APP Modified Bitumen Roofing Membranes

Johns Manville has developed formulations that enhance the asphalt's overall weatherability by modifying premium-grade asphalts. By combining these modified asphalts with non-woven polyester or glass fiber reinforcements, JM produces waterproofing systems that exhibit tremendous strength, elasticity and weatherability.

APP roofing membranes provide superior tensile strength while maintaining critical flexibility – even in the coldest environments. Additionally, with APP roofing membranes (coated with a proprietary blend of asphalt and atactic polypropylene), contractors now have an efficient mode of application by heat welding, making hot mopping unnecessary.
