Expert Verdict — Reviewed by the SuperArbor Pro Desk
Flashing every rough opening is where a weather barrier system succeeds or fails, so order Straightflash by the total perimeter of all openings plus a waste allowance. Keep laps shingled with the direction of water flow and verify substrate compatibility before starting. Pair with HomeWrap rolls from the same brand family for a matched system.
Follow the manufacturer's installation and substrate preparation instructions and use fall protection when flashing openings on upper floors.
Add a 9 in. x 125 ft. roll of DuPont Straightflash to complete your Tyvek weather barrier system.
