PRODUCT DATA SHEET

DUPONT™ TYVEK® FLEXWRAP™ NF

DuPont™ FlexWrap™ NF addresses the issues of flashing vulnerable bottom corners of the sill where water damage is most likely to occur.

An integral component of DuPont Weatherization Systems, DuPont™ FlexWrap™ NF is a conformable, self-adhesive flashing solution for sills and non-straight portions of windows, doors and other wall penetrations.

DuPont™ FlexWrap™ NF is a premium performance, extendable self- adhered flashing material that can be applied over a wide range of building substances, including non-nailable sheathing materials like PS foam board, fiberboard, concrete masonry unit (CMU) and other such materials. Unlike competitive products, DuPont™ FlexWrap™ NF does not require the use of mechanical fasteners in the flexed corner areas.

DuPont™ FlexWrap™ NF also flashes round-top or custom-shaped windows in a seamless manner, eliminating the need to cut and place individual pieces of conventional flashing on an arched opening.

BENEFITSSuperior protection from water damage

• Helps seal the building envelope when used with DuPont Weatherization Systems products

• Meets the AAMA 711-13 material standard at the highest classification levels: Class A (no primer) and Level 3 Thermal Exposure (80°C / 176°F for 7 days)

• Meets and Exceeds ASTM E331 Standard Test Method for Water Penetration of Exterior Windows, Skylights, Doors, and Curtain Walls by Uniform Static Air Pressure Difference: no leakage at 300 Pa (equivalent to 50 mph windload), even after thermal aging (0-120°F)

• Does not contain asphaltic / bitumen adhesive materials which many window manufacturers prohibit due to adverse material reactions, such as black staining, oozing, and deformation over time, particularly with vinyl flanges.

• Can be installed at external temperatures as low as -4°C (25°F) as long as the surface is clean and free from frost and ice

Easy installation

• Packaged in ready-to-use 6", 9" x 75 ft rolls or 9" x 15 ft rolls • Helps to facilitate the creation of airtight and water tight

seals around windows, door sills, chimney breasts, pipe penetrations, and any custom shapes.

Superior durability

• Extendable flashing constructed with a durable, micro-creped DuPont™ Tyvek® top-sheet, a premium butyl adhesive layer, and a specially designed release liner

• Designed to withstand up to 270 days of UV exposure

Excellent adhesion performance

• 100% butyl adhesive performs through extreme temperatures

• Adheres to most common building materials

PRODUCT DATA SHEET

DUPONT™ FLASHING TAPE

DuPont™ Flashing Tape is easy to install with a forgiving initial tack.

DuPont™ Flashing Tape provides a cost-effective way to help protect jambs, heads, corners and deep sills for today’s windows and buildings.

By helping to channel water effectively outside of the home, DuPont™ Flashing Tape helps protect against water damage that can occur when moisture becomes trapped within the wall system. Providing a durable seal at the window-wall interface, DuPont™ Flashing Tape integrates easily with the complete line of DuPont™ Tyvek® Weatherization Systems.

DuPont™ Flashing Tape uses superior performance butyl based adhesive system and a thermally stable polyolefin top-sheet that will not deteriorate or stain after extended exposure to temperature up to 180°F (82°C). It adheres well to most common building materials, including DuPont™ Tyvek® weatherization wraps, while maintaining a forgiving initial tack, thereby allowing for repositioning with its lightweight release liner and at external temperatures as low as 25°F (-4°C). DuPont™ Flashing Tape meets the requirements for the AAMA 711-13 material standard at the highest classification level.
