The Ideal Seam Tape for Tyvek® Weather Barriers

Choose the best seam tape for sealing DuPont™ Tyvek® weather barriers against air and water in both residential and commercial construction.

Finish the building envelope with a superior seam tape – DuPont™ Tyvek® Tape. It helps to create a continuous building envelope system which keeps water and air out. Benefits can include not only better building durability but improved energy efficiency through reduced air leakage.

Effective Material Science

Tyvek® Tape is strong, easy to use, and highly waterproof. It is constructed of an oriented polypropylene film, coated with a specially formulated permanent acrylic adhesive to create the best adhesion between seam tape and DuPont™ Tyvek® weather barriers. 

Improved Energy Efficiency

From a single family home to an office tower, air and water infiltration can make insulation significantly less effective, heating and air conditioning more costly. Tyvek® Tape contributes to energy efficiency by helping to seal the building envelope, which controls air flow and water intrusion in the wall assembly. 

How It Works

Using DuPont™ Tyvek® Tape to seal seams in the weather barrier after wrapping is the best practice for achieving maximum benefit of an air and water barrier to protect the building envelope. Our seam tape also features a specially engineered adhesive that offers the outstanding adhesion to DuPont™ Tyvek® weather barriers.
