Our Roof-Fast Base consists of durable, reinforcing mat of non-woven glass fibers that has been coated and permeated to a thickness of approximately 1.6 mm (63 mils).

The back surfacing is a silicone treated film, which is easily removed. The back surface of the sheet is self-adhesive modified bitumen, which is protected by a silicone treated film. During installation, the silicone sheet is easily removed and the base sheet adheres to the roof deck.
