Polyflex SA P membranes are premium, self-adhered plastomeric roofing products, manufactured using patented Adeso® Dual-Compound Self-Adhesive technology, whereby a "true" APP polymer modified asphalt compound is applied on the top layer and an aggressive self-adhesive compound is applied on the bottom layer. Polyflex SA P membranes are built with a high performance reinforced polyester mat to excellent dimensional stability. Polyflex SA P membranes are finished with granules on the top surface and feature patented FastLap® for granule free roll ends, as well as SealLap®, a factory applied adhesive treatment at the membrane overlap. Each of these patented features provide for greater ease of application, as well as improved product performance.
