A moisture resistant wall vent for use in an exterior wall of a building includes a louvered front panel substantially in the plane of the wall surface whether the wall has a stucco finish, conventional wall finish or a brick surface. Alternatively, the louvered panel may be recessed from the front edge of the vent coincident with the finish of the exterior wall. Top, bottom, left and right side panels of the vent include laterally extending right angle flanges disposed proximate the rear edges to resist seepage of water along the vent into the wall. To mount the vent in a concrete block wall, a laterally extending T-shaped lintel is attached through slots (for the concrete block wall) disposed in the top panel and a laterally extending plate (if used) is attached through slots disposed in the bottom panel. The slots permit outward and inward repositioning of the vent to accommodate the finish on the concrete block wall and to maintain the front panel essentially in the plane of the exterior surface of the wall. To mount the vent in a brick wall, the right angle flanges are attached to underlying framing and an L-shaped lintel supports the course of bricks overlying the vent. To mount the vent in an insulating concrete form exterior wall, the right angle flanges are attached to a buck lodged in the wall.
