StressBase® 80/ 120

Fiberglass reinforced, SBS modified bitumen base sheet designed for use as the waterproofing and reinforcement layer of a BUR or a modified bitumen roofing system.

StressBase sheets can be used as an underlayment or as a base flashing ply for hot- and cold-applied roof systems. The superior strength of the dual fiberglass scrim combined with a blend of SBS polymers provides long-term resistance to splits and tears.
