CertainTeed’s Flintlastic line offers an APP modified bitumen roofing system. APP (atactic polypropylene) modified bitumen membranes are self-adhering when heated using a roofing torch. The addition of the atactic polypropylene gives plastic characteristics to the roof and provides enhanced performance to traditional asphalt. When coupled with reinforcements, such as polyester (superior elongation abilities) or fiber glass (high tensile strength), they create high-performance roof membranes with superior performance and longevity. The Flintlastic® APP modified bitumen roofing system uses:
