HPR® Tri-Base Premium

Triple-reinforced, SBS modified base sheet used as the initial underlayment for Garland's high-performance roofing systems or as a base flashing ply for hot- and cold-applied roof systems.

The superior tensile strength of HPR Tri-Base Premium withstands building movement while its elongation properties allow for constant thermal cycling that exists in every building. Its advanced rubber technology provides increased thermal shock resistance, UV protection, heat resistance, elongation, and low-temperature flexibility.
