LESSCO Air Vapor Barrier Box
Air leaks can occur around electrical boxes in exterior walls and ceilings, sometimes carrying water vapor that can condense in the wall and attic cavity, leading to rotting, mold growth and an increased heating and air conditioning load. This LESSCO Air Vapor Barrier Box is designed to attach to a wall or ceiling frame and can contain up to 3 conventional electrical boxes.
