Barrett Ram 200 is a multi-purpose polyester reinforced, SBS modified bitumen membrane with sanded surfaces. The polymer modification provides exceptional elongation, elastic and cold temperature flexibility properties. The high strength polyester reinforcement gives the composite membrane excellent tensile strength, toughness, puncture and tear resistance that exceeds typical rooftop exposures. Ram 200 can be installed in hot asphalt bitumen or approved cold applied adhesives and mastics.
