Membranes are characterized by high vapor permeability, so they very well discharge outside moisture escaping from the attic side. Membranes can be laid directly on the insulation, and in addition to the roof membranes, the plants can be sealed at the ridge and eaves - this has a positive effect on the energy balance of the roof, as it protects against the penetration of wind gusts. Membranes of proven manufacturers at an attractive price can be found in our online store.
