GLASS-MAT DRYWALL & BACKER BOARD
Unlike paper-faced wallboard, glass mat gypsum and backer board feature a coated fiberglass mat face and a moisture-resistant, fiberglass reinforced gypsum core. This provides enhanced mold and moisture-resistance for use where moisture damage is anticipated. Our selection of glass mat gypsum products has what you need for tiling jobs and work in high-moisture or wet areas, such as pool areas or bathroom remodels.
