Elevate SBS Glass is a Styrene-Butadiene-Styrene modified bitumen membrane that is reinforced with a 90 g/m² (1.8 lb/100 ft²) fiberglass mat. The addition of SBS rubber optimizes the natural waterproofing characteristics of asphalt and increases system performance. This proprietary compound provides resistance to thermal and physical forces over a wide range of temperatures. SBS Glass is ideal for both new construction and reroofing applications. Low-slope roofs of any size, even those with numerous penetrations, may accommodate a Elevate SBS Glass application.
