Greenboard is a paper-faced, moisture-resistant product no longer listed in the International Residential Code (IRC) or International Building Codes (IBC) for use in wet areas. DensGuard tile backer has fiberglass mats rather than paper, which removes a potential food source for mold. Also the core has been engineered to provide a greater moisture resistance than greenboard and in addition there is a moisture barrier on the face to help prevent moisture from entering the wall cavity. Finally DensGuard meets ASTM C1178 which is listed in the IRC and IBC code for use in direct wet areas.
