STROTEX BASIC is a roofing membrane made using economical technology and is recommended for economical structures. It is used on roofs with an open insulation system. With their innovative technology, Strotex membranes equalise differences in water-vapour concentration and so protect the roof's thermal-insulation layer. It protects the thermal insulation from rain and snow from the outside. Thanks to high vapour permeability combined with full waterproofness, the membrane is an excellent wind barrier that protects the thermal insulation in walls and roofs.
