Roofing membranes are used as the base coating level beneath the inclined roofing. They prevent the wind from pushing rain and snow through to the thermal insulation and the roof construction. They protect from condensation forming under the base roofing. In addition, owing to their high vapour permeability, they keep the roof dry, which significantly decreases energy consumption.
