Meets the requirements of ASTM D 6162, Type I, Grade G
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 and contains fire-retardant additives. The thicker JM SBS coating provides more waterproofing value.
Fiber Glass / Polyester Reinforcement Mat: Provides stability, toughness and puncture resistance to the product and resists moisture absorption. The reinforcement also provides high tensile strength and affords better natural resistance to the other factors which affect roof performance.
Polyolefin Burn-Off Film: Promotes ease of heat welding.
Color: Bright White only
