CalStar Thru-Wall Block Units

CalStar’s Thru-Wall Unit combines the structural properties of standard concrete block with the preferred aesthetic of a traditional brick wall. With nominal sizes of 8 x 4 x 16 and 12 x 4 x 16 inches, the Thru-Wall Unit is half as tall as standard concrete blocks for an authentic brick look and structural use. The dual-sided unit features both a flat face for a classic, 16-inch appearance and a notched face to fill with mortar for the look of 8-inch bricks.
