Prefabricated bituminous membrane
POLYVAP SA is a high quality double-adhesive bituminous membrane made with ADESO® technology, the new compound layering system from Polyglass SpA. POLYVAP SA is made from a special elastomeric (SBS) self-adhesive compound reinforced with an aluminium foil. This reinforcement allows the product an excellent dimensional stability, good mechanical characteristics, a complete vapour barrier and excellent on-site capability. POLYVAP SA has both sides protected by a mono-silicone coated polyethylene film which is removed when the membrane is applied.
