Meets the requirements of ASTM D 6164, Type II, Grade G
Reflective Roofing Granules: Specifically engineered for high reflectivity, durability and optimal embedment in the SBS modified bitumen sheet.
Elastomeric SBS Rubber and Asphalt Blend: Provides full recovery properties after 100% elongation, and lends elasticity and flexibility to the sheet.
Heavy Duty Polyester Mat Reinforcement: A tough, nonwoven polyester mat provides excellent tensile strength, toughness and puncture resistance, and can accommodate stresses created by typical rooftop expansion and contraction forces.
