By helping to channel water effectively outside the home, DuPont™ Flashing Tape helps protect against water damage that can occur when moisture becomes trapped within the wall system. Providing a durable seal at the window-wall interface, DuPont™ Flashing Tape integrates easily with the complete line of DuPont™ Tyvek® Weatherization Systems products to help completely seal the building envelope.
DuPont™ Flashing Tape contains no asphalt components; instead, it uses a superior performance butyl-based adhesive system and a thermally stable polyolefin top-sheet that will not deteriorate or stain after extended exposure to temperatures up to 180°F (82°C). It adheres well to most common building materials while maintaining a forgiving initial tack, thereby allowing for repositioning of the product during installation. Application of DuPont™ Flashing Tape can be done efficiently with its lightweight release liner and at external temperatures as low as 25°F (-4°C).
DuPont™ Flashing Tape comes in convenient 4" and 6" roll widths with each roll providing 100 linear feet of coverage. For an average-size home containing twenty rectangular windows, three rolls of DuPont™ Flashing Tape would typically be sufficient to properly flash those window openings (assuming average usage of 15 linear feet of DuPont™ Flashing Tape per window). The 4" DuPont™ Flashing Tape is recommended for flashing the jambs and heads of standard integral flange residential windows. The 6" DuPont™ Flashing Tape is recommended for applications needing better coverage on the head of the window (such as flashing onto “rough-side” OSB).
DuPont™ Flashing Tape meets the requirements for the AAMA 711-05 material standard at the highest classification level. Compliance to this standard helps provide innovative flashing solutions to meet your needs across a broad range of building practices.
DuPont™ Flashing Systems offers a 10-Year Limited Warranty, giving you the assurance that DuPont will stand behind its products. For more information on how to obtain the warranty, please contact your local DuPont™ Tyvek® Specialist or call 1-800-44-TYVEK.
