Arriscraft’s calcium silicate brick is unique from clay brick; all Arriscraft brick and stone is made using only natural materials, sand and lime, plus color pigments. This distinct product delivers a fine-grained appearance and the durability qualities of quarried stone. Architectural Linear Series Brick (ALSB), as a calcium silicate product, features a distressed finish not possible with regular clay brick. Higher absorption rates and lack of core holes also mean that installers can achieve high production rates and employ deeper tooled joints for an accentuated linear aesthetic. This popular long brick comes pre-blended with lengths up to 23-5/8" and in four designer colors, with custom colors available (minimum order applies).
