DACHBAHN, formwork, underlayment, roof covering, Strotex

Underlay membranes are a useful layer in the roof construction, for insulation but also for draining away condensation (sweat). In composition and construction, this film is a multi-layer fleece made of polypropylene. This foil is to be classified as a pre-covering under the cover materials. This film can be attached directly over the thermal insulation, so that rear ventilation is no longer necessary. This Unterspannbhan supports the condensation processes of humid air (water vapor) and storage of the condensed water. The film does not let water through, but moist air. This means that condensed water does not penetrate through the foil but separates on the foil and flows off on the foil surface. This breathable function of the stretch sheet makes it so high quality and is still cheap.

Four-layer roofing membranes have already won millions of customers in United States, now subject Europe. Thanks to the use of the newest technology from the production of roofing membranes, originating in the United States, Foliarex offers you new products of the “EXTREME” class.
