to keep a bottle of mounting foam on hand to immediately fill the cracks or gaps if they appear. Some experts recommend covering all edges of the insulation with mounting foam in order to seal even the smallest gaps.
6. A second layer of waterproofing is installed on top of the heat insulator. For impermeable materials, a polyethylene film is suitable, but for mineral wool it is better to take a vapor-waterproofing membrane. It has the ability to pass water vapor in one direction. When installing, you must carefully monitor that the material allows you to remove steam from the inside of the formed cocoon. This will ensure that the heat insulator dries out if water gets into it in any way.
7. After that, a layer of protection is attached to the surface of the lathing slats. Actually, the crate is installed precisely in order to have a supporting structure for mounting the skin. Usually sheet materials are used - plywood, drywall or the like. Some owners prefer lining or wall panels. The choice is determined by the capabilities and preferences of the owner.

Stage of installation of waterproofing for internal wall insulation

One of the options for installing a protective layer is the application of plaster. The works are associated with the use of wet solutions and require some time to dry, but the result is quite decent, masking the work done in the best way. If you plan to use plaster, you can do without crates. The insulation is tightly installed on the wall using an adhesive composition, after which a fiberglass reinforcing mesh is attached to the surface and a layer of plaster is applied. This option is best used if foam is used as a heater. The ability to refuse to install the crate allows you to use a fairly thin insulation, while maintaining the volume of the room. Simplified work in the area of ​​​​radiators and risers of the heating system, it becomes easier to insulate the window opening.

The use of warm plaster is one of the most effective ways to reduce heat loss.

After the installation of the skin, the finishing is done. All works are carried out indoors, so they do not depend on the season or the weather outside. No permits for internal insulation are needed, these actions do not constitute a redevelopment or even a reorganization of residential premises.

Insulation of a room in a panel house

In panel houses, the main problem areas are interpanel joints. Insulation will not be effective enough if the joint is not previously sealed, for which it is necessary to open it as much as possible along the entire length of the wall. Usually, the joints of the plates are sealed with tow, gypsum or plaster. The gap should be opened as much as possible with a spatula or a narrow chisel. Remove old tow, aggregate or other material. Then you need to examine the resulting gap and determine its depth. The best option would be to fill the joint with mounting foam. It is not difficult, it is carried out quickly enough and allows you to effectively seal the joint.

It is important! After the foam has hardened, the parts protruding from the gap are carefully cut with a knife to form an even angle. Further work is carried out according to the general technology of insulation.

Insulation of a room in a brick house

Brickwork is well tied up at the corner joints and does not have slots with access to the outside. This allows you to work without preliminary insulation of the connection of the planes. At the same time, the properties of the material require hydrophobization before installing the heat insulator. To do this, the brick wall to be insulated is cleared of the plaster layer over the entire area. After that, the surface is covered with a layer of water repellent with a brush or roller. It is necessary to use deep penetration material for interior work. Some types require application in several layers, as written in the instructions on the package. After the composition has dried, a heat insulator is installed on the surface of the walls using conventional technology.

Insulation of corner apartments is a forced measure, dictated by mistakes made during the construction or design of housing. The main task of the owner is a dense and hermetic installation of a heat insulator that completely cuts off external walls from contact with the internal atmosphere of the apartment. Any gap forms a section that will constantly get wet and gradually impregnate the entire area of ​​\u200b\u200bthe wall, which will sooner or later lead to its destruction. Accuracy and thoroughness in the performance of work will allow you to get a high-quality and effective result that changes the thermal regime in the room and increases comfort for residents.

The corner apartment has some special features. A clear disadvantage is that its two walls border the street, which increases heat loss. In addition, the corner freezes, which leads to the formation on the surface, as well as a violation of the integrity of the decorative coating.

To avoid this phenomenon, you need to know how to insulate a wall in a corner apartment from the inside. You should start by choosing a heater.

Types of thermal insulation

Today, the market offers a wide range of thermal insulation materials that are used to insulate houses. In order to carry out high-quality thermal insulation, it is necessary to approach the choice correctly.

How to insulate the wall in the apartment from the inside, you will need:

1. Mineral wool. Presented on the market in the form of mats and rolls. Depending on the raw materials used in the production, it is divided into several types: glass wool, basalt and ecowool. Each type has certain advantages and disadvantages.
2. Styrofoam. It is rightfully the cheapest and most popular, which has good thermal insulation properties. It has disadvantages - it does not tolerate exposure to direct sunlight and is very fond of rodents. Styrofoam insulation lasts from 10 to 15 years. From rodents carry out protection from a grid.
3. Extruded polystyrene foam. It has a long service life and is uninteresting to rodents.
4. - very durable, which makes it possible to mount it with self-tapping screws. Its only downside is that it is quite expensive.
5. Polyurethane foam and penoizol. Liquid insulation has the same properties as polystyrene foam.

Polyurethane foam is applied to structures by spraying. As for penoizol, it is used mainly to fill voids in structures. The disadvantage of using liquid polymers is that the technique is quite expensive.

Important! Basalt wool does not burn and is able to withstand high temperatures. It is easy to mount on the wall without special tools and skills.

As for, it has a low thermal conductivity, a high level of environmental friendliness and is not interesting for rodents. Glass wool, in turn, has low technical characteristics, but is affordable.

When choosing heaters, it is worth considering all their technical characteristics. This is especially true for indicators of density, thermal conductivity and vapor permeability. It is also worth remembering that liquid insulation has some application features.

The choice of building materials

1. Mineral wool. In this case, it is recommended to use basalt products. This is due to the fact that basalt wool has high thermal insulation properties and is easy to install.
2. Extruded and ordinary expanded polystyrene. Very popular among consumers, used for thermal insulation of walls from the inside. The plates have special grooves, which makes it possible to make their joints hermetic. As a result, the risk of cold bridges is minimal.
3. Polyurethane foam. Allows you to quickly carry out the insulation of structures. Liquid insulation has high technical characteristics. It is made into a seamless finish.

The disadvantage of polyurethane foam is that it requires special equipment to apply it. All work is carried out in a special protective suit using gloves, goggles and a respirator.

When deciding how to insulate a room in a corner apartment, it is necessary to perform vapor barrier, which will protect the heat-insulating layer from moisture and thereby extend its service life.

Warm plaster, cork wallpaper, thermal paint and polyethylene foam are sometimes used to insulate walls from the inside.

All of them are somewhat inferior in technical characteristics to traditional options, but still they are used for interior decoration. It is worth considering that some building materials are quite expensive.

Panel and monolithic houses

Wall insulation in a monolithic and in a panel house from the inside with tiled material is carried out in the following sequence:

How to insulate an apartment in a panel house using frame technology. In this case, a frame made of a metal profile or wooden slats is mounted on the walls. After laying the insulation, the frame is sheathed with plasterboard. Any topcoat can be used over it.

Important! The frame method in panel and monolithic houses is used extremely rarely. This is due to the complexity of mounting the frame.

brick buildings

Foam plastic, mineral wool or foam plastic are widely used for wall decoration in a brick house. It can be both plates and rolled products. Often, the installation of insulation is carried out using frame technology.

The main steps on how to insulate a corner room in a brick house:

1. Frame installation. At the initial stage, the installation of the frame system is carried out. To do this, use wooden slats or a metal profile.
2. First of all, two guides are installed along the ceiling and floor. Between them, vertical frame elements are installed. The distance between them should correspond to the width of the plates or roll.
3. Particular attention should be paid to the depth of the frame. It should be equal to the thickness of the insulation.
4. Warming from the inside. After the frame is built, insulation is laid in the voids. If we are talking about mineral wool, then it is necessary to cut a piece with a length equal to the height of the room. After that, laying between the vertical guides is carried out.
5. With tiled materials, things are easier. The required number of plates is laid in the voids. At the end, he cuts the material to fill the remaining space. If gaps are formed, they are filled with mounting foam.
6. Vapor barrier. A vapor barrier film is applied over the insulation. This will protect it from fumes. This is especially important in the case of mineral wool.
7. Frame sheathing. After the insulation and vapor barrier are installed, drywall is mounted. OSB boards are also used for sheathing the frame.
8. A reinforcing mesh is applied to the drywall joints and puttied. After that, the entire surface is leveled by applying putty.
9. Finishing. At the final stage, decorative finishing is performed. Often wallpaper is used for this.

If you do not install a vapor barrier, this will lead to the accumulation of condensate, which will significantly reduce the operational properties of the material and shorten its service life.

The vapor barrier film is overlapped. All joints are carefully sealed with tape.

Before insulating a room in a corner apartment, you need to make sure that there are no cracks or gaps in the wall. If necessary, problem areas are sealed with mounting foam.

Method "electric floor"

With the help of electric heating of the walls, you can create comfortable living conditions in the house. For this, heating cables and mats are used. The first option is less expensive. The system consists of a single-core or two-core heating cable, mounting tape and a temperature controller. Thermal insulation is mounted by different methods.

Important! Before insulating the end wall in the apartment with a cable, polyethylene foam is applied to it. It is not recommended to use materials that conduct current.

Installation of cables according to the "warm floor" system is carried out in pre-prepared strobes or directly on the structure. In the latter case, the heating elements are fixed with mounting tape after application. They are connected to a thermostat. The system starts one month after the plaster is applied.

End walls

To resolve the issue of how to insulate the end wall in an apartment, mineral wool or polystyrene is often used. In such cases, installation work is carried out using different technologies.

The foam is mounted directly on the wall. Before performing work, the surface is cleaned of the old finish. After that, it is leveled and slabs are applied. For fixing, glue and a dowel-fungus are used.

Insulation from the inside based on mineral wool is carried out according to frame technology.

Sequence of work:

1. With the help of a metal profile and rails, a system is made with voids in which the insulation is placed. The distance between the vertical slats must correspond to the width of the roll.
2. When the frame is mounted, cotton wool is laid. A vapor barrier film is laid on top, which will protect the material from the accumulation of condensate.
3. The frame is sheathed with plasterboard. The surface is puttied, finishing is carried out.

Insulation of the end wall can be carried out in any way possible. The main thing is to follow the step-by-step instructions for performing the work.

Panel house

Warming panel house from the inside and outside has some features. First of all, it concerns the high-quality preparation of the structure for cladding.

Installation of thermal insulation takes place in several stages:

1. Training. Before carrying out thermal insulation, the structure is carefully prepared. The surface is cleaned and treated with a soil solution. If there are gaps and other defects, then they are eliminated with putty or mounting foam.
2. Insulation of a panel house from the inside. Often foam is used for this. To do this is quite simple. You just need to apply the adhesive on the wall and attach the material. To ensure reliable fixation of the plates, experts recommend additionally using special dowels.
3. Putty and finishing. When the heat-insulating layer is mounted, the wall is completely puttied using a special mesh, on top of which a leveling layer is applied. At the final stage, the finishing of the structure is carried out.

When sheathing panel houses, special attention should be paid to the condition of the surface. This is especially true for the seams between the panels. Otherwise, foam insulation will not give a high effect.

Finishing the corners in the apartment

To insulate a corner room in a brick or panel house, a number of measures must be taken. With certain skills and knowledge, all work can be done by hand.

Thermal insulation of the apartment is carried out in the following sequence:

1. Insulation of windows and balconies. In this case, we are talking about glazing. To protect the room from heat loss, it is necessary to exclude the main sources of cold and drafts. The best solution would be the installation of plastic windows. In this case, the design must have at least two chambers.
2. Front door insulation. It is also a frequent cause of large amounts of heat loss. If the apartment has an old door, then it is better to replace it with a modern model that has high heat and sound insulation properties. Particular attention should be paid to the gaps around the door frame, there should not be a gap between the threshold and the canvas.
3. Warming from the outside and inside. For this, mineral wool or polystyrene is often used, which are laid directly on the wall or by the frame method. The main step is to determine the optimal thickness of the insulation. This will minimize heat loss as much as possible.
4. Floor insulation. Today, "warm floors" are very popular. They are used as a heat source. Of course, you can get by with the usual floor on the logs. Here you will have to lay the thermal insulation in the voids.

To create optimal conditions for living in a house, you should also think about replacing old radiators that are not working efficiently. The best option, by right, are considered bimetallic or steel structures. With their help, you can optimally warm the interior of the house. Thanks to simple actions, your home will become warm and cozy in the winter cold.

High-quality thermal insulation of a room is not only comfort and a way to extend the life of household utensils and personal items, but also a sharp reduction in heating costs (in winter) and air conditioning (in summer). Corner apartments, by definition, are the coldest in the house, since they have 2 walls at once that have direct contact with the atmosphere. We will deal with the most effective methods of wall insulation in a corner apartment from the inside in this article.

How can you do it:

Increase the degree of heating of the radiators. In a private house, this is possible if the circuit diagram is drawn up in advance so that the corner rooms are heated each along their own “thread”. But how effective and expedient it is is another question. And for an apartment building, this is excluded in principle.

On a note! Installing additional batteries in corner rooms may not give the desired effect. If the walls become warmer, then not much. And the corner will freeze, and in the future it will not work to get rid of the fungus.

Reduce heat loss. This is the most reasonable solution, not only due to high-quality sealing of window openings and blocks, but also with the help of additional finishing of the walls themselves.

Overview of wall insulation

It makes no sense to consider the editing technology, since the reader will be interested in the specifics of working only with the material that he chooses, and there is an article on each material on the site. But it is necessary to understand the features of use.

mineral wool

Conclusion - for residential premises it is not advisable to use mineral wool for internal insulation.

Styrofoam

In this case, it is worth using only its extruded variety -. Such plates are fixed on the wall by gluing. If necessary, additionally - dowels. Installation is simpler than mineral wool, but there are certain difficulties:

• You will have to qualitatively align the walls, since the foam boards are rigid, and they also differ in strict geometry.
• Surface vapor barrier will be kept to a minimum. Such material is certainly not suitable for wooden buildings, since the condensate formed on the base will lead to its intense decay. Such risks can only be reduced by providing high-quality wall ventilation, and this requires accurate calculations and additional costs.

A common drawback is that it will no longer be possible to fix something on the walls finished with these materials. For example, hang a shelf, a massive lamp, a picture, and the like.

polyurethane foam

Granular material for wall insulation from the inside is not used - only in liquid form. It has good insulating properties - hydro, noise, heat.

• Completely seals the base, so you can forget about the vapor barrier.
• Mounted by spraying. You will need special equipment and protective equipment. You can't do without the services of professionals. And although you will have to pay for such insulation from 65 rubles / m² (which, in principle, is inexpensive), it will not be possible to repair the heat-insulating layer, if necessary, on your own.

Plaster

Naturally, not any, but heat-insulating. Ready mixes of various modifications and manufacturers are on sale. The average price for 1 kg is about 15 rubles. There are many advantages - a thin layer, the possibility of self-application, high vapor permeability, good maintainability.

Minus - you will need high-quality waterproofing of the wall, since any of the compositions (to varying degrees) absorbs moisture. So, in the end, the coating will begin to soften and slide off the wall. This limits the scope of such plasters.

Conclusion - it is not advisable to use for rooms with excessive humidity.

"Liquid" insulation

If financial opportunities allow, you should pay attention to the products of the American company Mascoat. This material is not without reason called ultrathin insulation, or. According to experts, its 1 mm layer is equivalent in efficiency to mineral wool 0.5 cm thick. It is applied like ordinary paint, and at the same time, in addition to wall insulation, it provides high-quality waterproofing of the base.

Here are just some of the general characteristics of the product, as it is available in several versions.

• Recommended layer (mm) - 0.5.
• Consumption (l / m²) - 0.5 - 0.7.
• The temperature range in which the insulation does not deteriorate its properties (ºС) is from -65 to +265.
• Adhesion (%) - 100 in relation to any material. With this composition, you can paint the walls of a building, regardless of what materials it is built from - wood, reinforced concrete, brick, cellular concrete.
• It is applied on surfaces if their temperature is not less than +7. Therefore, from the inside, it is possible to process rooms in heated buildings all year round.
• There are no toxic components.
• The insulation does not burn.
• Excellent maintainability of the insulation, which does not require large-scale repairs to the premises.
• Guaranteed service life (years) - 15.

Therefore, the use of such liquid thermal insulation is not only expedient, but also extremely convenient. The only drawback is the high price. Euro bucket (about 20 liters) costs about 14,690 rubles. But if we take into account the meager consumption of funds, then 5-8 liters will be enough for one room.

In addition, you do not have to install a crate and spend money on other materials - waterproofing, adhesive (which is also expensive) and so on. If you calculate all the associated costs associated with the installation of traditional heaters, then the cost of such a special / paint will not seem too high.

There are several ways that allow you to additionally raise the temperature in the corner rooms. What to do?

• Rinse batteries. The need for this is determined by the difference in heating of the extreme sections. If it is significant, then, most likely, there are excess deposits on the inner walls.
• Check the position of the three-way valve (in old houses it is installed on the riser). Perhaps it is he who limits the flow of coolant through the radiator. It is easy to turn to the desired position. If the moving part is stuck, you can restore its mobility with the help of WD-40 (liquid wrench).
• Reinstall radiators. They should be placed as close as possible to the corner of the room, as this is the most problematic area of ​​the room.
• Check if the battery matches the parameters of the room. Sometimes the reason for the low temperature in the room is an insufficient number of sections. Unfortunately, not all builders are extremely experienced and conscientious people. They could also supply what is at hand, not particularly "worrying" with engineering calculations. The criterion is this - for 2 m² of room - 1 section. For corner rooms, a correction factor of 1.3 is applied.

For example, if the area of ​​​​the room is 10 "squares", then there should be at least 5 sections, for a corner 5 x 1.3 = 6.5. Therefore, at least 7 pieces.

• Stick an energy-saving film on the glass (or install). It will reduce natural light by no more than 2%, and heat loss through windows by 40%. Consequently, the temperature in the room will rise, which means that the walls will become warmer.

The article considers only the most suitable options for insulating a corner room from the inside, although there are much more heat-insulating materials. But not all of them are suitable for interior wall decoration, so the choice is somewhat limited.

What to consider

The main method of wall insulation is external. If there is such an opportunity, then first of all you should deal with the thermal insulation of the facade. And the arrangement of the inner layer is just an additional way to reduce heat loss.

The corner room always remains the coldest, despite the red-hot radiators. In order not to depend on the vagaries of the weather, it is worth considering how to insulate a corner apartment.

Where does the cold air come from

Corner apartments are located in the extreme entrances. The two walls that form the corner of the house are blown by cold winds. Such housing requires additional insulation.

If you insulate a corner apartment from the inside, it will become comfortable for living.

Most often the reason is in the walls. This can be either poor-quality brickwork, or cold bridges at the joints between the panels.

In low-rise buildings, you can finish the facade with foam. Outdoor work is also possible in high-rise buildings, but only for residents of the first floors. And even then, if there is no ban from the city authorities on changing the appearance of the house.

How to insulate a wall in a corner apartment from the inside

There are several technologies that can improve the microclimate of a corner apartment:

• Using expanded polystyrene is a simple and inexpensive way. But hanging shelves and cabinets cannot be attached to a wall insulated with any type of foam - the connection will be fragile.
• Application of mineral wool. This material crumbles easily, so indoors it needs to be lined with plasterboard or decorative panels.
• Insulation with plaster. In terms of environmental friendliness, this method is the most attractive.

Before laying any insulation, the walls should be cleaned of wallpaper and puttied.

Expanded polystyrene boards are glued using a special compound to a wall pre-coated with waterproofing. Large gaps between them foam. Then the wall is covered with reinforcing mesh and plastered. Mineral wool is fixed to the wall with wooden or metal slats. On both sides it should be surrounded by layers of vapor barrier.

From the author: hello, dear readers and amateurs to work with their own hands. Since the cold seasons are just around the corner, and indeed, the sleigh needs to be prepared since the summer, today I want to talk with you about one interesting topic, namely, how to insulate a wall in a corner apartment.

In general, the problem is different, and it would seem that the same corner apartments have the same disease - excessive cooling of the walls in contact with the outdoor environment, and, consequently, ultra-low temperature for normal living conditions.

Today we will talk not only about how to deal with this ailment in a corner apartment, but also we will analyze the reasons for all this happening, and what are the options for solving such problems.

Before we start, I want to point out something. As I understand it, you are a person who tries to do as much as possible with his own hands and not overpay for hired labor. Well, we have a lot of information for you that will help you in all your endeavors.

It is located on our portal. After studying it, you will no longer have any questions related to the independent production of finishing work. You will learn not only to cope with everything on your own, but also to choose the required material without falling for fakes.

You will learn how to choose a quality tool and, most likely, will begin to distribute advice on your own, and not look for it from someone else. In general, a real panacea for "handy" self-taught. Well, now it's time to move on to our topic.

Look, we have a problem - the cold in the apartment, and we need to solve it. Many resort to additional means of heating, including oil or infrared heaters, various thermal "dukes" and the like.

But there are those who approach the issue thoroughly. In general, there are several global ways to solve this problem, let's list them.

Wall insulation from the outside

It is allowed to insulate those walls that are in contact with the surrounding atmosphere only from the outside. Why this is required, we will discuss later.

Often this is the cause of the problem. Wooden windows do not have any seals, the wood has dried up a long time ago.

Installing small fans on existing batteries

In general, this method appeared not so long ago, and it is quite unusual. That is, you install one or more silent fans that run on a few volts or permanent magnets, such as those that cool your computer. Well, by blowing the battery, they better distribute warm air around the room, and, oddly enough, such a penny improvement increases the efficiency of radiators by about 30%. Because heat is usually distributed by thermal convection, and this method is not at all effective.

Why you can not insulate from the inside

It seems to us that everything is easy and simple: we bought a heater, sheathed the wall with it from the inside and enjoy the warmth, but it wasn’t there. If we dare to do this, then we will face the most terrible and invincible opponents of any apartment or house - condensate,.

All these problems arise because of the so-called dew point. This is the condensation of moisture from warm air or an environment that collides with cold air, and this very water is formed in the place of the strongest temperature difference.

That is, if we sheathe the walls with insulation inside the apartment, then this difference will have to be exactly in the place where the insulation joins the main wall. At first, everything there will simply become damp, and then it will begin to rot with the accompanying formation of huge pockets of mold.

In no case should you joke with such things, because the spores separated from the fungi begin to saturate the air in the apartment very strongly, which often leads to pulmonary diseases, pneumonia and aspergillosis, that is, poisoning with fungal spores.

In general, you understand that in no case should you do this, otherwise trouble cannot be avoided, so don’t even think about such a solution to the problem.

material for insulation

Now we will figure out what, in fact, the material we choose for the production of our work. In general, there are a huge number of them, but now we will list only the main ones and briefly describe what each of them is. So, the market gives us the following choice:

• wood concrete insulation - a mixture of debris in the form of sawdust, reeds, a variety of wood waste mixed with cement. The thing, I tell you, is so-so, although it is quite often used. But in order to achieve the desired result with this, you will have to apply a layer of 200-300 mm, and only in this case will you get something. And if only 20–30 mm, then there will be no sense in it;
• polyurethane foam. And this is the best of the best. To give you a better idea of ​​what it is, remember what mounting foam looks like. It's exactly the same, just sprayed on by a large machine and an industrial sprayer. Recently, it has been advertised very strongly, but the price is colossally huge, and overpaying by mounting such a layer is simply irrelevant. Well, let's wait for the time when the technology becomes cheaper, but for now let's resort to other methods;
• expanded polystyrene - and this is my favorite, because it combines many advantages. In terms of thermal characteristics, it is almost on the same level as polyurethane foam. Lightweight, won't rot, won't rot, easy to install. Yes, its price is slightly higher than, for example, that of mineral wool, but its properties are a hundred times more excellent and worth paying a little more for them;

• ecowool - again, a marketing ploy designed to make money out of thin air. They advertise it as a panacea for any thermal illness of the room, but, in fact, there is nothing good in it. This is the most common pulp, more precisely, recycled waste paper mixed with a solvent and a hardener and sprayed onto the walls. Yes, her properties are good, but for how long? The thing is that after getting wet, it ceases to be a heater and begins to rot, becomes a breeding ground for mold and excellent soil for mushrooms. In general, do not use under any circumstances;

• mineral wool - at first glance, an excellent insulation, because it is used in 80% of cases, oddly enough. But there are those who use the right cotton, and there are those who do not. In general, a heater called is a derivative of a special processing of clay. Therefore, its properties are appropriate. Yes, it warms well, but not for long, until the first wetting. And that's when the fun begins. Once saturated with moisture, it no longer loses it and does not dry out. Well, in this situation, it loses 90% of its insulating properties and becomes absolutely useless;

• glass wool - but this is already a thing. This is not mineral clay. Glass wool is made of potash glass, does not burn, is not afraid of water and does not lose its insulating properties when saturated with water. In general, the thing is cool, and its thermal coefficient is much higher than that of mineral wool. But there are also disadvantages: this is the price and the fact that after 20-30 years it begins to crumble and releases glass dust into the air. Therefore, if you want to install one, you will have to seal everything well.

As a conclusion, I can say the following. Better than Styrofoam or its older brother - extruded polystyrene, which is a little steeper, but more expensive - you will not find. Therefore, you can safely go to the store just for him.

Purchase of material

Now let's figure out what you have to buy from the material in order to produce insulation. You will not need so much, but know that all this will definitely cost you a pretty penny. So the shopping list is as follows:

• foam or extruded polystyrene foam. You will need to tightly sheet the entire surface of the walls outside your apartment, but that's not all. In addition, you need to make a call both down and up from your apartment. Sunset should be at least 50 cm, and best of all 70-80. This is done because, by covering only your area, you will not protect your corners from being hit by cold, and they will freeze through, as if you did not insulate anything;
• a balloon with polyurethane foam - you will need it for gluing the seams between the foam sheets. If the seams are not passed through with such foam, but simply forgotten about, then in these places you will experience cooling and heat loss, which negatively affects the overall effect of the coating;
• fastening "fungi" - needed to fix the foam sheets to the wall. These are purely plastic mounts, but there are other options with different steel cores. But their use, so to speak, professional, does not give any advantages, so you should not overpay;
• adhesive tile, for work on facades of buildings. We need it for gluing sheets of insulation to the walls. Remember, they should be glued, and not just nailed to the mounts. This way you eliminate any air gap and minimize the chances of condensation between the layers. Yes, and with this design, the efficiency of the use of insulation increases;
• deep penetration primer - to improve the adhesive properties of both the wall in general and the insulation sheets used;
• wide mesh serpyanka, fiberglass mesh, metal reinforcing mesh in rolls, or fiberglass. Required to create a reinforcing layer that will support the final, finishing coating of the insulation;
• paint if you are going to give a beautiful aesthetic to the wall. While leaving a gray patch against a painted house, the Housing Authority won't let you, so you'll have to buy the paint anyway.

Everything is clear with the material, and now about what you need to do next.

Hiring specialists and monitoring the progress of work

Now about what we still do with such a global problem. We can’t do anything with our own hands here, because work at height is extremely dangerous, and it is forbidden to carry it out to persons who have not completed the appropriate courses, have not passed exams and have not received a certificate of the right to work at height.

I know that most people who turn to this topic live in a panel house, because often such problems occur there. And such houses are only high-rise, and, most likely, you do not live on the first floor. And in this case, all that remains for us to do is to hire a specialized team of workers.

It is best to hire employees of legal firms, only they give a guarantee for their work, and if necessary, eliminate all defects that have arisen through their fault solely at their own expense.

And in order for them to do everything right, you must first acquire the material yourself and control their work. The material is bought because the one they use is the cheapest and not of high quality. And they rip off for him soundly.

Although monitoring them may not be necessary, they are still desirable, because they can omit some points that are mandatory and must be strictly observed. Now let's write down what exactly you should control:

• employees must be equipped with protective equipment, work in overalls, have a tool belt and a special belt for working at heights. Plus, good slings, cradles and insurance;
• they must remove all peeling paint from the wall, and not only from your territory, but also make the entry that we talked about above;
• then they need to treat the walls and insulation panels on both sides with a deep penetration primer;
• glue foam sheets on your walls, with an approach to the neighboring ones, while gluing the seams with mounting foam;
• paste over the sheets with reinforcing mesh;
• apply, or rather, plaster the entire insulation with a thin layer of tile adhesive;
• paint.

That's all, friends. You know, I understand that you want to save money and do it all yourself, but it's not worth risking your life over a small amount of money. Understand, you know nothing about knots, slings, insurances. And falling from a height of only 9 meters, that is, from the third floor, is fatal in 90% of cases, so please do not take risks.

And finally, I want to note that we do not write professional editing literature, we just introduce you to the topic, therefore we are not responsible for your actions. Good luck!
