SBS Roofing Systems

DynaLastic 250 FR CR

DynaLastic® 250 FR CR is a fire-resistant, polyester-reinforced SBS modified bitumen sheet. It incorporates the features of a tough polyester mat that is saturated and coated with a blend of SBS rubber, high-quality asphalt and fire-retardant additives. The polyester mat provides excellent tensile strength, toughness and puncture resistance, and can accommodate stresses created by typical rooftop expansion and contraction forces. The covering layer of a white, acrylic coating combined with ceramic-coated roofing granules provides durability along with superior resistance to damage from foot traffic, as well as the benefits of a reflective, emissive surface.
