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. 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. 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.
