JM APP™ Base
JM APP™ Base is an APP modified bitumen sheet. It incorporates the features of a tough JM glass fiber mat that is saturated and coated with a blend of APP (Atactic Polypropylene) polymer and high quality asphalt.
JM APP Base has a construction that is extremely durable. The premium APP asphalt blend is formulated to provide excellent physical properties for ease of installation and long-term roof performance.
The glass fiber mat provides tensile strength and dimensional stability and can accommodate stresses created by typical rooftop expansion and contraction forces.
The top and bottom surfaces of the sheet are lightly sanded enabling the product to be applied in cold adhesive, by heat welding or by mechanical fasteners.
