GREENGUARD Certification

Breathe Easy. Our Interior Wallboard Products Are GREENGUARD Certified.

A majority of people's time – about 90% – is spent inside, maybe in an office building, shopping center, or an elementary school. With so much time spent inside a building, indoor air quality becomes a crucial factor, which is why using GREENGUARD certified building materials is essential in reducing airborne pollutants.

American Gypsum Passes The Test

To attain GREENGUARD Indoor Air Quality Certified® status, American Gypsum's wallboard products passed thorough sample testing and reviews of the our 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(sm) status, the panels, including our family of M-Bloc® Mold and Moisture Resistant products, met even more rigorous emissions limits that take into account the added sensitivity of children and adults with compromised immune systems.


GEI was founded in June of 2001 to establish a true third-party product certification program based on proven emissions standards and to provide specifying and procurement professionals with a resource for low-emitting products. The GREENGUARD Certification Program is an industry-independent, third-party testing program for low-emitting products and materials. The first GREENGUARD Certification was awarded in the fall of 2002. In 2005, GEI announced the GREENGUARD Children & Schools standard, which evaluates the sensitive nature of school populations combined with the unique building characteristics found in schools, and presents the most rigorous product emissions criteria to date.  At this date, more than 200 manufacturers across various industries offer GREENGUARD Indoor Air Quality Certified Products.
