By helping to channel water effectively outside of 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. DUPONT flashing tape uses superior performance butyl based adhesive system and a thermally stable polyolefin top-sheet that will not deteriorate or stain after extended exposure to temperature up to 180 deg F. It adheres well to most common building materials, including DUPONT Tyvek weatherization wraps, while maintaining a forgiving initial tack, thereby allowing for repositioning with its lightweight release liner and at external temperatures as low as 25 deg F. DUPONT flashing tape meets the requirements for the AAMA 711-13 material standard at the highest classification level.
