J & S Supply is a major distributor of Firestone SBS Cap Modified Bitumen serving New York, NYC, Brooklyn, Queens, Long Island, Westchester, New Jersey, and Connecticut. SBS Cap is a modified bitumen membrane featuring a blend of SBS (Styrene-Butadiene-Styrene) rubber polymer and high quality asphalt. It is available in Black, White and Ultra White  in 10.2 m long rolls providing net coverage of 98 ft².

Firestone SBS Cap Modified Bitumen is reinforced with a 190 g/m² (3.89 lb/100 ft²) strong non-woven polyester mat enhanced with continuous fiber glass yarns. The addition of SBS rubber polymer optimizes the asphalt blend to increase its natural waterproofing properties, adding elongation, elasticity and flexibility to the sheet. The fiberglass reinforced polyester mat provides strength and stability to the product, yielding a membrane that resists natural forces and other factors on the roof-top. SBS Cap Modified Bitumen can be installed in hot asphalt, with cold adhesive, or with LiquiGard™ adhesive. Firestone SBS Systems are ideal for use on both new construction and re-roofing projects.
