Cover Boards

DensDeck and DensDeck Prime are non-structural, glass mat-faced roof boards that feature a non-combustible, water-resistant and silicone-treated gypsum core panel. DensDeck boards are an excellent substrate in most reroof applications and may be used with mechanically fastened or fully adhered RubberGard EPDM or UltraPly TPO roofing systems and are compatible with Modified Bitumen and BUR systems in certain assemblies. DensDeck and DensDeck Prime products are available from Firestone in 1/4”, 1/2” and 5/8” thicknesses. DensDeck is a registered trademark of Georgia-Pacific.

FiberTop is suitable for use on almost any type of reroofing project and is a durable wood fiber insulation that serves as a recovery board and provides insulating value in roof assemblies. Firestone FiberTop boards may be used under ballasted, fully adhered or mechanically attached single-ply roofing systems. They are also a suitable substrate for base sheets and Modified Bitumen roofing systems. FiberTop boards are available in 1/2" and 1" thicknesses.
