NSF International, an independent global organization that writes public health standards and certifies products for food, water and consumer goods, now offers Green Squared Certification for sustainable ceramic tiles, glass tiles and installation materials.
NSF’s Sustainability division is a leading developer of sustainable standards and certification programs for building and furnishing products such as furniture, wallcoverings, and furnishing fabrics, carpets and flooring.
Developed by the Tile Council of North America (TCNA), Green Squared certification provides accurate, third-party verified information on the environmental impacts of certified tile products.
Green Squared certification through NSF Sustainability helps manufacturers and suppliers of tiles and installation materials distinguish their products from competitors, earn preferred vendor status by environmentally-minded consumers and companies, and demonstrate compliance to state and federal purchasing requirements.
The NSF certification process includes a comprehensive documentation review and onsite facility audit to verify conformance to the standard upon which the Green Squared certification program is based -- ANSI A138.1 American National Standard Specifications for Sustainable Ceramic Tiles, Glass Tiles and Tile Installation Materials.
This consensus-based standard requires an evaluation of products in five categories of performance: product characteristics, manufacturing, corporate governance, innovation, and end-of-life.
“Green Squared provides a standard of excellence in sustainability for the entire industry as it covers not just tile products but also the materials required for their installation,” says Bill Griese, TCNA standards development and green initiative manager. “We are pleased that the certification bodies we have participating in Green Squared are leaders in the realm of developing sustainability standards and certification programs for interior furnishing products, and these organizations have the expertise and industry experience necessary to provide high quality certifications under the Green Squared program.”
Tiles covered by the Green Squared program may include mosaic, quarry, pressed floor, glazed wall, porcelain, specialty, cast glass, fused glass, and low-temperature coated glass tiles.
Installation materials may include mortar adhesives, mastic adhesives, reactive resin adhesives, grouts, tile backer units, crack isolation membranes, waterproofing membranes, water containment membranes, and sound reduction membranes.
