When it comes to flashing windows and doors, DuPont™ StraightFlash™ VF is an innovative dual-sided, self-adhered material that provides superior protection against the elements. The unique dual-sided adhesive and specially designed release papers allow this flashing to tie the window or door frame directly to the sheathing or water-resistive barrier to protect from bulk water leaks.

How It Works:
