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

We look forward to extending the same qualities to the roofing industry.”
