Abstract
A lightweight concrete masonry unit for veneering the face of a building. The veneer block includes a body with planar front, top, bottom, and side surfaces with the top, bottom, and sides perpendicular to the front surface. One or more channels are formed in the rear surface. The depth of the channels are restricted to maintain no less than one inch of remaining wall thickness between the channel bottoms and the opposite front surface. The novel shape and larger minimum wall thickness of the lightweight veneer block enables production on a commercial block machine within the standard cycle time, provides weight and raw material cost savings up to 50%, and allows block heights that are not attainable with conventional hollow core veneer blocks.
