Firestone APP 160 Torch & Cool 

Modified Bitumen consist of select asphalt, modified with atactic polypropylene, and strengthened with a fiber glass reinforced nonwoven polyester mat made with 100% recycled PET fibers. The combination results in a flexible and durable material that exceeds the performance requirements of ASTM D 6222 Type I, Grade S, is strong and stable, and is resistant to natural forces and other factors on the rooftop. They are ideal for both new construction and re-roofing applications as a base ply, cap sheet, or as a flashing sheet in single or multi-ply APP applications.
