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.   SQUARE FOOT UNIT MEASUREMENTS HEIGHT   8" (203.2 mm)     WIDTH (FACE)   18" (457.2 mm)     WIDTH (REAR)   14" (355.6 mm)     DEPTH   12" (304.8 mm)     FACE AREA   1 sq. ft.
