Thermal insulation of walls

Thermal insulation of walls during construction or reconstruction of buildings is not just important, but necessary.

Heat and energy conservation is one of the most pressing modern tasks. According to regulatory and technical documents, building materials (reinforced concrete, brick, wood) in a single-layer enclosing structure are not capable of providing the required thermal insulation of the building. It can only be achieved in a multi-layer enclosing structure, where an effective thermal insulation material is used as insulation.

Without going into complex calculations, to put it simply, to ensure thermal insulation of a building according to building codes, it is necessary to build walls of brick more than 1 meter thick. It is clear that such a solution is uneconomical and unaesthetic. Therefore, to ensure thermal insulation, insulation materials are used that allow to significantly reduce the thickness of the wall.

Thermal insulation of walls can be done in different ways. There are three insulation options depending on the location of the insulation in the enclosing structure:

• insulation on the inside of the enclosing structure;
• insulation inside the enclosing structure;
• insulation on the outside of the enclosing structure (facade insulation).

Thermal insulation - methods

The option of insulating premises from the inside is not complicated, does not require labor-intensive facade work at a great height. In this case, the thermal insulation material is attached to the wall and covered with plasterboard. Recently, this is how residents of apartment buildings and private houses often "insulate" themselves.

When laying insulation inside the enclosing structure thermal insulation must be made of durable material with a service life no less than the service life of the material from which the wall is made. Another disadvantage of such insulation is the formation of so-called "cold bridges".

The main advantages of facade (external) insulation include ensuring a high level of energy saving (up to 60%) and increasing the sound insulation of external walls.

It is also important to know that improperly performed thermal insulation work can cause the appearance of fungus and mold in the house. Thermal insulation — this means savings on heating, improved microclimate and, ultimately, the longevity of your home.
