CHARLOTTE, N.C.--National Gypsum, one of the largest gypsum board manufacturers in North America, launched DEXcell™, a new family of high-performance roof boards for commercial roofing systems, recently at the 2014 International Roofing Expo in Las Vegas.

"National Gypsum has the expertise and capability to manufacture DEXcell in our national network of plants and we have a proven track record of unrivaled customer service. We look forward to extending the same qualities to the roofing industry."
