Valley Forge, Pa. – June 9, 2009 – CertainTeed Gypsum is pleased to announce its ProRoc Moisture and Mold Resistant Gypsum Board with M2Tech and ProRoc LITE Sand Setting Compounds recently achieved GREENGUARD Indoor Air Quality Certified and GREENGUARD Children & Schools Certification. The company is the first to offer GREENGUARD-certified finishing compound and moisture-resistant gypsum board in both the U.S. and Canada.

“Achieving GREENGUARD certification reaffirms CertainTeed’s commitment to manufacturing sustainable building products throughout North America,” says Doug Gehring, director of marketing technical services for CertainTeed Gypsum. “Building professionals can be confident that the materials available through CertainTeed Gypsum meet the stringent indoor air quality certifications for both residential and commercial projects.”

Facilitated by the GREENGUARD Environmental Institute, both certification programs require products to meet stringent standards in regards to chemical and particle emissions, which can compromise healthy indoor air quality. GREENGUARD standards are based on the U.S. Environmental Protection Agency’s purchasing standards, the State of Washington’s Indoor Air Quality Program, Germany’s Blue Angel Program and the American Society of Heating, Refrigerating and Air-Conditioning Engineers.
