Last update: 9:57 a.m. EDT April 30, 2009 DALLAS, Apr 30, 2009 (BUSINESS WIRE) -- American Gypsum, a leading gypsum wallboard manufacturer based in Dallas, TX, announced today that its complete line of interior gypsum panel products has achieved the GREENGUARD Indoor Air Quality Certified(R) status and GREENGUARD Children & Schools(SM) Certification.

The GREENGUARD Certification Program(SM) is an industry-independent, third-party program that has been certifying products for low non-toxic emissions since 2001. To attain GREENGUARD Indoor Air Quality Certified status, American Gypsum's wallboard products passed thorough sample testing and review of the manufacturing processes to meet exacting standards set by the GREENGUARD Environmental Institute (GEI) - an internationally renowned leader in indoor air quality - to establish their impact on indoor air pollution. Then to qualify for the GREENGUARD Children & Schools Certification, the panels, including our family of M-Bloc(R) products, met even more rigorous emissions limits that take into account the added sensitivity of children and adults with compromised immune systems. "Design professionals, contractors and consumers can confidently select any American Gypsum interior gypsum panel product knowing it has achieved the industry's most stringent indoor air quality standards," said Bob Ek, Technical Service Manager.
