Polyglass, Fernley, Nev., announces ICC approval ER-5954 for its entire line of Polyglass SA self-adhesive membranes. The AC-75 tests confirm not only the physical, chemical and long-term performance of the membranes, but also the strength of its peel and adhesion properties.

"We are the first manufacturer to achieve this rating for self-adhesive membranes," says Jim Akins, technical and warranty service supervisor. Polyglass offers a wide range of SA self adhesive membranes with ADESO technology, which are modified using a "true" APP, SBS or TPO compound on the top weathering layer, and an aggressive self-adhesive compound on the bottom layer.
