Sustainably Manufactured Thru-Wall Units
CalStar Products offers a Thru-Wall unit that combines the structural properties of standard concrete block with the preferred aesthetic of a traditional brick wall. Sizes include 8 X 4 X 16 inches, and 12 X 4 X 16 inches. The dual-sided units feature 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. CalStar Products are made with 40% post-industrial recycled material as the binder, avoiding kiln firing required for clay bricks and the use of Portland cement contained in concrete units.
