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.

Grace Construction Products offers a complete line of products and systems that help protect the building envelope from air, vapor and moisture infiltration.

Grace combines innovative technologies and time-tested products to provide reliable waterproofing solutions for virtually all above grade and below grade applications. Grace's high quality membranes and drainage composites are the basis for quality waterproofing systems, helping to protect structures from the damaging effects of water.

Self-adhered window, door and deck flashings from Grace Construction Products provide the highest level of protection against water, air and moisture intrusion. Made of highly adhesive rubberized asphalt compounds, Grace flashings are completely and integrally bonded to high density, cross-laminated polyethylene and have a paper release liner. Our window, door and deck flashings have exceptional adhesion capabilities, can seal around membrane fasteners, and make water-tight laps, ensuring superior performance and long-lasting protection.

DensGlass® Sheathing disrupted the way commercial buildings are designed over 30 years ago, and now DensElement® Barrier System continues that legacy of innovation by integrating 3 products in one: gypsum sheathing, water-resistive barrier and air barrier. AquaKor™ Technology creates the WRB-AB within by integrating the fiberglass mat and gypsum core to form a monolithic, hydrophobic surface that blocks bulk water but allows vapor to pass through, eliminating the need for a separate WRB-AB.

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.

Paraseal is a waterproofing membrane designed for use on structures above and below grade. It is excellent for use on split slab parking, plaza decks, poured and block foundation walls and earth covered roofs. It has outstanding performance when used under conditions of high water head and installed prior to the concrete pour such as retaining walls, elevator pits, etc.

Deckseal is used to seal horizontal or vertical surfaces against the penetration of water. It is excellent for use whenever the membrane is to be covered by earth, concrete or pavers. Unsurpassed for all weather installation to irregular or uncured substrates.

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.

Engineered specifically to meet the needs of the commercial construction marketplace, the DuPont™ Tyvek® Fluid Applied WB System delivers the same industry-leading performance you've come to expect from Tyvek® Commercial Wrap -- with the added convenience of fast, pressure rolled or sprayed application.

Backed by our limited warranty, DuPont™ Tyvek® HomeWrap®, DuPont™ Tyvek® StuccoWrap®, DuPont™ Tyvek® DrainWrap and DuPont™ Tyvek® ThermaWrap™ are trusted weather resistant barriers that help you deliver on the promise of comfortable, energy-efficient homes.

DuPont™ Tyvek® commercial air barriers include DuPont™ Tyvek® CommercialWrap®, DuPont™ Tyvek® Fluid Applied WB System, DuPont™ Tyvek® CommercialWrap® D and DuPont™ Tyvek® ThermaWrap™.

Accessories include DuPont™ Residential Sealant, DuPont™ Tyvek® Tape, DuPont™ Tyvek® Wrap Caps, and DuPont™ RainVent™ Batten furring strips.
