DuPont FlexWrap NF 9" Roll is a premium performance, extendable self-adhered flashing material that can be applied over a wide range of building substrates. The "NF" descriptor stands for "No Fasteners" to highlight the fact that no mechanical fasteners are required during installation of this product.
How FlexWrap NF Works: DuPont FlexWrap NF is an extendable self-adhered flashing material that can be applied over a wide range of building substrates, including non-nailable sheathing materials like PS foam board, fiberboard, concrete masonry unit (CMU) and other such materials. FlexWrap NF products are three-layer assemblies consisting of a DuPont Tyvek top-sheet, an adhesive layer, and a release liner. With it's 100% butyl-based self-adhering layer, it can be stretched and wrapped into a rough window opening before the window is installed, or flashed around arched or custom-shaped windows, as well as other wall penetrations.
DuPont qualifies its flashing products according to the AAMA 711-07 Voluntary Specification for Self Adhering Flashing Used for Installation of Exterior Wall Fenestration Products. DuPont FlexWrap NF comes backed by a 10-year limited warranty from DuPont.
