Vapor-permeable PROSOCO R-GUARD® FastFlash Air & Waterproof Barrier System
The number-one cause of leaky windows and doors is the interface between frame and rough opening. Those leaks can’t happen when you seal rough openings with PROSOCO R-GUARD FastFlash products during retrofits or new construction. Waterproof from the moment they’re applied through the life of the building, liquid-applied flashing membrane FastFlash; Joint & Seam Filler and Air Dam keep water out of the building envelope and interior -- light Spring rain to Category 5 hurricane.
