POLYVAP SA P-AL is a top-quality prefabricated SELF-ADHESIVE bitumen membrane produced using ADESO® technology, the new ELASTOMERIC (SBS) compound laminating system developed by Polyglass SpA. POLYVAP SA P-AL is a membrane produced to the standards set by NAT® technology, the production system for the control of polymer matrix ageing in bitumen membranes. POLYVAP SA P-AL has a stabilised polyester nonwoven COMPOSITE carrier laminated with aluminium foil that gives good dimensional stability and excellent water vapour transmission resistance properties.

An ideal vapour barrier, designed for use under thermoplastic thermal insulation such as expanded polyurethane, expanded and extruded polystyrene.
