M-Bloc® Type C gypsum panels were developed as an improved mold and moisture resistant wallboard with additional properties to enhance the core of this type X wallboard to achieve superior performance when used in specific fire rated assemblies. M-Bloc Type C panels are encased in a mold and moisture resistant blue face paper and brown back paper manufactured from 100% recycled paper. At an independent laboratory accredited in accordance with ISO 17025-2005, M-Bloc panels have been tested to the industry’s most rigorous standard achieving the best possible results per ASTM D3273, scoring a perfect 10 thus minimizing the risk of mold and mildew growth.
M-Bloc Type C gypsum panels are used as a covering for walls and ceilings in residential and commercial applications that often require specific fire rated assemblies. M-Bloc Type C gypsum panels can be used throughout a project as well as the adhesive application of ceramic or plastic tile in limited wet areas, e.g., bathrooms, kitchens, laundry, and utility rooms. M-Bloc Type C gypsum panels are also approved for application to exterior soffits and/or sidewalls in protected corridors/breezeways with indirect exposure to the weather.
