Warmly creates in any home an atmosphere of comfort andsecurity But often, as soon as the outdoor temperature drops below zero, the walls of our houses disfigure the fungus, mold or wet spots. The reason for this is poor-quality building materials, technical errors made during the construction of the house, poor ventilation, insufficient heating, cracks. It is simpler for owners of private houses, they can independently make heating more powerful and patch up the cracks. They can also insulate the walls of the house from the outside, which is considered the optimal solution to the problem of low temperatures in the room. For residents of high-rise buildings, the only way out is to warm the walls from the inside.
Some experts strongly oppose suchworks But what to do if people simply have no choice. Here you can advise to choose the optimal type of insulation and install it correctly. I would like to note that only the wall insulation from the inside will not solve the problem with heat loss in the room. You also need to warm the floor, the ceiling, for example, the attic, to eliminate the cracks in the windows and in the door loot. This is the only way to achieve tangible results.
The market offers a wide range of insulation,each of which has positive and negative sides. The most common basalt fibers, foam plastic (expanded polystyrene), warm plaster, mineral wool, ceramic paint.
Basalt insulation is non-combustible, the most environmentally friendly, but they are afraid of moisture and are quite expensive.
Warm plaster applied without priorleveling the walls, it has a long service life, it “breathes”, that is, it does not give rise to mold, but it is hygroscopic and has less thermal insulation characteristics compared to other materials.
Минеральная вата – легкий, негорючий материал, having good thermal insulation properties. Its disadvantages are hygroscopic, that is, absorption of moisture and lack of environmental friendliness. In many countries, wall insulation from inside with mineral wool is already prohibited.
Insulating (ceramic) paint is very easyare put, quickly grab, are not hygroscopic, do not reduce the area of the warmed room. Disadvantages in their price and in large expense. Usually on 1 square meter of a wall it is necessary to spend 1 liter of such paint. You can also call it a disadvantage of lower insulation than other materials.
Wall insulation foam inside is oneof the most economical and easiest to install. The foam has excellent thermal insulation properties, does not absorb water, a good sound insulator. Disadvantages in its flammability, fragility (breaks at the slightest mechanical effects), and lack of environmental friendliness. Although in all developed countries, foam plastic is readily used not only in construction, but also in other areas (as packaging material).
Technology performance work using itis simple. First you need to level the surface of the wall and treat it with an anti-fungal agent. Next, a special construction glue is applied to the foam sheet. With its help (imposing more or less) it is possible to level a wall not worse, than gypsum plasterboard. Attach the foam start from the bottom corner. If there are gaps between the sheets, they are sealed with glue or inserted into the desired thickness of the strip of foam. You can use foam. For greater strength of attachment, you can use special nails (fungi), hammering them in the corners of each sheet and in the center. In carrying out wall insulation from the inside with foam plastic, the master must ensure that there are gaps between the wall and the insulation, otherwise condensate will collect there. After installation, the structure is fixed with a reinforcing mesh on which a layer of construction adhesive is applied. From above it is covered with a primer, and then it is finished according to the tastes of the owner.
If the wall insulation from the inside is done correctly, the heating system works well and sufficient ventilation is provided, problems in the form of fungus and condensate, as a rule, do not arise.
