PetroGrip APP Polyester Fiberglass Membrane TDS
APP-modified torch-applied membrane with composite polyester + fiberglass reinforcement — 3 mm and 4 mm plain PE film finish.
PetroGrip APP Polyester with Fiberglass Reinforcement is a plastomeric torch-applied waterproofing membrane. The composite carrier improves handling strength and dimensional control. Both faces are finished with polyethylene film for roll separation and controlled heat activation.
Plain film-faced membrane is not intended as a permanently exposed UV finish — install screed, tiles, gravel, or another specified protective layer before exposure, or specify aluminum/granular surfacing where exposed service is required.
