High quality 4.0 mm (160 mil) smooth surfaced UL Class A fire-resistant APP Modified Bitumen Roofing Membrane.
Performance Roof Systems' exclusive blend of APP (atactic polypropylene) polymers and select asphalts enhances the weathering capabilities and UV resistance of the membrane.
Dual reinforced with a heat resistant non-woven fiberglass mat followed by a polyester scrim that increases the membrane’s strength and durability.
Top placement of the reinforcement layers allow it to filter out harmful UV rays which reduces natural aging. Therefore the membrane does not require a granule surfacing or a roof coating for protection.
