National Gypsum’s gypsum board product line and its ProForm ready-mixed joint compounds have earned GREENGUARD Indoor Air Quality Certified status and GREENGUARD Children & SchoolsSM Certification. These are the industry’s most stringent indoor air quality standards.
The GREENGUARD Environmental Institute, an independent, third-party program, has been certifying products for low chemical emissions since 2001.
To earn the certifications, National Gypsum products passed rigorous sample testing and a review of its manufacturing processes. The certifications are important as concern over indoor air quality grows. Research shows indoor air is two to five times more polluted than outside air.
