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.
