The main advantages of thermal insulation from foam
Advantages of thermal insulation of walls outside:
-The design of the wall itself is insulated, thereby it is prevented by its destruction under the influence of wind moisture and other factors;
-With proper installation of the insulation, the wall is breathing, removal of moisture, which accumulates inside the wall, occurs through the outer plaster layer in the outside;
– with external thermal insulation of the walls, it allows you to level temperature fluctuations inside the wall;
– External thermal insulation protects the walls from the oscillating freezing and thawing the wall. The constant heat resistance of the structure is preserved both in winter and in summer.
– the internal, useful space of the room does not stir.
– The wall insulation system outside increases the sound insulation of the house.
From the above advantages, the main thing can be noted: the vapor permeability of the layers, with internal insulation of the walls, is disturbed, since, in a multi -layer wall structure, it should be increased from the inside out. In the absence of additional ventilation, this will lead to the formation of condensate on a vapor barrier layer. The supporting wall during external insulation will be subject to precipitation, temperature, wind and other adverse factors on it. This will lead to a decrease in the service life of the wall.
