DuPont™ Tyvek® Window Tape

Product Code: RA6150WTTV

A high performance airtight tape that can be rendered. It seals difficult areas like windows, doors and timber to block connections.


It is suitable for internal or external usage because it has a moisture adaptive carrier that adapts the Sd value based on the humidity of the surrounding which helps to eliminate the risk of moisture being trapped within the building envelope. It is suitable for sealing junctions of windows and doors in brick and block buildings and forms an airtight yet watertight seal.
