Firestone SBS Modified Bitumen Roofing Systems combine exceptional elongation and fatigue resistance properties with the strength of a glass-reinforced polyester mat. Available in white, black and other granule surface colors, Firestone SBS membranes may be installed by heat welding, hot asphalt, cold-applied adhesive or mechanical attachment.

Firestone APP Modified Bitumen Roofing Systems are available in a variety of thicknesses in smooth and granule surfaces. Reinforced with a tough, non-woven polyester mat, Firestone APP membranes deliver superior rooftop performance for both new and reroof applications. Firestone APP membranes may be installed by heat welding or with cold-applied adhesives.

Firestone offers Ply IV (4) M and Ply VI (6) M asphalt impregnated, glass fiber mat reinforced roofing felts that can installed in multiple layers with a flood coat and aggregate or used in combination with Modified Bitumen.

The Ply IV (4) M and Ply VI (6) M felts provide superior durability and ease of application to construct Firestone Built-Up Roofing (BUR) Systems.

The two-ply Firestone Self-Adhered Base System combines Firestone MB Base SA with either an APP or SBS cap sheet torch-applied directly over the base sheet. The system’s specification flexibility allows specifiers to select the cap sheet best suited to job conditions and local installation practices.

During torch application of the cap sheet, the fiberglass-reinforced base sheet serves as an effective work platform and thermal barrier for torch application. The base sheet also achieves complete fusion, assuring that the MB Base SA System works as a redundant monolithic waterproofing layer beneath the cap sheet.

Firestone Solution for Difficult Details Firestone UltraFlash Liquid Flashing is a 2-part urethane liquid rubber flashing and coating that can be easily applied to the most difficult of rooftop details, creating a durable watertight seal. UltraFlash meets the challenges of creating a watertight seal and is suitable for use with both SBS and BUR systems.

Firestone UltraFlash Liquid Flashing is a fast-curing, low-VOC coating that forms a flexible elastomeric layer around vents, pipes, wires and other difficult roof details. It adheres well to many substrates such as metal, concrete and wood, making it ideal for difficult SBS and BUR repair applications.
