Cold Applied APP Modified Bitumen Roofing Membrane SystemsJohns 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 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. APP Modified Bitumen Roofing SystemDibiten JM is the exclusive source for dibiten APP membrane. This heat weld applied modified bitumen membrane is a high performance solution for both commercial and residential applications. Dibiten is currently available in the Pacific region.
