Derbigum XPS FR Modified Smooth Roof Membrane comes with below features:

• High quality 4.0 mm (160 mil) smooth surfaced UL Class A fire-resistant APP Modified Bitumen Roofing Membrane
• Derbigum's exclusive blend of APP (atactic polypropylene) polymers and select asphalts enhances the weathering capabilities and UV resistance of the membrane
• Triple reinforced with a heat resistant non-woven fiberglass mat followed by a fiberglass and 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
• Derbigum XPS-FR may be used as both a roofing and flashing membrane
• Proven 30-year, in-place performance history
• Can be applied with PERMASTIC Cold Adhesive or heat welded
