POLYVAP SA is a top-quality prefabricated double-sided self-adhesive bitumen membrane made using ADESO® technology, the new compound laminating system developed by Polyglass SpA.
POLYVAP SA is made from a special elastomeric (SBS) compound and has an aluminium foil carrier. This carrier gives the product excellent dimensional stability, good mechanical properties, full vapour control and excellent on-site workability.
POLYVAP SA is protected on both sides with a mono-silicone coated polyethylene backing film to be peeled off as the membrane is laid.
The POLYVAP SA membrane is produced to the quality standards set by NAT® technology the innovative manufacturing system for the control of polymer matrix ageing in bituminous membranes.
