Product description

Roofing membrane with high, even vapor permeability, thanks to which it keeps the roof dry, which translates into a reduction of energy consumption in buildings. Used as a layer of initial covering under roofing, on sloping roofs. Prevents rainfall from getting into the thermal insulation and roof structure, and also protects against condensation that forms under the base covers. It is characterized by high flexibility and water resistance. It is placed directly above the thermal insulation, without leaving a ventilation gap. Made by electrostatic spot lamination.
