UL Environment is proud to offer the Tile Council of North America’s (TCNA’s) Green SquaredSM Certification (ANSI A138.1).
Our dedicated, knowledgeable, and customer service-oriented team members work closely with participating tile manufacturers to ensure a smooth and efficient certification process.
