## Overview

DuPont FlexWrap NF is a premium, 9-inch by 75-foot self-adhering flashing roll designed for easy, fast installation without mechanical fasteners. Its extendable and stretchable properties allow it to conform to a wide range of building substrates and complex window shapes, providing superior air and water sealing. This product integrates seamlessly with DuPont air and water barriers to enhance building durability and energy efficiency, protecting vulnerable corners from moisture damage and maintaining insulation performance.

## Description

DuPont FlexWrap NF is a premium performance, extendable self adhered flashing material that can be applied over a wide range of building substrates, including non nailable sheathing materials like PSfoam board, fiberboard, concrete masonry unit (CMU), and other such materials. DuPont FlexWrap NF self adhered flashing does not require mechanical fasteners, even in flexed corner areas around building openings. This allows it to provide easy, one-step insulation for hard-to-seal corners around windows and doors. FlexWrap NF is designed to help protect vulnerable corners against air and water intrusion, as part of a complete DuPont Building Envelope Solution. It’s effective across a range of window and door designs and a wide range of typical wall substrates. FlexWrap NF integrates easily with all DuPont air and water barriers, to help seal the building envelope for improved durability and energy efficiency. Correctly installed, FlexWrap NF can help stop water from getting at the corners of windows and doors. In turn, that can help prevent water damage, such as wood rot and corrosion,as well as mold. Keeping air and water out can also help maintain insulation R-value, for improved energy efficiency. DuPont FlexWrap NF means “no fasteners.” Instead, DuPont FlexWrap NF is a self adhered, extendable flashing backed with a 100 percent butyl based adhesive layer, making one-step installation and protection possible. And because it’s an extendible flashing material, DuPont FlexWrap NF 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. So FlexWrap NF isn’t just an effective flashing to seal out water, it’s also a cost- and time effective material for crews to work with on the job site.

Review: Excellent product. Used for DYI window installation project in Colorado. Installed 7 windows in the dead of winter with no adhesion issues whatsoever. Flex capability was excellent no plastic corner pieces necessary for waterproofing rough in.
Review: Installing new windows. This product is featured in many of the online home construction instructional videos and websites. There is a slight learning curve in applying this product, but with a little patience it's easy. Strongly adheres to underlying material such as studs and house wrap. Appears to form a tight seal around the sill.

## Questions & Answers

**Q: How do you install this product ?**
A: Peel the backing off lay in place and press down using a ‘J roller’. There is a installation video on it by Du Pont here. https://youtu.be/KMxM03OqAkg

**Q: The dimensions on the box displayed in the image say 7" wide by 75' long.  Is it 7" or 9"?**
A: What I have experienced, it starts out at 7", but flexes up to about 9" in width.  You will not get 9" inches at the corners.  The product made my job easier and is worth the money.

**Q: Can this be used for Roof flashing to prevent water leak?**
A: Better to use wider material.  This is meant for window installation.  Try a 36" wide material

**Q: Can the flexwrap on the sill be installed the day after it rains?**
A: It’s best to install when the sill is dry.

Pricey but a lot less than the local lumber yards charge which is about twice the price.
