Living up to today’s demands for energy efficiency is about meeting or exceeding modern energy codes. DuPont building envelope solutions are designed to control air flow, eliminate leaks, and provide your building with the resilience to contend with the forces of nature.

Products such as DuPont™ FlexWrap™ EZ and LiquidArmor™ Flashing and Sealant improve the weather resistive barrier in your building, providing air and water holdout.

HardieWrap weather barrier provides a balance of water resistance and breathability, reducing water intrusion while allowing water vapor from inside your home to escape. This keeps the area within your walls dry.

HardieWrap Pro-Flashing is a butyl rubber self-adhesive designed to peel and stick around windows and doors to prevent water and air intrusion. It also self-seals around fasteners.

HardieWrap Flex Flashing is designed to easily stretch and seal around custom shapes — including windows and doorsills — to prevent water and air from entering the building.

HardieWrap Seam Tape is designed to seal vertical and horizontal seams and small holes in the weather barrier to prevent air and water infiltration.

The range of DuPont flashing products are durable, tough, tear-resistant and deliver superior protection from water damage and perform through extreme temperatures (they can even handle prolonged exposure to UV light). DuPont™ FlexWrap™, DuPont™ StraightFlash™, DuPont™ Flashing Tape and DuPont™ Thru–Wall Flashing feature quick-release backing allowing for easy installation. And, the forgiving initial tack enables easily repositioning.
