National Gypsum® is one of the largest gypsum board producers in the world, recognized in the industry for product quality. National’s Gold Bond® BRAND panels consist of a fire-resistant gypsum core encased in heavy natural-finish, 100% recycled paper on the face and back sides. The face paper is folded around the long edges to reinforce and protect the core, and the ends are square-cut and finished smooth. For speed of installation, GridMarX® guide marks are printed on the paper surface.
National Gypsum’s interior finishing products fall under the ProForm® BRAND, as “ready mix” or “drywall mud”. National’s cement board, marketed under the PermaBase® BRAND, is used primarily as an underlayment for tile walls, floors and countertops.
