A specially designed dual-sided adhesive allows StraightFlash VF to tie the window or door frame directly to the sheathing or water-resistive barrier to protect against leaks. StraightFlash VF comprises well-known Tyvek housewrap and a 100% butyl-based adhesive layer. The combination seals against moisture to integrate brick mold, and non-integral flanged and non-flanged windows and doors with the building envelope. Backed by a 10-year warranty.
