Green & Sustainable

Enabling green/sustainable projects across the nation.

Safe From Fire

See how James Hardie homes survived the San Diego fires.
HardieWrap™ Seam Tape is designed to seal vertical and horizontal seams and small holes in the weather barrier to prevent air and water infiltration. HardieWrap Seam Tape adheres to most surfaces and continues to perform even in low temperatures. It contains no asphalts, VOCs (volatile organic compounds) or solvents, which can reduce adhesion over time.

Together, HardieWrap™ weather barrier, HardieWrap™ Flashing, HardieWrap™ Flex Flashing and HardieWrap™ Seam Tape work with the cladding to form an important part of a home’s weather protection envelope to prevent water damage, mildew and energy loss.1
