How to insulate the walls from inside the house and apartment – keep the heat indoors In the category Home Insulation Many people are interested in knowledge and learning about many subjects, this knowledge may be vital at some point in your life, attention enough, and dive into more detail more articles and learn more information about How to insulate the walls from inside the house and apartment – keep the heat indoors.

Insulating the walls of the house from the inside is an important aspect in providing a supportive living environment. After all, insulated walls allow you to reduce heat loss in winter and reduce the cost of cooling (conditioning) in summer.

And given the current cost of energy, reducing the cost of home maintenance, the task is very urgent.

Of course, insulating the walls outside will be more correct. And JV 23-101-2004 “Designing thermal protection of buildings” does not recommend this type of work inside the living space.

But, nevertheless, there are cases when internal insulation of walls is the only possible.

insulation of old buildings. It is relevant for residents of houses located in the historical part of the city, where each house is supervised by the Department of Architecture. Despite the fact that during the construction of the building the requirements for insulation of the premises were somewhat different, to warm up from the outside – means to spoil the appearance of the building;

the presence of a deformation seam between buildings. These stitches are tracked by an employee of the State Metrological Service. This procedure allows for metrological monitoring and supervision of the overall condition of the building. Therefore, it is impossible to hide the seam behind the insulation;

The wall is adjacent to the elevator shaft. It is also not possible to warm up on this side either. Therefore, all that remains is the insulation of the walls in the apartment from the inside.

Not only these factors, but also the simplicity of installation work make insulation of the walls inside popular among users.

In this article, we’ll look at how to insulate walls from the inside with your hands and illustrate the highlights with tables, graphs, photos, and videos.

Benefits of internal insulation of the walls of the house

no need for high-altitude work. Especially relevant for residents of multi-storey panel houses. Where the cost of work, often exceeds the cost of materials. And the savings will start to be felt sometime in the third year of operation. Insulating walls with their own hands is also quite difficult, because not everyone has the skills of industrial mountaineering;

the ability to carry out work in any weather. No weather vicissitudes will have a significant impact on the duration of work. Technology will remain the same.

the ability to insulate the interior walls as well as the floor. Named work on the insulation of the floor a priori internal. It is simply impossible to run them from the outside;

the ability to hide communications in the room. For example, heating pipes. Or level the walls in this way. Besides, it’s a good alternative to carpets.

additional soundproofing of the room. This was one of the utilitarian purposes of carpets on the walls – protection from noise from neighbors. Now the role of noise insulation will play insulation;

relatively low cost of work and the ability to perform them with their own hands.

How to insulate the walls from inside the house and apartment - keep the heat indoors

However, the insulation of the walls of the house from the inside has one significant drawback. It cannot be carried out without further repair inside the rooms. Therefore, thinking about internal insulation, it is worth counting how much this event will cost.

It is worth noting the internal insulation of the walls, unlike the outer puts forward certain requirements for insulation material. The main ones are:

Ecology. The insulation, like any other material installed in the house, will contribute to the microclimate of the room. And at the same time it is not always positive. For example, inhalation of harmful formaldehyde, which is abundant in substandard and unnamed cotton wool, carbamide foam or foam, can lead to various diseases in tenants;

compliance with quality standards. Since the internal insulation is always hidden behind a decorative finish, it is often difficult to replace the appearance of defects in the insulation. And different kinds of deformations directly affect the quality of insulation. And it is not always possible to react quickly to the slide, detachment or destruction of the material hidden behind the finish;

low thermal conductivity. The lower this figure, the thinner the layer of insulation material will need to be laid to reduce heat loss. After all, many users are stopped by such aspect as reducing living space due to the use of thick insulation materials. But, it is worth noting that you can get quality insulation not only due to the thickness of the material, how much due to its features and styling technology.

mandatory use of vapor insulation film. This requirement is due to the fact that the vapor inside the building usually goes outside through microfractures in the wall. However, the installation of the insulation, especially soft, is an ideal place for its accumulation. And the wet insulation loses its properties. In addition, over time, because of the wet insulation on the wall formed mold, and the house reigns damp. In particularly neglected cases, the whole design comes into disrepair.
Thus, the price of the insulation and the total cost of work is overshadowed when it comes to insulation of the walls indoors.

In addition to the requirements put forward to insulation, it is important to take into account their compatibility with the material of the wall. After all, for example, the insulation of wooden walls from the inside, especially from a beam or cylindrical log is better to perform with a insulation, which will not hide the natural beauty of wood – harness or pakli. This will be enough, because the tree helps to preserve the heat.

But to insulate brick walls from the inside is simply necessary. Because bricks are most prone to destruction due to environmental factors. And the heat from the room quickly disappears outwards from the micro-cracks appearing every year. The table below shows how many times different types of insulation are more efficient than bricks.

In frame construction, insulation material replaces the wall. Therefore, insulation of the frame walls from the inside is rather a feature of installation technology. But insulation of panel walls from the inside is a good way to save on high-rise work.

Given the variety of modern insulation materials, it should be noted that the technology of insulation of walls from the inside of each of them differs in its features. For a brief review of the main materials and consider the insulation device using the most common of them.

Insulation of walls with foam from the inside

It is not desirable to apply styrofoam inside residential rooms. Although, this material has the lowest thermal conductivity rate of all known. The recommendation is related to the fact that the technology of styrofoam installation is often not maintained. Specifically, the incorrect distribution of glue on the surface of the sheet leads to the fact that there are voids. They accumulate moisture, which will inevitably lead to the appearance of fungus and the destruction of sheets.

Therefore, the glue should be applied with a jagged spatula. Another minus of Styrofoam is its fire insecurity. Styrofoam plates not only burn, but also give off an unpleasant smell during the burning process. At the same time, as evidenced by user reviews, Styrofoam is leading today in the list of the most modern and popular materials for internal insulation. Primarily due to the cheapness of the insulation and the ability to perform the work on insulation with their own hands.

Insulation of the walls from the inside with Styrofoam or insulation of the walls from the inside of the foam. In fact, the same thing, because penoplex is one of the names of extrusion Styrofoam.

In its structure and properties Styrofoam is similar to Styrofoam, so the process of installation they have the same. The sheet is glued to the wall with glue and additionally fixed with a dowel with a large hat (umbrella, fungus). The requirements for the quality of the base are also unchanged – the wall should be dry, smooth and treated with antibacterial solution. The result of the work will be an even wall, ready for further finishing.

Insulation of the walls from the inside of the mine

More complex than styrofoam insulation. This is due to the structure of the material. Vata is a soft and flexible material, so not every type of it can be used as a insulation. As a rule, preference is given to dense mineral plates, rather than rolls.

The mineral cotton wool with the arrangement of the frame is mounted. Placed in the sections of the frame and fastened by the cotton wire will be securely held and will not slide for a long time.

The use of wato requires the mandatory use of vapor insulation. After all, it can perform its functions only being completely dry. The vapor caught in the pores of the vapor displaces the air and accumulates in the form of water. And water is better at heat than dry air. Therefore, the scheme of installation of mineral wool is more like a multi-layered pie. Each, from layers of which, fulfills its mission in ensuring the reduction of heat loss.

Insulation of walls from inside foam

A feature of Separtol is its multi-layered structure. The basis is polyethylene, which is a insulation. It is covered with film with one, and foil, on the other. In fact, it is waterproofing, vapor insulation and insulation in one material. At the same time, its thickness is from 1 to 10 mm. Another plus of Speofol is its composition. It’s an eco-friendly insulation. With its use, the thermos effect is achieved. However, most often spenophine is used together with mineral cotton wool.

Insulation of foam foam (PPU)

Despite the high cost of insulation work, he has his adherents among professionals. This is due to its qualities such as lightness and speed of application, good insulation, eco-friendliness. In addition, senopoliuretan is the only material that does not have mounting seams. This reduces the likelihood of “bridges of cold.”.

Insulation of walls with drywall from the inside

The easiest way to insulate walls. Its undeniable advantage is that the result of the work is a finished wall. In addition, the thickness of the sheet is only 12.5 mm, which together with the use of lightweight profiles for the frame takes no more than three centimeters. But the drywall itself is not a insulation. In this case, the effect will be achieved by the air layer between the wall and the sheet.

Therefore, it is more logical to put in this space mineral cotton wool or any hard insulation. The drawing below shows the sequence of work.

This method of insulation also requires the use of vapor insulation membrane and compliance with the necessary air gaps as in the installation of mineral wato.

Conclusion
Having made a short excursion into the world of insulation materials, and having familiarized yourself with the benefits of internal insulation, you can more confidently choose a suitable way to insulate the walls of the house.
