Over the past four years, I have moved away from specifying typical flashing tapes for installation at windows, doors, and penetrations.
Recently I have specified on numerous projects theBEI Wet-Flash system.
- This is a liquid-applied flashing system that, in my opinion, outperforms the typical and more common flashing systems.
- Since this is a liquid-applied flashing system, it eliminates all seams and overlaps, which are the source of most leaks around window openings.
Per the manufacturer literature, the product is 99% solids; it is described as a single-component, elastomeric, liquid-applied coating/sealant, exhibiting the combined benefits of silicone and urethane.
