Roof waterproofing membrane USB CLASSIC

rollpolypropylene

USB CLASSIC is a highly breathable, 3 layer, impermeable membrane; the top and bottom layers are made of non-woven polypropylenefabric which protect the middle UV 10 polypropylene film. The three layers are joined and heat sealed together. The UV 10 microporous film, in conjunction with a UV stabilizing treatment of the top non-woven fabric layer (corresponding to approximately 5% of the weight of the fabric) make the USB CLASSIC membrane resistant to UV exposure for the duration of the installation of the roof covering. In this case the technical characteristics of the product are guaranteed for exposures of up to 4 months. The membrane’s grammage (185 g/m²) makes USB CLASSIC the basic product for installing a roof package that meets current regulations and at the same time offers good value for money.
