Firestone SBS Torch Base

$0.00 / ROLL
Firestone SBS Poly Torch Base is a modified bitumen membrane featuring a blend of SBS (Styrene-Butadiene-Styrene) rubber polymer and high quality asphalt 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 provides strength and stability to the product, yielding a membrane that resists natural forces and other factors on the rooftop. The top surface is covered with a fine particle sand surfacing and the bottom surface is covered with a poly burn-off film to aid in heat welding applications. SBS Poly Torch Base membrane is designed specifically as a base layer for use with Firestone SBS Modified Bitumen Systems, and is ideal for use on both new construction and reroofing projects.
