Superior Compound Formulation

Setting our modified products apart from conventional asphalt technology, Firestone has developed proprietary elastomeric blends of polymers combined with select grades of refined asphalt for exceptional durability, flexibility, and strength. Its elongation properties and cold-temperature flexibility allow Firestone modified bitumen roofing systems to resist thermal and structural movement even in temperatures below 0 F.

Our APP Premium FR, features a tri-laminate mat which uses a high-tensile fiberglass scrim interwoven between two non-woven polyester mats. Needle-punching mechanically binds the three layers together, eliminating the risk of mat delamination.
