National Gypsum Announces Dismissal of Attempted Class Action Lawsuit

Suit attempted to tie American-made drywall to problems caused by Chinese products.

---

National Gypsum Company, one of the nation's largest manufacturers of gypsum wallboard, today announced that the plaintiff in Yee v. National Gypsum, et al. (pending in the U.S. District Court for the District of Arizona) voluntarily dismissed his putative nationwide class action lawsuit filed against the company in October 2009.

"While we are pleased with the outcome of this case, we are hardly surprised. Throughout this litigation, we have never doubted the quality and safety of our gypsum wallboard and were confident we would be fully exonerated," said Craig Weisbruch, Sr. vice president of Sales & Marketing. "Our wallboard has passed the industry's most rigorous testing and certification processes for indoor air quality and has been used by the U.S. Environmental Protection Agency (EPA) and the U.S. Green Building Council in their buildings."

The putative class action, Yee v. National Gypsum, et al, alleged that the company manufactured defective drywall which emitted high levels of sulfur, damaged property inside homes and caused health symptoms. These problems have typically been associated with defective Chinese drywall, not domestic drywall. National Gypsum vigorously defended itself against the claims and denied all allegations. The plaintiff did not produce any credible scientific evidence that could substantiate his allegations.

"We have not seen any reliable evidence that our gypsum wallboard poses any of the issues associated with defective Chinese drywall," said Weisbruch.

All of the wallboard that National Gypsum manufactures is made in the United States and has attained the highest level of GREENGUARD certification for helping achieve healthy air in homes, schools, hospitals and other public buildings. National Gypsum's wallboard has earned numerous awards for safety and product quality and has been recognized for its environmental benefits by the EPA and contributes credits to numerous projects certified by the U.S. Green Building Council's Leadership in Energy and Environmental Design (LEED) Green Building Rating System.
