Diffusion foil under the cover
Bilka 200 g foil is a totally waterproof membrane, protects thermal insulation against rain or snow from the outside and it is also an excellent wind barrier. The product can be used for all ventilated or non ventilated roofs, under a variety of roofing materials ensuring vapour permeability and successfully removing water from the surface. Moreover, excellent wind resistance properties make Bilka 200 foil a material also suitable for the walls of steel structure buildings.
The foil is equipped with double-sided adhesive tape to facilitate the bonding in the overlap area while preventing moisture penetration.
