Single-sided tape for sealing overlaps and making good around penetrations, pipes and windows. Recommended for all Tyvek membranes. Made of Tyvek and acrylic adhesive for durable and long-lasting bonding.

Tyvek® Butyl Tape.

Double-sided butyl-based sealant, used to seal fixing penetrations in a Tyvek membrane, and form a moisture and airtight seal between a Tyvek membrane and most commonly used building materials. Tape is compatible with brickwork, blockwork, masonry, timber, metalwork and most plastic products.

Tyvek® Double Sided Tape.

Double-sided acrylic tape for sealing laps in Tyvek membrane and bonding to smooth surfaces. Excellent adhesion properties under extreme conditions. Strong initial tack.

Tyvek® FlexWrap EZ.

Narrow width, high performance and heavy duty adhesive tape with good flexibility. The pleated Tyvek® base layer allows the tape to be formed around small and complicated penetration details. Developed to provide sealing against water penetration and achieve efficient vapour and air-tightness.

Tyvek® FlexWrap NF.

High performance flexible self-adhesive flashing tape. It provides excellent watertight adhesion to all Tyvek® breather membranes around non-straight penetrations such as dormers, door sills, chimney breasts, pipe penetrations and any custom shapes.
