Ram 307 FR is a superior SBS (Styrene-Butadiene-Styrene) modified bitumen roofing membrane with fire retardant additives, and reinforced with a non-woven polyester reinforcement that provides flexibility and dimensional stability as well as excellent tear and puncture resistance. The proprietary SBS compound offers superb waterproofing and weathering physical properties.
