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.

LeakBarrier Door and Window Tape is ideal for sealing around window and door penetrations, corner boards, wall tie-ins, sheathing panel seams, under masonry and stucco and other detail areas.

LeakBarrier ValleyFlash is designed for use under composition shingles, shake applications, all types of tiles, as well as in metal roofing applications.

Asphalt Organic Base Sheets are manufactured from premium quality organic mat, saturated and coated with high-grade asphalt and lightly coated with a mineral release material.
