Meets the requirements of ASTM D 6221, Type I, Grade G

DynaFlex CR G  is used as a composite-reinforced cool roof cap sheet membrane in a variety of multi-ply roofing systems.

Reflective Roofing Granules: Specifically engineered for high reflectivity, durability and optimal embedment in the SBS modified bitumen sheet.

High-Quality SBS Rubber and Asphalt Blend: Lends elasticity and flexibility to the sheet. The thicker JM SBS coating provides more waterproofing value.

Fiber Glass/Polyester Reinforcement Mat: The inorganic fiber glass reinforcement, in conjunction with the polyester, provides stability, toughness and puncture resistance to the product, and resists moisture absorption.
