DUPLAS AP is a high quality polymer-rich APP modified bituminous torch-on membrane with a reinforcement core of spun-bond woven polyester mat, used as a capping layer in waterproofing system.

The DUPLAS range belongs to the plastoproof group of membranes produced using a special grade of bitumen modified with Virgin APP polymer. The polymer-rich mixture is used to saturate and coat both sides of the polyester mat to the required thickness of the membranes. 

FEATURES AND BENEFITS
