Featuring 100% recycled, green treated face paper and a moisture-resistant core, this wallboard provides extra protection against mold and mildew compared to traditional paper-faced gypsum wallboard products in high humidity areas such as kitchens, bathrooms, basements and laundry rooms (not for use in wet areas*).
