The issue of increasing the thermal insulation of residential buildings is especially relevant today. There are several ways to solve this problem. First of all, this is the use of modern technologies and materials in the process of building houses and cottages. If it is required to insulate a building of early construction, then the most suitable solution in this case would be to insulate the facades and walls of the building..
This kind of work today is performed by a large number of specialized construction companies, from which you can learn more about the service. The walls of residential buildings can be insulated in two ways — external and internal. External insulation can be carried out by using plaster technology («wet facade»), providing for the creation of a light or heavy system, as well as a ventilated facade or well masonry.
The most common of these is the lightweight plastering system. It is a reinforcing layer of small thickness, attached to the surface through insulation with dowels. For this type of insulation, polystyrene, expanded polystyrene or mineral wool is usually used as a heater..
In contrast to the light, heavy insulation system of facades involves the use of steel reinforcing mesh instead of glass mesh, and the fastening of materials to the wall not with dowels, but with the use of steel anchors. In this regard, the thickness of the insulation layer can reach 50 mm. Sometimes ventilated facade systems are also installed. They got their name due to the presence of an air gap between the insulation layer and the building wall. But such systems have a rather high cost, therefore, not available to everyone..
Compared to it, well laying is the most inexpensive. It includes three layers — load-bearing wall, insulation and decorative and protective layer. Typically, such thermal insulation is made with a height of no more than 15 meters..
Internal insulation of building walls also has several options. It can have the appearance of a «wet facade», that is, polystyrene glued to the wall, reinforced with fiberglass, putty and pasted over with wallpaper. But this method is not very practical, since it often leads to the formation of fungus on the walls..
