Charlotte, N.C.-based National Gypsum announced in January that its complete line of XP interior gypsum products has achieved Greenguard Indoor Air Quality Certified status and Greenguard Children & Schools Certification.

Walls & Ceilings ran a press release in its March eRock newsletter that stated that G-P’s DensArmor and DensArmor Plus brands were the only Greenguard certified gypsum-based products on the market. We regret the oversight on National Gypsum’s behalf.

National Gypsum’s XP products that have received Greenguard and Greenguard Children & Schools Certification include Gold Bond Brand Hi-Abuse XP, Hi-Impact XP and XP Gypsum Board.

“The Greenguard Environmental Institute applauds National Gypsum on its continued commitment to furthering our mission of improving indoor air quality,” said Dr. Marilyn Black, Founder of GEI. “Products such as the XP interior gypsum line are certified … so consumers and members of the building industry alike can be assured that the products which they are buying are healthy for their indoor environments.”

The XP products feature Sporgard, a combination of mold inhibitors offering the most advanced technology to actively combat mold. Sporgard comes from Syngenta, a world leader in mold control.
