Price on request
Product description
Dachvent 120 is a roofing membrane with high, even vapor permeability, which keeps the roof dry, which translates into reduced 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.
