Cultured Stone Siding Cultured Stone From Owens Corning Owens Corning Cultured Stone products originated in 1962 when brothers Garrett and Floyd Brown of Vallejo, California saw the need for a new kind of building material. The entrepreneurial pair of plasterers developed manufactured stone veneer: exact replicas of natural stones used for building, cast in flexible molds and hand colored with iron oxide pigments. Made of lightweight aggregate materials, the veneers were approximately one-quarter the weight of full-thickness stone and could be adhered to most wall surfaces. The Browns' small, regional company began selling to dealers in northern California, but grew quickly as it added new products with broader geographic appeal. Soon Cultured Stone® products were distributed throughout the United States and Canada. Increased sales eventually established Cultured Stone® as the undisputed brand leader and preferred name in the manufactured stone products industry. Today, the trademark CSV® (Cultured Stone® Veneer) stamp still appears on each and every piece of stone to guarantee customers they are getting the original: a proven and preferred brand they can trust and take pride in. The CSV stamp provides not only proof of authenticity, but a sense of security to customers who demand the best.
