Prevent Premium TP-250-Cap

PrevENt Premium TP-250 Heat Welded Cap Sheet is constructed with a tough non-woven reinforced polyester mat strengthened with select glass fiber strands. During the manufacturing process, expandable graphite is added above the reinforcement to impart excellent exterior fire resistance properties. Class A-rated PrevENt Premium TP-250-Cap is coated with select SBS polymers and premium quality asphalt to a thickness of 4.0 mm (158 mils). Ceramic coated mineral granules are embedded in the surface of the product to provide protection against ultraviolet radiation. A light micro-perforated film is bonded to the underside and conveniently disappears upon heat welding. PrevENt Premium TP-250-Cap can be used as a protective cap for a conventional BUR system or as the top ply in a two-ply TorchflexTM system.
