Dupont Flexwrap NF

The Dupont Tyvek FlexWrap NF is a self-adhering flashing that helps adheres to hard-to-seal corners around windows and doors. This flashing does not require mechanical fasteners and is backed with a 100% butyl-based rubber adhseive layer which makes it a one-step application, saving valuable time and money. It is an extendible flashing material which means it can be stretched and wrapped into rough window openings before the window is installed and has the ability to be applied around other wall penetrations. This flashing also allows for the building to become more energy efficient from prevening air and water leakage from the building. Dupont Tyvek FlexWrap NF is designed to be used with all other DuPont air and water barriers for added protection.
