Polyglass’ SBS (Styrene-Butadiene-Styrene) modified bitumen membranes use a proprietary formulation consisting of the highest quality asphalt, polymers, and modifiers.

Our hot mop-applied SBS membranes are reinforced with polyester and/or fiberglass mats offering superior flexibility, excellent tensile strength, and dimensional stability. The final product provides a highly durable roofing membrane that is capable of sustaining a variety of environmental conditions over time.

For contractors who prefer traditional application methods with time-tested results, Polyglass hot mop SBS membranes deliver a robust, high-performance solution for low-slope roofing systems. Installed using hot asphalt, these membranes achieve a powerful bond to the substrate and between plies, creating a seamless, fully adhered multi-ply assembly. Polyglass hot mop membranes provide a dependable option for projects requiring proven waterproofing, outstanding durability, and code-compliant performance. With enhanced UV resistance, flexibility in low temperatures, and long-term weatherability, our hot mop SBS systems help build roofs that stand up to the harshest conditions—and the test of time.
