Thermal insulation of the external walls, ceiling, attic, loggia, saunas and baths will increase the energy -saving effect of the enclosing structures of the building and, accordingly, will reduce the costs of coolants. The foil canvas is used as a reflecting screen behind the batteries (radiators) of the central heating or individual heating panels. In construction, this environmentally friendly rolled material is used as a substrate for the floors, for example, laminate. This is due to the characteristics of foamed polyethylene — elasticity, persistent depreciation properties, microbiological and chemical resistance, resistance to shock effects, high degree of noise absorption. Rollic foamed material is effective when laying on the concrete base of floor slabs, parquet and linoleum, as well as in the installation of “warm floors” regardless of the heating technology.
