Polyglass’ APP (Atactic Polypropylene) modified asphalt roofing membranes for self-adhered applications are developed and constructed to provide long-term weathering performance that resists natural forces and other factors on the rooftop and ease of application.

The self-adhering APP membranes feature ADESO® Technology, which uses a true APP formulation on the top weathering side and an aggressive self-adhered formulation on the bottom side of the reinforcement.

Polyglass’ self-adhered granulated cap sheets also feature FASTLap®, a patented granule-free end lap and SEALLap® ULTRA, a side lap with self-adhesive compound for an instant bond. APP self-adhered cap sheets can be combined with approved Polyglass self-adhered base/interply sheets as part of a warranted multi-ply system.
