Masonry veneer is a single, non-structural outer layer of brick or stone attached to a wall or chimney frame for appearance and weather protection. It carries no building load — the framing or the chimney's structural core does that. Veneer is separated from the backing by an air gap, tied back with corrugated metal anchors, and drained through weep holes and flashing. On chimneys, veneer commonly covers a wood-framed chase or a concrete-block core.
