SBS Modified Asphalt roofs consist of 3′ wide sheets of modified bitumen that incorporates a synthetic rubber-based polymer technology which yields exceptional flexibility, even in extremely low temperatures. SBS membranes can be installed with hot asphalt, cold adhesive, or heat welded.
APP Modified Asphalt roofs consist of 3′ wide sheets that feature a thermoplastic bitumen blend with excellent resistance to UV and higher temperatures. APP membranes can be torched down with heat or applied with cold adhesive.
