People who prefer suburban houses for permanent life, are increasingly thinking about effective systems for insulation of walls, gender, all this is due to the fact that the price has increased recently for energy.
One of the options to insulate the walls is a foam. The technology of wall insulation with polystyrene is very simple, and in the price it turns out not expensive. For a person, the foam is completely harmless, another plus this material is completely light, thereby will not create any load for the facade of the structure.
In general, polystyrene is a solid foam of polystyrene, which is obtained as a result of polymerization. Foam very positively tolerates the alkaline environment, does not perceive acids, technical oils. Of course, much also depends on the foam manufacturer. It is proved that approximately at a temperature of + 60 the properties of foam worsen. If we take into account that with the chemical interaction of poor -quality foam with plaster, paint the process is accelerated and the foam turns into dust.
Despite the positive aspects of the material, you can take out the weaknesses, for example, the premises in which the ventilation system poorly works can contribute to the accumulation of moisture between the wall and the foam. And the foam, in turn, has a very low vapor permeability and therefore the walls turn out to be breathing in the house, accordingly, the climate in the room will deteriorate, and over time, a fungus or mold may appear. Thus, it is necessary to do vapor barrier from the side of the room.
What is needed in order to insulate the facade of the house with foam?
To start insulation of the facade of the house, it is necessary to prepare the surface. The walls must be leve as best as possible. After eliminating all the irregularities, the walls are primed, glue is prepared and a measured foam sheet is glued to the wall. Using construction tools, sheets are sewn to the facade of the house one after another. Sheets are recommended to be shifted so that the seams do not form along the entire length of the wall.
