TCNA Material Ingredient Guide, the first of its kind by any building product industry, provides information about the material ingredients used industry-wide by North American tile, mortar, and grout manufacturers, provides in-depth health assessments of those materials, and is a resource for manufacturers to use when providing the content and chemical makeup of their products or “material ingredient transparency.”
For additional information on using the Material Ingredient Guide, refer to this report by the Tile Council of North America.
