CalStar Products is expanding its masonry line with a Thru-Wall unit. Measuring 8″ by 4″ by 16″ and 12″ by 4″ by 16″, the units are half as tall as standard concrete blocks. The dual-sided units feature a flat face for a classic appearance and a notched face to fill with mortar for the look of 8” bricks. Eight solid colors and three through-body colors are available.The Thru-Wall units employ CalStar’s manufacturing technology which incorporates 40% postindustrial recycled content as the binder. The units are not fired in energy-intensive kilns. Units come in stretcher, knockout bond beam, and corner, sash, and splitable units, and comply with ASTM 90. They have the same fire resistance rating as normal weight concrete block. calstarproducts.com; 877.700.9501
