Self adhered butyl flashing that helps prevent water intrusion at window and door sills without mechanical fasteners

DuPont™ Tyvek® FlexWrap™ NF is a stretchable and flexible tape made up of 3 components: a crimped DuPont™ Tyvek® FlexWrap™
NF top sheet providing a watertight layer, the butyl mass as an adhesion layer and a paper release liner.

It provides excellent watertight adhesion to all DuPont™ Tyvek® Building Envelope Solutions products around non-straight
penetrations, such as dormers, door sills, chimney breasts, pipe penetrations and any custom shapes.

 

Benefits:
  • Helps to facilitate the creation of airtight and watertight seals around windows, door sills, chimney breasts, pipe penetrations and any custom shapes
  • Easy to install - no need for additional fasteners
  • Designed to ensure continuity, compatibility and integrity with all DuPont™ Tyvek® Building Envelope Solutions products, as well as other non-wovens and laminated membranes at penetrations
