9 in x 125 ft DuPont StraightFlash


DuPont™ StraightFlash™ is a premium self- adhered flashing material that is ideal for helping to protect heads and jambs of windows and doors. By bridging the interface between the fenestration and the water-resistive barrier, DuPont™ StraightFlash™ protects these vulnerable areas that are so often subject to potential water damage.

When used as part of the DuPont Weatherization System, DuPont™ StraightFlash™ also helps contribute towards U.S. Green Building Council LEED® points, LEED® for Homes points, and The National Green Building Standard™, as well as helping to create more sustainable, durable structures. 

  • Superior protection from water damage
  • 100% Butyl sealant provides excellent adhesion to most common building materials
  • Meets the AAMA 711-13 material standard at the highest classification levels: Class A (no primer) and Level 3 Thermal Exposure (80°C / 176°F for 7 days)
  • Meets and Exceeds ASTM E331 Standard Test Method for Water Penetration of Exterior Windows, Skylights, Doors, and Curtain Walls by Uniform Static Air Pressure Difference: no leakage at 300 Pa (equivalent to 50 mph windload), even after thermal aging (0-120°F)
  • Does not contain asphaltic / bitumen adhesive materials which many window manufacturers prohibit due to adverse material reactions, such as black staining, oozing, and deformation over time, particularly with vinyl flanges.
  • Can be installed at external temperatures as low as -4°C (25°F) as long as the surface is clean and free from frost and ice
