Square Foot

Square Foot is a premium cored unit that covers a full square foot of wall face economically, making it a low-cost alternative for some commercial applications. Its trapezoidal shape and top-pinning system allow for variable bond construction, accurate alignment, tighter vertical joints and easy installation. Square Foot’s unique design enables a near-vertical setback, and its thick face affords greater durability than other cored systems.
