Isolating the house walls from the inside: the choice of materials and installation features

Many skeptics believe that isolating a house or apartment from the inside is not the best option. However, in some cases, there is no way to isolate the wall from the outside world. Internal insulation has actually become the only way to provide warmth and comfort to the house and reduce energy consumption.

How to isolate the house from the interior, and what functions of the process should be considered in this case-we try to reveal this topic to the greatest extent.

The air around us contains vapors of different concentrations. Generally, the vapor concentration in residential premises is usually high. This is caused by cooking in the kitchen, using the bathroom, watering flower pots, wet cleaning and other reasons. Newcomb plusportals birdwhistle Excess water is always removed through ventilation ducts and open windows. But in addition, due to the porosity of the material, they penetrate the wall. When passing through the wall, the vapor molecules will inevitably collide with a condition line under which they become liquid-condensed. This line is called. When using internal insulation, the dew point will always be directly behind the installed insulation, that is, on the inner surface of the wall. Once steam enters the wall, it will condense and wet the wall material. The consequences of this situation are regrettable: an area with ideal conditions is formed immediately after the insulation layer, where bacteria, fungi and mold can grow. Therefore, the premises may even pose a danger to life. Based on the above, we have concluded that the main task of internal insulation is to do everything possible to prevent moist air from contacting the dew point. That is, task 1 is to protect the inner surface of the wall from the slightest contact of steam. This can be done very simply.
Like any other construction activity, internal insulation begins with preparation. First, you need to assess the general condition of the wall, whether there are cracks, plaster fragments, and weak points. It is recommended to eliminate all defects found. It is not so much the quality of insulation as it is to improve the performance of the wall. Correcting defects in a timely manner will prevent them from exacerbating the situation in the future. After all, if the cracks spread further and the plaster falls off, then to solve this problem, you will need to remove most of the insulation and do it all over again. This is not only unpleasant, but also expensive, time-consuming and laborious.
The walls must be inspected for mold and mildew before the interior is insulated. Before the problem is completely eliminated, no follow-up work should be done under any circumstances. If fungal lesions are found, we recommend completely removing the plaster from this area-to the bottom of the wall. Then you need to treat the area 2-3 times with special antifungal chemicals. There should be no visible marks on the surface after processing.

A composition containing active substances for destroying mold on wood, stone, cement and other substrates. It can be used to effectively remove spores, yeast and other types of fungi. Because it contains chlorine, it has the characteristics of instantly destroying fungi and mold. It can penetrate well into the porous wall material, so that damage in the structure can be eliminated. When using, it is recommended to ventilate thoroughly and use personal protective equipment for hands and respiratory organs.
This must be done regardless of whether fungal lesions have been found. In the future, this composition will effectively counteract the formation of mold under the insulating layer. You only need to choose a primer with special anti-corrosion properties and long-lasting effects.
Penetrate deep into the structure, strengthen the surface, remove dust and bind small particles. Reduce water absorption and increase strength. Has a long-lasting bactericidal effect, can prevent fungi and mildew.

The composition has a long-term biocidal effect, so it can be used for subsequent thermal insulation. After the primer is completely dry, you can proceed to follow-up work. The insulation installation technology will come directly from the materials used for wall insulation. In particular, it may be an insulating material using expanded polystyrene or mineral wool. Objectively speaking, expanded polystyrene is the most acceptable insulation material for interior wall insulation. At the same time, only one special type of internal insulation material-extruded polystyrene foam should be used. At the same time, the material forms a dense airless structure, which is characterized by improved strength, rigidity and geometric accuracy. In fact, no steam is allowed to pass. Therefore, this insulation is reasonable and suitable for internal insulation. It becomes a natural barrier between the inner wall surface and the humid indoor air. The extruded polystyrene foam is characterized by an ultra-low thermal conductivity of about 0.32-0.34*. It exhibits excellent heat transfer resistance, so it achieves the greatest thermal insulation effect with a small thickness. At the same time, internal insulation reduces the loss of useful volume.
This material has an excellent cost/performance ratio. The thickness and edge type of the extruded polystyrene foam board are different.
See when to separate the veranda of the veranda, which is part of the living space. There is always an important nuance to be considered when choosing internal insulation materials. The foam board with straight edges at the seam creates a small gap, but it is still a gap. It is a natural bridge through which the cold air enters the room and the steam passes under the insulation layer.
We recommend using only plate-shaped edges with a locking joint system for internal insulation. Due to this configuration, the thermal performance of the insulator is improved, and the vapor permeability is minimized.

Since it is not actually a square meter, it is suitable for a small room. Equipped with shaped edges, it has high heat transfer resistance. Has excellent strength and thermal properties. It has the best thickness for insulating medium and large rooms and balconies.

The most effective heat insulation effect can be achieved by installing this material. Equipped with shaped edges, it can be used to isolate open balconies, loggias, and large rooms. There are two ways to install this type of insulating material-in expanded polystyrene or using glue on positioning pins.

After pre-setting the steam shielding layer, install it on the pin. A metalized backing, film or overlapping polyethylene film is installed on the wall. The seams are glued with aluminum tape to prevent steam from entering under the film. Install the pre-cut plate on the wall and fix it with plastic dowel-fungus with plastic nails. The joint between the board and the pin head is glued with aluminum foil. In this case, the moisture barrier cannot be installed, so pay special attention to the joints. You can use dry glue for expanded polystyrene, such as or. Special glue in the form of low expansion foam can also be used in the cylinder. In order to obtain better adhesion, trim the inner surface of the plate to obtain a rough surface.

The adhesive can be evenly applied to the wall or floor along the edges and the center.
There is a combined installation method using glue and pins. But this is reasonable for the external insulation of the room. Internally, the foam will not bear more pressure. Therefore, choosing one of the options is sufficient. The insulator is a three-layer material, composed of an inner layer of polyisocyanurate foam, and both sides of the inner layer are covered with reflective aluminum foil. Rigid structure, ultra-low thermal conductivity and increased strength parameters. Therefore, it has successfully set itself as a heater for internal insulation in any place from the bedroom to the balcony and loggia. A special feature of this insulation material is that due to the effect of the foil, heat is additionally reflected back into the room. Therefore, the thermal conductivity is reduced to an unprecedented 0.19*, and the water absorption rate is only 1% (this is the time of soaking in water for a day). But most importantly, due to the same foil coating, the vapor permeability of the insulator is reduced to zero. Optimal thickness for medium to large rooms, with shaped edges to prevent cold bridges.

It is recommended to isolate the heated balcony and the balcony of a part of the living space. Fir boards do not allow high-quality fixing of insulating materials using traditional bonding methods. In this case, the technology can be used with plastic mushroom pins with plastic nails. The essence of this technology is no different from the fixation of expanded polystyrene described above. After finishing the installation of the last board, glue the seams together. The gap between the floor and the floor can be covered with polyurethane foam. Carry out further sorting. You can use wooden boxes instead of dowels. The beam presses the insulating material against the wall and then covers it with panels, partitions, plasterboard and other materials.

Mineral wool is not the best insulation material for internal insulation. There is only one reason for this-the cylinder is completely skipped by the steam. Therefore, as stated at the beginning of this article, the dew point is transferred from the inner surface of the wall to the insulating material itself. Condensate will accumulate in it, reduce thermal performance, and form mold and mildew. However, while observing all the technical differences, mineral wool can also be used for internal insulation.
Mineral wool should be selected according to criteria such as thickness and sustainability. You can use rolled lint that is cut directly into the required length during installation. Again, this product is produced on board. For the internal thermal insulation layer, the optimal thickness is 51, at which a good thermal insulation layer can be achieved without significant loss of the room's available space.
The manufacturer recommends for internal insulation, including walls.

Modern insulating materials from a well-known manufacturer are characterized by low thermal conductivity (0.38*) and excellent water repellency due to impregnation of fibers with special compositions. In addition, the board also has a special fiber layout, so the sound absorption rate is greatly improved. Therefore, it is recommended that the insulating material be used to insulate the walls, floors, and interiors of houses in noisy areas.

In addition, attention should be paid to various mineral insulation such as basalt wool. The uniqueness of this thermal insulation material is not only its excellent thermal insulation performance and environmental friendliness, but also its high fire safety. Basalt fibers are derived from natural stone. Therefore, this material has excellent flame resistance.

The fire resistance of basalt wool is an important nuance, which must be taken into account when insulating the walls of wooden houses, country houses, and bathrooms. In this case, we especially recommend choosing certified products. Products designed for thermal insulation of houses, apartments and villas. It is characterized by compliance with environmental standards (low resin emissions and safe in residential sites). Due to the spring characteristics of the insulator, this technology can provide simple installation by filling the gaps in the frame. The material is bio-resistant-bacteria and mold will not form, and it is not a good habitat for insects or rodents.
It is recommended that this insulating material be used for internal insulation with walls, floors and attic interiors. The material has a low thermal conductivity (0.40-0.42 *). Due to the special impregnation, it is non-flammable, biologically stable, and can repel water well without accumulating water inside the structure. At the same time, the compressibility of the slab is 31%, which can simplify the process of placing it between logs and qualitatively seal all cracks and gaps. A moisture-proof film must be installed along the walls.

A frame made of wooden rods is installed on top of the moisture barrier. It is not recommended to use metal profiles. When arranging with basalt wool to insulate the interior of objects with higher fire protection requirements, a metal frame should be used. These include wooden structures: bathrooms, saunas, etc.!
The joint between the frame and the moisture barrier is glued with tape, because the positioning pin will form a hole when fixed in the moisture barrier. The lint has been installed in the frame and carefully sealed to avoid any cracks.
Therefore, a double vapor barrier is created between the insulating wall and the room. The connection points and seams of the moisture-proof layer are bonded with aluminum tape. Following this technique and only in the case of arranging a vapor barrier of an insulator, good results of internal insulation can be achieved. In our own name, we just want to add that isolating houses and apartments from the inside is an extreme and mandatory measure. It is recommended to use it only when the insulation cannot be installed from the outside. If there is such an opportunity, then we definitely recommend that you make its implementation a priority. We hope that the prepared publications will help avoid mistakes and carry out internal isolation as effectively as possible. Radiant Barrier Wall Installation - How To Install Inside Walls
