Atlas WEBTECH® Glass Reinforced Felt (GRF) is constructed of 100 percent recycled post-consumer and post-industrial fiber. GRF is widely used as facers for polyiso foam board insulation under waterproofing membranes on commercial roofs.
GRF products are chemically modified and bonded, which improves the final product performance of the resultant mat facer.
GRF is offered in a variety of basis weight ranges from 20 - 40 lbs. and color options include Tan and Black.
