Elevate SBS Premium Poly Base is a Styrene-Butadiene-Styrene modified bitumen membrane that is reinforced with a 265 g/m² (5.43 lb/100 ft²) non-woven polyester mat enhanced with continuous glass fiber yarn in the machine direction. The combination results in a flexible, durable membrane. The addition of SBS rubber optimizes the natural waterproofing characteristics of asphalt and increases system performance by adding elongation, elasticity, and flexibility to the sheet. This proprietary compound provides resistance to thermal and physical forces over a wide range of temperatures.

SBS Premium Poly Base is ideal for both new construction and reroofing applications. SBS Premium Poly Base is designed specifically as a base layer for use with Elevate SBS Modified Bitumen Systems and is an excellent choice when a strong, heavy base is required in the roofing system.
