Tyvek Flashing Tape 9 inch x 75 ft

DuPont™ Tyvek® Flashing Tape – 9 in x 75 ft Self-Adhered Flashing Tape

DuPont™ Tyvek® Flashing Tape is a professional-grade self-adhered flashing tape designed to seal windows, doors, and wall transitions against air and water intrusion. The 9-inch width provides expanded coverage for larger openings and deeper returns while remaining easier to handle than extra-wide flashing formats.

In simple terms: This wider flashing tape gives you more coverage around windows and doors to help keep wind and water out—without needing multiple layers.

Built with a durable facer and a high-performance adhesive, Tyvek® Flashing Tape integrates seamlessly with Tyvek® weather-resistive barriers (WRBs). The 9-inch width helps reduce seams and overlaps compared to narrower tapes, supporting cleaner detailing and more reliable long-term performance.
