The corner apartment has some peculiarities. A clear drawback 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 the 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. It's worth starting with the choice of insulation.

Types of insulation
Today on the market there is 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 correctly approach the choice.
How to insulate a wall in an apartment from the inside, you will need:
- Mineral wool. Marketed as mats and rolls. Depending on the raw materials used in 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. Foam insulation lasts from 10 to 15 years. They are protected from rodents from the mesh.
- Extruded polystyrene foam. It has a long service life and is not interesting to rodents.
- - very durable, which makes it possible to mount it with self-tapping screws. Its only drawback is that it is quite expensive.
- Polyurethane foam and penoizol. Liquid insulation has the same properties as expanded polystyrene.
Polyurethane foam is applied to structures by spraying. As for penoizol, it is mainly used 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 can withstand high temperatures. It is easy to mount on the wall without any special tools or 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.
Selection 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. It is very popular among consumers, used for thermal insulation of walls from the inside. Plates have special grooves, which allows making their joints airtight. As a result, the risk of cold bridges is minimal.
- Polyurethane foam. Allows you to quickly insulate structures. Liquid insulation has high technical characteristics. A seamless coating is made from it.
The disadvantage of polyurethane foam is that it requires a special technique to apply it. All work is carried out in a special protective suit using gloves, glasses 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 thermal insulation layer from moisture and thereby extend its service life.
Warm plaster, cork wallpaper, thermal paint and foamed polyethylene are sometimes used to insulate the 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
Insulation of walls 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, installation on the walls of a frame made of a metal profile or wooden slats is performed. After laying the insulation, the frame is sheathed with plasterboard. Any top coat can be used over it.
Important! The frame method is rarely used in panel and monolithic houses. This is due to the complexities of mounting the frame.
Brick buildings
For wall decoration in a brick house, foam plastic, mineral wool or penoplex are widely used. It can be both slabs and roll 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:
- Installation of the frame. 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. Vertical frame elements are installed between them. The distance between them should correspond to the width of the slabs or roll.
- Particular attention should be paid to the depth of the frame. It should be equal to the thickness of the insulation.
- Insulation from the inside. After the frame is built, the 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 is carried out between the vertical guides.
- With tiled materials, the situation is simpler. The required number of slabs is placed in the voids. At the end, he slices the material to fill the remaining space. If gaps have formed, then they are filled with polyurethane foam.
- Vapor barrier. A vapor barrier film is applied over the insulation. This will protect it from fumes. This is especially important when using mineral wool.
- Frame sheathing. After the insulation and vapor barrier are mounted, drywall is mounted. Also, OSB plates are used for sheathing the frame.
- A reinforcing mesh is applied to the joints of drywall and putty. After that, the entire surface is leveled by applying a putty.
- Finishing finish. At the final stage, decorative finishing is performed. Wallpaper is often 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 glued 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 polyurethane foam.
Electric floor technique
With the help of electric wall heating, you can create a comfortable living environment 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 thermostat. Thermal insulation is installed using different methods.
Important! Before insulating the end wall in the apartment with a cable, foamed polyethylene is applied to it. It is not recommended to use materials that conduct current.
Installation of cables through the "warm floor" system is carried out in pre-prepared grooves or directly on the structure. In the latter case, the heating elements are secured with mounting tape after application. A thermostat is connected to them. The system starts up one month after the plaster has been applied.
End walls
To resolve the issue of how to insulate the end wall in an apartment, mineral wool or foam is often used. In such cases, installation work is carried out using different technologies.
The foam is mounted directly on the wall. Before carrying out 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.
Thermal insulation from the inside based on mineral wool is carried out using frame technology.
Sequence of work:
- With the help of a metal profile and rails, a system with voids is made, into which the insulation is laid. The distance between the vertical slats must match the width of the roll.
- When the frame is mounted, the cotton wool is laid. A vapor barrier film is laid on top, which will protect the material from the accumulation of condensation.
- The frame is sheathed with plasterboard. The surface is putty, finishing is carried out.
Thermal insulation of the end wall can be carried out in any available way. 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, this concerns the high-quality preparation of the structure for cladding.
Installation of thermal insulation takes place in several stages:
- Preparation. Before carrying out thermal insulation, the structure is carefully prepared. The surface is cleaned and treated with a soil solution. If there are cracks and other defects, then they are eliminated with putty or polyurethane foam.
- Insulation of a panel house from the inside. Styrofoam is often used for this. This is quite simple to do. You just need to apply the adhesive to the wall and attach the material. To ensure reliable fixing of the plates, experts recommend additionally using special dowels.
- Putty and finishing. When the heat-insulating layer is installed, the wall is completely plastered 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 cladding panel houses, special attention should be paid to the condition of the surface. This is especially true for the joints between the panels. Otherwise, foam insulation will not give a high effect.
Finishing corners in the apartment
To insulate a corner room in a brick or panel house, it is necessary to carry out a number of activities. With certain skills and knowledge, all work can be done by hand.
Thermal insulation of an apartment is carried out in the following sequence:
- Insulation of windows and balconies. In this case, we are talking about glazing. To protect the premises from heat loss, it is necessary to exclude the main sources of cold and drafts. The best solution would be to install plastic windows. In this case, the structure must have at least two chambers.
- Insulation of the front door. It is also a common cause of heat loss. If the apartment has an old door, then it is better to replace it with a modern model, which has high heat and sound insulation properties. Particular attention should be paid to the cracks around the door frame, there should be no gap between the threshold and the canvas.
- Insulation from the outside and inside. For this, mineral wool or foam 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. Warm floors are very popular today. They are used as a heat source. Of course, you can do with the usual floor on the logs. Here you will have to lay the insulation in the voids.

To create optimal living conditions in the house, you also need to think about replacing old radiators that are not working efficiently. Bimetallic or steel structures are rightfully considered the best option. With their help, you can optimally warm up the interior space 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 the formation of moisture and mold on the walls, especially in the corners of houses. This is often due to miscalculations in construction, in which the thermal conductivity of the materials used for the construction and decoration of the house and the internal temperature of the rooms were not taken into account.
Peculiarities
If, in winter, condensation forms on the inner wall of the room in the form of water droplets, and later on - 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 through due to the flow of very cold air. The reason for this can be both gaps between slabs or bricks, and voids in the slabs themselves.
Due to this unpleasant phenomenon:
- the pasted wallpaper gets wet and falls off;
- 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 is;
- fungus and mold appear on the walls.
You can eliminate these shortcomings by insulating the walls from the inside. For example, by laying heating pipes vertically along the corners or by making an additional bevel of plaster in the corners of the room. However, the most effective and efficient way is external insulation of walls and corners, which eliminates the very reason - weak thermal insulation.
Basic ways
The modern industry offers several options for insulation, which differ in the use of a variety of materials and the method of their application.
- Application 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 use 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 insulation. Produced by many manufacturers. They are a liquid solution containing 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 of foam blocks, mineral wool or expanded polystyrene. This method has the strongest thermal insulation characteristics, in contrast to the previous two. At the same time, the outside walls of the house are completely covered 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 in that additional brick laying was carried out at the corners of the houses. Additional installation can be carried out later, if the architecture of the building itself allows it.
How is thermal insulation carried out?
Among the many methods of insulation, everyone chooses their own - the most convenient and affordable option. Most often, walls and corners in corner rooms have to be insulated, since in them, as a rule, two walls go outside the house. At the same time, there are some subtleties when using certain materials.
The very process of warming corners and walls can be performed even at the stage of building a house and design solutions for decorating rooms. For example, only rounding off the inside and outside 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 will heat the walls and shift the dew point. This eliminates the cause of the appearance of damp walls in the room.
In addition, during the construction of wooden houses, one should take into account some of the features of log cabins in the "paw" and in the "bowl". So, one of the disadvantages of a "paw" log house 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 borne in mind 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 insulation using penofol will not work and will not be able to perform its functions. In addition, when insulated from the outside, the penofol itself sits on three frame support grids.
For reinforcement with foam plastic with the panel method, it is necessary to calculate the area of the material with a thickness of 5–10 cm so that it covers the entire surface of the outer wall with a margin. The cut-to-size panels themselves are fixed to the walls and log cabins using special glue. After all the foam is fixed and the glue has dried, it is necessary to overlap the fiberglass mesh 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 penetration between the sheets. For the final coating, use a structural putty or facade paint.
With an uncertain source of thermal insulation damage, 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 deficiency.
For information on how to properly insulate a house from the outside, see below.
Conventional heating cannot 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 inside 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 always freeze more strongly, in contrast to the 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, it is even possible that dampness, mold and other troubles appear.
In corner rooms, 2 batteries are often installed to maintain the required temperature, but the walls can freeze through. Condensation appears on it, which leads to the following troubles:
Avoiding such problems and staying in a warm room during the winter will help. Before starting work, you need to determine and correctly select the materials that will be used.
There are a lot of materials for insulation today, 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 own pros and cons. All heaters must be:
- With high thermal conductivity.
- Airtight.
- Moisture wicking.
- Eco-friendly.
- Resistant to combustion.
- With a high operational life.
| Name | Description | Dignity | disadvantages |
|---|---|---|---|
| Mineral wool | The most common insulation 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 assemble without special skills and experience, the material is plastic. | Mineral wool is quite weighty, and after a while it can deform. Susceptibility to moisture. |
| Expanded polystyrene | Insulation plates are lightweight and safe for humans. The material can be used for indoor and outdoor use. | Low material cost and ease of installation. Withstands strong temperature changes and retains its properties in the range from -180 to +80 degrees. The service life is several decades. | It can create condensation inside, which means it is not suitable for wood. The insulation 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 on the wall. | High noise insulation performance, does not burn. The operational 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. Instructions for working in and out of homes are described below.
Performing independent installation, you need to carefully lay each layer of insulation. Any slip 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 starting the repair. Sometimes, it is reasonable to have a panel house.
If the insulation is carried out after the appropriate 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 Working 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 expanded polystyrene or:
- Initially, the walls need to be prepared. There should be plaster on the bricks, if there is no such mixture, then you need to plaster the bricks.
- The walls need to be leveled and all existing defects removed. Further, the base is primed with agents to which antiseptics are added, you can use a special primer.
- Polystyrene foam adhesive must be diluted according to the instructions on the package. The finished mixture is applied to the walls using a conventional and notched trowel.
- Insulation sheets are glued to the wall and pressed tightly to the base. When insulating interior walls, you do not need to use dowels to fix the plates.
- Plates are stacked tightly to one another. There should be no gaps between them. The tighter the material is pressed against the wall and against each other, the better the thermal insulation properties will be. During installation, you should 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 gaps between the plates, they must be filled with polyurethane 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 bricks, the installation procedure and insulation is different from panel buildings.
After reviewing the information in the article, it will be possible to carry out the work quickly and without paying for the services of expensive craftsmen.
Of course, not to 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 moment - if the owners are dressed warmly (they are wearing jackets or sweaters), then it is cold in the apartment.
- The second point is to compare the outer and inner sides of the wall. Whether they are the same temperature or not.
- The third point is to stand in the corridor 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 be on your guard.
If the apartment is located on one of the outer floors, then the reason for the cold can be poor insulation of the roof or foundation. the reason for the cold in the apartment can be the 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 can you insulate the walls of an apartment
In this case, of course, there are also disadvantages, such as rearranging furniture and things that are in the room. A noticeable decrease in living space in a room - this is especially felt when two walls are reduced. And of course, it is especially troublesome - it is the temporary insulation of the wall from the heating system.
How can you insulate the walls from the outside
Consider this option - you live in a multi-storey building on the first 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 a 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 on your own, depending on the region of residence. It can range from 5 to 10 centimeters. it is necessary to take a little more so that the foam with a margin overlaps the dimensions of the wall. Then you need to fix the starting galvanized profile and start working. 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 (in a simple way called mushrooms) in the corners and in the center. Holes for dowels can be made with a puncher directly through the foam. After that, apply a thin layer of alkali-resistant glass mesh with a cell of 5 millimeters with a wide spatula. Then we cover the foam with putty and plaster as usual.
Yes, all this is good if we are on the first 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 can you insulate the walls from the inside
Today there are many solutions. In addition to those problems with wall insulation, which we will consider below, there are others.
The first thing that comes to mind is to insulate the freezing corner with batteries. You can, of course, move the heating radiator to this place, having previously checked 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 is used for two square meters. For corner rooms, a coefficient of up to 1.3 is applied, and in cold regions even higher - up to 2.0. So, all our troubles with heating devices did not lead to the desired result.
Then let's pay attention to the following points. For example, a cold air flow from under the window is felt. In addition to installing good metal-plastic windows, you can use insulation as a foam sealant. But if this did not help, then the question remains open, how to insulate the room?
Let's try to find other solutions. Fortunately for us, there are several of them. Walls can be insulated with mineral wool, polystyrene foam and polystyrene. Let's consider each option separately.
Thermal insulation with mineral wool
Glass wool is an excellent mineral sealant composed of many fine fibers and produced from glass waste. Glass wool has a number of advantages such as quality, light weight, durability and environmental friendliness. In addition, the cotton wool on the walls is good at reducing noise.
Wadded mats are mounted as follows. First of all, we apply film or primer waterproofing to the wall. Waterproofing is very important 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. The joints between the glass wool mats are sealed with tape, and the rest of the cracks can be blown out with polyurethane foam.
Finally, we apply a second layer of insulation and glue the mounting mesh.
Precautions: do not allow even small particles of glass wool to get into the eyes or into the respiratory system.
It is best to work with this material with glasses, a respirator and cotton gloves.
Insulation with foam
It is possible to use an insulating underlay "Polyform" under the wallpaper, which protects against cold and fungus. And also ultra-thin thermal insulation called "Mascoat".
Thermal insulation "electric warm floor"
The essence of this is to eliminate moisture that accumulates inside the wall. The insulation structure will be slightly different from the first two cases.
In simple terms, this is a wall on which an electric insulation mat is attached. Then comes either cotton wool or foam. And then the finishing itself. The scheme of "warm floor" operation is elementary simple. The insulation heats up the wall, which makes it impossible for moisture to form inside the wall itself. The second big plus is that the electrical insulation 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 electricity costs, in the case of using an electric heater. The rest is a matter of technology.
Foreword... Consider in this article why you should insulate a room in a corner apartment: the reasons for the cold and freezing of the walls in the room. What heaters should be used for work and we will give detailed instructions on how to insulate a room in a corner apartment of an apartment building with our own hands.
The problem of a cold room in an apartment exists among 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 entrance wall, then the question of how to insulate a cold room with our own hands remains 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. At the stage of selection, it is possible to determine a cold room in an apartment or a warm one 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 hallway for a few minutes, and then go into the room and compare the temperature difference, listening to your feelings. If you feel a difference in temperature, then you should be on your guard.
If an apartment in a multi-storey building is on the first or last floor, then the reason for the cold in the entire apartment may be large heat losses through the basement or attic. You can also quite simply figure out this problem yourself - insulate the floor in an apartment on the first floor, and if your living space is on the last floor of the house, then you should insulate the ceiling in the apartment.
In brick houses, poor-quality masonry of the outer walls, which was made by the builders, can become a frequent cause of cold in the room. In panel houses, builders may not properly seal the joints between reinforced concrete panels. There are several simple ways to solve the problem of wall insulation in a corner apartment with your own hands. Let's consider all these methods in more detail below.
Ways of warming a room in a corner apartment
It is believed that external insulation of the facade with foam 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, foam or mineral wool is economically unprofitable 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, ceiling and floor. This method has its drawbacks in the form of rearranging furniture in the room during the renovation, 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 - 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 panel) and can range from 5 to 20 centimeters. In order not to be mistaken in the thickness of the thermal insulation layer, use the calculator for calculating the thickness of the insulation for the walls online on our website. Do not 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 to the level. Next, we lay the insulation, applying glue to each sheet of foam or foam and pressing it against the wall. For reliability, the slabs can be fixed with umbrella dowels. The seams must be staggered and thoroughly foamed if there are gaps.
After installation, a plaster mesh is glued to the insulation, a primer is applied and the entire structure is covered with a facade putty. We considered earlier about the insulation of the facade with polystyrene and how to insulate the house with foam from the outside in more detail. When insulating a corner room in an apartment outside with mineral wool, it is necessary to make a crate.
Mineral wool is placed between the timber rails. The distance between which should be 1-2 centimeters less than the insulation plates 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 the correct side with a vapor barrier 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 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 thermal insulation materials and technical solutions for self-insulation of 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 on two square meters. 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 outside. In addition to installing high-quality metal-plastic windows with double-glazed windows, the window sill should be insulated so that cold air does not blow through it. But besides this, it is necessary to insulate the inside of the wall in the corner room, which is adjacent to the entrance or the outer wall of a brick or panel house.
Warming a room in a corner apartment with mineral wool
Mineral wool is an environmentally friendly insulation consisting of fibers; material is produced from rocks by melting them. The characteristics of mineral wool are good: light weight, low thermal conductivity and sound insulation, long service life. Mats of thermal insulation are mounted on the wall between the rails made of timber or metal profiles for plasterboard.
Mineral wool waterproofing is an important factor, as a damp basalt wool insulation loses its thermal insulation properties. Therefore, before installing the frame, it is necessary to cover the wall with a wind and moisture protection film. It is more convenient to make the frame from wooden slats with a width equal to the thickness of the thermal insulation and the distance between them equal to the width of the insulation mats minus 1-2 cm.
After laying the mineral wool, a vapor barrier or superdiffusion membrane is laid, and slats are packed on the guides to create an air gap. This is necessary so that moisture evaporates from the surface of the superdiffusion membrane. Next, plasterboard, OSB boards or plywood are stuffed onto the slats. It is better to work with mineral wool with glasses, gloves and a respirator.
Warming a room in a corner apartment with polystyrene foam
Foam insulation is more common due to the availability of expanded polystyrene and the ease of its installation. The main characteristics of the foam are lightness, low thermal conductivity and ease of installation. For residential premises, you can buy polystyrene foam, to which substances are added during production that prevent the ignition of 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 trowel, and then the sheet is pressed against the wall. After covering the entire area of the wall, a mounting mesh is glued on top and putty is applied to it. After the putty on the wall has dried, the surface can be painted or covered with vinyl wallpaper.
But when insulating a room in a corner apartment with penoplex, polystyrene or other moisture-proof material, for example, foil foamed 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 closed with a layer of insulation).
How to choose a heater for a room in a corner apartment in a panel house is up to you. It is only important to read the video instructions on this topic and make an accurate calculation of the required thickness of insulation.
