Polyglass Announces Modibond® G FR APP Granulated Cap Sheet

Featuring fire retardant additives for low-slope roofing

Polyglass, a leading manufacturer of modified bitumen roofing and waterproofing membranes and roof coatings for low and steep-slope applications, announces Modibond® G FR, an APP (plastomeric) granulated cap sheet for low-slope roofs.

Featuring fire retardant additives, Modibond G FR is specially designed for heat welded applications. It is ideal for new roofing, re-roofing, re-cover, and for flashing details. Modibond G FR can be applied directly over an acceptable substrate or as part of a multi-ply system. It is classified as an acceptable option in UL Class A assemblies for a fully adhered cap sheet on a combustible deck.

Modibond G FR incorporates a high-quality polyester mat, providing superior tear strength and puncture resistance. The quality APP compound and durable construction ensures long-term weathering performance. The top surface is granulated while the bottom surface has a factory applied burn-off film.

With a proprietary blend of APP modified bitumen that allows for superior weathering, Modibond G FR is designed to withstand severe exposure to fire and fortify against increasingly destructive wildfire seasons. In addition to meeting UL Class A assembly standards, Modibond G FR meets ASTM D6222, Type 1, Grade G standards and is FM Approved.
