Choose Specialised Butyl Tape for Tough Sealing Tasks
DuPont™ Tyvek® Butyl Tape is a butyl based sealant designed specially for use with Tyvek® breather membranes or AirGuard® AVCLs.
This double-sided butyl tape is compatible with most common building materials and helps you achieve airtight and watertight seals that can also withstand humidity and chemicals.
Tyvek® Butyl Tape is most effective when used under compression – for example, under a timber batten. It is recommended for perimeters, chimneys and abutments, and also for sealing nail penetrations and around electrical sockets.
