Hardie™ Weather Barrier (HardieWrap) provides a superior balance of water resistance and breathability, keeping the area within the wall drier. This helps prevent moisture accumulation that may lead to mold and mildew growth, and it reduces energy loss, potentially saving the homeowner money.

Weather Barrier is installed over the sheathing - beneath the exterior siding - to reduce water and air infiltration.

No exterior cladding can prevent 100% of water intrusion. Every home should have an additional line of defense.

Together, Hardie Weather Barrier, Hardie Pro-Flashing, Hardie Flex Fashing and Hardie Seam Tape form an important part of a home's weather protection envelope. When installed properly, these products help prevent water damage, mildew and energy loss.
