DuPont™ StraightFlash™

Protection for Straight Jambs and Heads of Windows and Doors

<br><b>DuPont™ StraightFlash™</b> is an innovative, single-sided, self-adhered flashing solution that bridges the gap between the rough opening and building envelope to protect against water intrusion around heads and jambs of rectangular doors, windows and other gaps. By sealing vulnerable areas around openings, <b>DuPont™ StraightFlash™</b> can help improve the durability and energy efficiency of both homes and commercial structures. <br><br> <b>DuPont™ StraightFlash™ flashing</b> combines a DuPont™ Tyvek® topsheet with a 100% butyl-based adhesive layer, merging the strength, durability and water resistance of Tyvek® material with the convenience and flexibility of a self-adhered flashing. The result: premium door and window flashing protection that helps keeps rain out and integrates seamlessly with other DuPont™ air and water barriers in a complete building envelope system.

High Performance Durability
  • Helps prevents water intrusion by stopping potential water damage – from rot and corrosion to mold – before it starts, resulting in a more durable wall assembly.
  • Preserves the installed R-Value of insulation, making buildings more energy efficient by helping to prevent air and water leakage.
  • Constructed with a tear-resistant, micro-creped DuPont™ Tyvek® top-sheet and specially designed, quick-release, scored release liner.
  • 100% butyl sealant provides excellent adhesion to most common building materials.
  • Forgiving initial tack provides ability to correct installation mistakes.
  • Does not contain asphaltic / bitumen adhesive materials which many window manufacturers prohibit due to adverse material reactions.
  • Meets AAMA 711, Voluntary Specification for Self-Adhered Flashing Used for Installation of Exterior Wall Fenestration Products.
