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:
- 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.
- 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.
- Extruded polystyrene foam. It has a long service life and is uninteresting to rodents.
- - very durable, which makes it possible to mount it with self-tapping screws. Its only downside is that it is quite expensive.
- 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
- 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.
- 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.
- 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:
- 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.
- 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.
- Particular attention should be paid to the depth of the frame. It should be equal to the thickness of the insulation.
- 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.
- 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.
- 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.
- Frame sheathing. After the insulation and vapor barrier are installed, drywall is mounted. OSB boards are also used for sheathing the frame.
- A reinforcing mesh is applied to the drywall joints and puttied. After that, the entire surface is leveled by applying putty.
- 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:
- 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.
- 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.
- 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:
- 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.
- 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.
- Putty and finishing. When the thermal insulation layer is installed, 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:
- 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.
- 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.
- 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.
- 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.
Residents of houses very often face the problem of moisture and mold on the walls, especially in the corners of houses. Often this is due to miscalculations in construction, in which the thermal conductivity of the materials used to build and finish the house, and the internal temperature of the rooms, were not taken into account.
Peculiarities
If in winter time condensation forms on the inner wall of the room in the form of water droplets, and later mold, this indicates insufficient thermal insulation of the walls or the material from which they are made.
In addition, in the winter season, if there are small cracks in the corners, walls and corners can even freeze due to the flow of very cold air. The reason for this can be both the gaps between the slabs or bricks, and the voids in the slabs themselves.
As a result of this unpleasant phenomenon:
- glued wallpapers get wet and fall behind;
- walls painted with water-based paint are covered with unpleasant red stains;
- the layer of plaster is gradually destroyed, no matter how strong and high-quality it may be;
- fungus and mold appear on the walls.
You can eliminate these shortcomings by insulating the walls from the inside. For example, laying heating pipes vertically along the corners or making an additional bevel of plaster in the corners of the room. However, the most effective and efficient way is the external insulation of walls and corners, which eliminates the very reason - poor thermal insulation.
Basic ways
Modern industry offers several options for insulation, differing in the use of various materials and the method of their application.
- The use of "warm" plaster. In this case, foam granules are added to the plaster instead of sand. This significantly reduces the thermal conductivity and the overall weight of the plaster layer. Its application reduces the overall thermal conductivity of walls and corners, while allowing the walls to breathe, which stops the formation of condensation on the walls.
- The use of liquid thermal insulation. Produced by many manufacturers. They are a liquid solution, which includes microspheres of ceramics, glass or silicone. They have excellent thermal insulation, allow you to work in hard-to-reach places, including in the corners of houses.
- Installation outside foam blocks, mineral wool or expanded polystyrene. This method has the strongest thermal insulation characteristics, unlike the previous two. At the same time, the walls of the house are completely closed from the outside with light heat-insulating blocks that are not subject to corrosion and have excellent resistance to temperature extremes and high humidity.
- Thickening of brickwork. This very simple and effective method is very often used even at the stage of building houses and visually distinguishes the building by the fact that additional brick laying was carried out at the corners of the houses. Additional laying can be carried out later, if the architecture of the building itself allows it.
How is thermal insulation carried out?
Among the many ways of warming, everyone chooses his own - the most convenient and affordable option. Most often, it is necessary to insulate the walls and corners in the corner rooms, since in them, as a rule, two walls go outside the house. However, there are some subtleties when using certain materials.
The very process of insulating corners and walls can be carried out even at the stage of building a house and design solutions for decorating rooms. For example, only rounding the inner and outer corners of the facade can reduce the temperature difference between the wall and the air inside the room by up to 20%.
Installing fixtures in plasterboard panels directly in the corners of the room provides heating of the walls and shifting the dew point. This eliminates the cause of the appearance of wet walls in the room.
In addition, when building wooden houses, one should take into account some features of log cabins in the "paw" and in the "bowl". So, one of the disadvantages of a log house in the "paw" is that it is a source of increased heat transfer, and hence heat consumption. As a result, increased cooling of the inner surface of walls and corners, the formation of moisture on their surface.
Using penofol for insulation, it should be noted that the main thing when using it is to create an air cushion between the wall and the material itself. If this condition is not met, then the insulation using penofol will not work and will not be able to perform its functions. In addition, when insulating from the outside, the penofol itself sits on three frame support grids.
To strengthen with foam plastic in the panel method, it is necessary to calculate the area of \u200b\u200bthe material with a thickness of 5–10 cm so that it covers the entire surface of the outer wall with a margin. The panels themselves, cut to size, are fixed to the walls and log cabins with a special glue. After the entire foam is fixed, and the glue has dried, it is necessary to glue the fiberglass mesh overlap on the foam sheets to give mutual strength to the glued sheets.
Then the foam sheets are covered with a special putty to protect against moisture ingress between the sheets. For the final coating, structural putty or facade paint is used.
With an uncertain source of thermal insulation violations, modern technologies can come to the rescue. In this case, it is necessary to use thermal imaging of the room. Experts in this field will be able to accurately determine the place of violation of thermal insulation and give recommendations on how to eliminate the identified shortcoming.
For information on how to properly insulate a house from the outside, see below.
Conventional heating can not always cope with its task, especially if the apartment is corner. In such an apartment, both walls are in contact with the street, so the cold penetrates to a greater extent than when the apartment is placed in the middle of the house.
Even heating batteries cannot cope with such a problem. Owners in this case need to properly insulate their home. This can be done both from the outside of the walls, and from the inside. This article will consider the question of how to insulate a wall in a corner apartment from the inside.
Features of the corner room
It is often very cold in corner apartments. Corner rooms are always more frozen than rooms that are located in the middle of the house. Due to this, heat losses occur, it becomes quite cold in the room in winter, even the appearance of dampness, mold and other troubles is possible.
In corner rooms, 2 batteries are often installed to maintain the required temperature, but walls can freeze through. Condensation appears on it, which leads to the following troubles:
Avoiding such problems and being in a warm room in the winter will help. Before starting work, you need to determine and choose the right materials to be used.
For insulation today there are a lot of materials, but they are all designed for different jobs.
Some are used only for external work, others are used exclusively inside the building.
How to insulate depends on many factors. There are no universal materials, all heaters have their pros and cons. All heaters must be:
- With high thermal conductivity.
- Airtight.
- Absorbent moisture.
- Eco-friendly.
- Burn resistant.
- With high service life.
| Name | Description | Advantages | disadvantages |
|---|---|---|---|
| Mineral wool | The most common insulation, which is made from basalt. | It does not lend itself to combustion, and if it comes into contact with fire, it does not emit harmful substances. Easy to install without special skills and experience, the material is plastic. | Mineral wool is quite weighty, and after a while it can be deformed. Susceptibility to moisture. |
| Styrofoam | Insulation plates are light and safe for humans. The material can be used for indoor and outdoor use. | Low material cost and easy installation. Withstands strong temperature fluctuations and retains its properties in the range from -180 to +80 degrees. The service life is several decades. | May create condensation inside, and therefore not suitable for wood. The heater burns very well. |
| polyurethane foam | This is a foam that retains heat well, because most of its composition is gas. It is applied from special equipment, sprayed onto the wall. | High noise insulation performance, does not burn. The operating period is measured in tens of years. | Compared to other materials, it has a high cost. Polyurethane foam is applied from special equipment directly to the wall in liquid form, after which it hardens. For insulation, you will need to hire specialists. |
Having studied the features of the materials and choosing the best option for yourself, you can begin to insulate the corner apartment. The instructions for working in and at home are described below.
Performing independent installation, you need to carefully lay each layer of insulation. Any mistake can provoke the appearance of mold on the walls.
Insulation of internal walls in a panel house
Lay the insulation panels on the waterproofing layer To carry out the work, you will need to prepare the walls and gain access to the base. It is recommended to carry out the work before the start of the repair. Sometimes, a reasonable panel house.
If the insulation is carried out after the relevant work, then tiles, wallpaper and other finishing materials are removed from the walls.
The laying of mineral wool is carried out in 2-3 layers, this will allow the seams of the first layer to be closed with a slab of the next layer.
Insulation of internal walls in a brick house
Insulation is mounted on glue Work in a brick building has some differences compared to a panel house, but the technology is simple and does not require special skills to perform.
Consider the option of wall insulation inside the room using polystyrene foam or:
- Initially, the walls need to be prepared. There must be plaster on the bricks, if there is no such mixture, then the bricks must be plastered.
- The walls need to be leveled and all existing defects removed. Further, the base is primed with means to which antiseptics are added, you can use a special primer.
- Glue for polystyrene foam must be diluted according to the instructions on the package. The finished mixture is applied to the walls using a conventional and notched trowel.
- Sheets of insulation are glued to the wall and pressed tightly to the base. When insulating internal walls, dowels are not required to fix the plates.
- The plates are stacked tightly one to the other. There should be no gaps between them. The denser the pressing of the material to the wall and to each other, the better the thermal insulation properties will be. During installation, use a level to bring out a flat plane. For more information on how to insulate from the inside, see this video:
In case of formation of gaps between the plates, they must be filled with mounting foam.
Before starting the insulation of rooms in a corner apartment, it is necessary to select the material depending on the material of the walls.
For brick, the installation procedure and insulation are different from panel buildings.
After reviewing the information in the article, it will be possible to carry out work quickly and without paying for the services of expensive craftsmen.
Of course, do not buy a cold apartment in a high-rise building at all.
You can determine a cold apartment or a warm one by several observations:
- The first point is that if the owners are dressed warmly (they are wearing sweaters or sweaters), it means that the apartment is cold.
- The second point is to compare the outer and inner sides of the wall. Are they the same temperature or not?
- The third moment is to stand in the hallway or on the landing and go into the apartment. Then, listening to your feelings, compare the temperature difference. If the differences are not felt, then you need to beware.
If the apartment is located on one of the extreme floors, then the cause of the cold may be poor thermal insulation of the roof or foundation. the reason for the cold in the apartment can be accelerated poor-quality masonry, which the builders did in a hurry. In panel houses, most likely, the joints between the panels are not sealed.
How to insulate the walls of the apartment
In this case, of course, there are also disadvantages, such as rearranging furniture and things that are in the room. A noticeable reduction in living space in the room - this is especially felt when two walls are reduced. And of course, it is especially troublesome to temporarily isolate the wall from the heating system.
How to insulate walls from the outside
Consider this option - you live in a multi-storey building on the ground floor in a corner apartment. In this case, a tower is not needed to insulate the apartment, and all work is possible. Therefore, you can consider the option of how to insulate the walls in the corner room from the street.
To do this, we use the most common insulation - foam. It is better to choose the thickness of the foam yourself, depending on the region of residence. It can vary from 5 to 10 centimeters. you need to take a little more so that the foam blocks the dimensions of the wall with a margin. Then you need to fix the starting galvanized profile and start work. Apply a few patches of tile adhesive to each sheet and press the foam firmly against the wall.
For greater strength, the sheet must be fixed with five umbrella dowels (simply called fungi) in the corners and in the center. Holes for dowels can be made with a puncher directly through the foam. After that, we apply with a wide spatula a thin layer of tile in it, a fiberglass mesh resistant to alkali with a cell of 5 millimeters. Then we cover the foam with putty and plaster as usual.
Yes, all this is good if we are on the ground floor. And if on the second and higher, and there is no way to insulate the walls from the outside, then we move on to another option.
How to insulate walls from the inside
Today there are many solutions. In addition to those problems with wall insulation, which we will consider a little lower, there are others.
The first thing that comes to mind is to insulate a freezing corner with batteries. You can, of course, move the heating radiator to this place, after checking the number of sections on the radiator. It is desirable to increase them, since the coefficient for is higher than for ordinary residential premises, in which one section per two square meters is used. For corner rooms, a coefficient of up to 1.3 is applied, and in cold regions it is even higher - up to 2.0. So, all our troubles with heating devices did not lead to the desired result.
Let us then pay attention to the following points. For example, you feel a cold air flow from under the window. In addition to installing good metal-plastic windows, you can use insulation as a foam seal. But if this did not help, then the question remains open, how to insulate the room?
Let's try to find other solutions. Fortunately, there are several of them. Walls can be insulated with mineral wool, polystyrene foam and polystyrene. Let's consider each option separately.
Warming with mineral wool
Glass wool is an excellent mineral sealant, which consists of many small fibers and is made from glass waste. Glass wool has a number of advantages, such as quality, light weight, long service life and environmental friendliness. In addition, cotton wool on the walls reduces noise well.
Cotton mats are mounted as follows. First of all, we apply waterproofing from a film or primer to the wall. Waterproofing is a very important factor, because wet glass wool loses its thermal insulation properties. Then we mount the frame, where we will lay the insulation. It is most convenient to make a frame from wooden slats. We seal the joints between the glass wool mats with adhesive tape, and the remaining gaps can be blown out with mounting foam.
Finally, we apply a second layer of insulation and glue the mounting grid.
Precautions: do not allow even small particles of glass wool to enter the eyes and respiratory organs.
It is best to work with this material in glasses, with a respirator and in cotton gloves.
Insulation with foam
You can use the insulating substrate "Polyform" under the wallpaper, which protects against cold and fungus. As well as ultra-thin thermal insulation called "Mascoat".
Insulation "electric warm floor"
The essence of this is to eliminate moisture that accumulates inside the wall. The insulation design will be somewhat different from the first two cases.
In simple terms, this is a wall on which a mat of electric insulation is attached. Then comes - either cotton wool or polystyrene. And then the finish itself. The scheme of operation of the "warm floor" is elementary simple. Insulation heats the wall, which contributes to the impossibility of moisture formation inside the wall itself. The second big plus is that the electric heater protects the room from heat loss.
As you can see, each insulation option has its pros and cons. Which one to choose is up to you. One thing is important, if you decide to do everything yourself, you need to make an accurate calculation of consumables, as well as future energy costs, in the case of using an electric heater. The rest is a matter of technique.
Foreword. In this article, we will consider why a room in a corner apartment should be insulated: the causes of cold and freezing of the walls in the room. What heaters should be used for work and we will give detailed instructions for the thermal insulation of a room in a corner apartment of an apartment building with our own hands.
The problem of a cold room in an apartment exists with many owners of living space in apartment buildings. Often this is due to the location of the apartment - one of the walls of the room is the outer wall of the house or is adjacent to the wall of the cold entrance. If we have already considered the question of how to insulate the wall of the entrance, then the question of how to insulate a cold room with your own hands is still open.
Why is it necessary to insulate a corner apartment
Of course, the best way to get rid of this problem is not to buy a corner apartment in a high-rise building. You can determine at the selection stage whether a cold room in an apartment or a warm one can be done in simple ways. Firstly, if the owners of the apartment are dressed warmly in winter, then the room is cold. You can also stand in the corridor for a few minutes, and then go into the room and compare the temperature difference, listening to your feelings. If you feel a temperature drop, then you should be wary.
If an apartment in a multi-storey building is located on the first or last floor, then the cause of the cold in the entire apartment can be large heat losses through the basement or attic. With this problem, you can also quite simply figure it out on your own - insulate the floor in the apartment on the ground floor, and if your living space is on the top floor of the house, then you should insulate the ceiling in the apartment.
In brick houses, a common cause of cold indoors can be poor-quality masonry of the outer walls, which the builders did. In panel houses, builders may not properly seal the joints between reinforced concrete panels. There are several simple ways to solve the problem of thermal insulation of walls in a corner apartment with your own hands. Let's consider all these methods in more detail.
Ways to insulate a room in a corner apartment
It is believed that the external insulation of the facade with foam plastic is more effective. But often this method will not work. For example, it is forbidden to change the facade of an apartment building at the legislative level, or the insulation of a corner room in an apartment from the outside with foam plastic, foam plastic or mineral wool is not economically profitable or impossible from a technological point of view.
Do-it-yourself internal insulation of a corner room consists in thermal insulation of all surfaces without exception - the walls of the corner room, the ceiling and the floor. This method has its drawbacks in the form of rearranging the furniture in the room during the repair, as well as a significant reduction in living space.
To insulate a corner room in a brick or panel house from the outside, you will need scaffolding and tools, and you can do all the work yourself. For external thermal insulation, you can use the most inexpensive and popular insulation - polystyrene foam, as well as extruded polystyrene foam or mineral wool. All these materials differ in their characteristics and applications.
How to insulate the walls of a room in a corner apartment
The thickness of the insulation depends on the region of residence, the material of the walls of the house (brick or panels) and can vary from 5 to 20 centimeters. In order not to make a mistake in the thickness of the heat-insulating layer, use the wall insulation thickness calculator online on our website. Don't forget to buy insulation with a small margin to cover the entire wall completely.
How to insulate a room in a corner apartment from the outside
For the installation of thermal insulation, it is necessary to fix the starting profile exactly in level. Next, we lay the insulation, applying glue to each sheet of foam or foam plastic and pressing it against the wall. For reliability, the plates can be fixed with dowels-umbrellas. Seams must be made in a checkerboard pattern and carefully foamed in the presence of gaps.
After installation, a plaster mesh is glued to the insulation, a primer is applied and the entire structure is covered with facade putty. In more detail about the insulation of the facade with polystyrene foam and how to insulate the house with foam plastic from the outside, we considered earlier. When insulating a corner room in an apartment outside with mineral wool, it is necessary to make a crate.
Mineral wool is laid between the guides made of wood bars. The distance between which should be 1-2 centimeters less than the insulation boards for laying stone wool in the spacer. Before laying the mineral wool, the wall is closed with a moisture-proof membrane. After laying the mineral wool on the wall, the entire structure is closed with a vapor barrier on the right side and sheathed with PVC panels.
How to insulate a room in a corner apartment from the inside
All of the above methods are good if the apartment is located on the first or second floor. But if the apartment is higher, then we turn to the option of warming from the inside of the room in the corner apartment with our own hands. Today, there are many heat-insulating materials and technical solutions for self-insulating a corner room in a panel house at minimal cost.
But the first thing to start with is to check the number of sections on the radiator in the room. It is advisable to increase the power of the radiator by adding several sections. In simple rooms, it is customary to put one section per two sq.m. For corner rooms in apartment buildings, the coefficient is higher than for ordinary premises and is 1.3, and in cold regions this coefficient reaches 2.
When installing windows, pay special attention to the insulation of the slopes from the outside. In addition to installing high-quality metal-plastic windows with double glazing, the window sill should be insulated so that cold air does not blow through it. But besides this, it is necessary to insulate the wall inside in the corner room, which is adjacent to the entrance or the outer wall of a brick or panel house.
Insulation of a room in a corner apartment with mineral wool
Mineral wool is an environmentally friendly insulation, consisting of fibers, the material is made from rocks by melting them. Characteristics of mineral wool are good: light weight, low thermal conductivity and sound insulation, long service life. Thermal insulation mats are mounted on the wall between guides made of wood bars or a metal profile for drywall.
The waterproofing of mineral wool is an important factor, since a moistened basalt wool insulation loses its thermal insulation properties. Therefore, before mounting the frame, it is necessary to cover the wall with a wind and moisture protective film. It is more convenient to make a frame from wooden slats with a width equal to the thickness of the thermal insulation and a distance between them equal to the width of the insulation mats minus 1-2 cm.
After laying the mineral wool, a vapor barrier or a superdiffusion membrane is laid, rails are stuffed onto the guides to create an air gap. This is necessary so that moisture evaporates from the surface of the superdiffusion membrane. Next, drywall, OSB boards or plywood are stuffed onto the rails. It is better to work with mineral wool with glasses, gloves and using a respirator.
Insulation of a room in a corner apartment with foam plastic
Styrofoam insulation is more common due to the availability of polystyrene foam and the ease of its installation. The main characteristics of foam are lightness, low thermal conductivity and ease of installation. For residential premises, you can buy expanded polystyrene, which, during production, has added substances that prevent the ignition of the foam.
Before laying the insulation boards, liquid waterproofing is applied to the leveled wall. Tile adhesive is applied to the foam sheets with a comb spatula, and then the sheet is pressed against the wall. After covering the entire wall area, a mounting mesh is glued on top and putty is applied to it. After the putty has dried on the wall, you can paint the surface or paste over with vinyl wallpaper.
But when insulating a room in a corner apartment with foam plastic, foam plastic or other moisture-proof material, for example, foil foam, there is a risk of mold and mildew between the insulation and the wall. Since the wall in a brick or panel house stops breathing and is constantly in a cold circuit (heat access to the wall will be blocked by a layer of insulation).
Which insulation to choose for a room in a corner apartment in a panel house is up to you. It is only important to familiarize yourself with the video instruction on this topic and make an accurate calculation of the required thickness of insulation.
