(Tile Council of North America)
An organization of manufacturers serving the ceramic tile industry, with overlapping interest in the stone tile industry, particularly in installation. The TCNA publishes the Handbook for Ceramic Tile Installation and serves as the Secretariat for the ANSI accredited A108 and A118 committees. Established in 1945 as the Tile Council of America (TCA), it became the Tile Council of North America (TCNA) in 2003 to reflect its membership expansion to all of North America - Canada, Mexico and the United States.
