Thru-Wall Flashing

Thru-wall flashing is a waterproofing component installed horizontally through a wall to divert water away from vulnerable areas, such as wall openings or intersections. Positioned to intercept and redirect water, thru wall flashing helps prevent moisture infiltration and protects the structural integrity of masonry constructions by channeling water away from potential points of vulnerability.
