DuPont™ VersaFlange™ (formerly DuPont™ StraightFlash™ VF) is an innovative, self-adhered window and door flashing for non-flanged and brick mold windows and doors. It features specially designed release papers with dual-sided butyl adhesive, scored backing and a forgiving initial tack, enabling quick and easier installation. DuPont™ VersaFlange™ provides a reliable moisture seal to integrate brick mold, non-integral flanged and non-flanged windows and doors with the building envelope. Uniquely designed release papers allow DuPont™ VersaFlange™ to tie the window or door frame directly to the sheathing or water-resistive barrier to protect from bulk water leaks and supply buildings with superior protection against the elements.
DuPont™ VersaFlange™
Made with a top sheet of DuPont™ Tyvek® – one of the most trusted weatherproofing brands on the market today – DuPont™ StraightFlash™ is ideal for helping to protect the heads and jambs of windows and doors. By bridging the interface between the fenestration and the water-resistive barrier, this premium self-adhered flashing material protects these vulnerable areas from potential water damage.
