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.
