Of the walls

Without this material, the insulation of loggias or basements, as well as facades of buildings, is rarely done. Today, extruded polystyrene foam is used in the installation of thermal insulation of the walls. And not only external, but also internal. The advantage of the use of this insulation is a significant decrease in heat loss. This material does not allow condensate formation, which eliminates the structure as a whole from the destructive effect of moisture. Among the most demanding grades of polystyrene foams, it is necessary to distinguish two-URSA XPS and PSB-S.
