Low vapor-permeable roof foil of the initial covering, made of polyethylene, reinforced with a polypropylene mesh. Through the use of micro-perforation, it is possible to remove water vapor from the thermal insulation of the roof. At the same time, it is a barrier to the penetration of pollutants and water from the outside.
