NSF International, in collaboration with the Glass Association of North America’s (GANA) Flat Glass Manufacturing Division, developed a product category rule (PCR) for flat and float glass.

Flat glass, for purposes of the PCR, includes sheet glass, plate glass, rolled glass and float glass and is used in a wide range of architectural, auto and decorative applications including windshields, curtainwall, doors, windows and glass panels in furniture. The PCR provides both a science-based and internationally recognized method for reporting the environmental impact of glass products and materials throughout their life cycle from cradle to gate, according to NSF International.

“Developing the flat glass PCR with NSF International is an important next step toward a more sustainable future for the glass industry,” says GANA technical director Urmilla Jokhu-Sowell. “This PCR will give glass manufacturers an opportunity to identify and focus on reducing the environmental impacts of their products and operations and to differentiate themselves in the marketplace.”

Tom Bruursema, general manager of NSF International’s Sustainability Division, adds,

“The development of product category rules for flat and float glass helps meet the increasing demand for transparency in environmental claims. Our robust PCR development and EPD validation services are focused on assisting industries in meeting these market demands with science-based and verifiable information.”

The new PCR is recognized by Leadership in Energy and Environmental Design (LEED) v4.
