Meets the requirements of ASTM D 6163, 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 Reinforcement Mat: Offers excellent dimensional
stability and tensile strength and withstands differential
movement. Because it has no thermal memory less time is
needed to relax the sheet, allowing for ease of installation.
The fiber glass mat also has good lay-flat characteristics,
contributing to better aesthetics.
Polyolefin Burn-Off Film: Promotes ease of heat welding.
Color: Bright white only
