Derbicolor XPS is a 4.5 mm (180 mil) granule-surfaced APP modified bitumen roofing membrane, triple reinforced with a heat resistant non-woven fiberglass mat followed by a fiberglass and polyester scrim. The data sheet lists a roll 33.5 ft long and 39.4 in wide for 100 square feet of net coverage, with custom color options, and states it meets ASTM D6223, Type II, Grade G. It is applied with PERMASTIC Cold Adhesive or heat welded. Data sheets are also published for an XPS-FR version described as UL Class A fire-resistant, and an XPS-FR-CR version with reflective white granules listing an initial Solar Reflectance Index of 85 under ASTM E1980.
