Brick veneer is a single layer of brick installed on the exterior of a building as a decorative and protective façade. Unlike structural brick walls, brick veneer is non-load-bearing and is typically anchored to the building’s frame, which carries the structural load. A gap is usually left between the brick veneer and the wall sheathing to allow for ventilation and water drainage, helping prevent moisture issues. This construction method provides the aesthetic appeal of brick while being lighter and more cost-effective than solid brick walls.
