Tyvek StraightFlash

StraightFlash Flashing For Flanged and Non Flanged Windows

  • The 4" Dupont StraightFlash roll is standard when installing flashing on windows, over the window flange.
  • Dupont StraighFlash VF is double sided for use on non flanged windows. It is adhesive on both sides to create a flange for the window.
  • StraightFlash is often used in commercial applications due to its 270 day uv exposure and thicker butyl adhesive.
