M-Bloc® Type X gypsum panels were developed as an improved mold and moisture resistant wallboard with a fire resistant core encased in a mold and moisture resistant blue face paper and brown back paper manufactured from 100% recycled paper. Additionally the core has been reinforced with fibers, increasing its strength and providing fire resistance ratings when used in tested assemblies. 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.

Basic Uses

M-Bloc Type X gypsum panels are a lightweight cost efficient wall or ceiling panel for use 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 X gypsum panels are also approved for exterior soffits and/or sidewalls in protected corridors/breezeways with indirect exposure to the weather.

M-Bloc Type X interior gypsum panels have achieved UL Environment’s GREENGUARD GOLD Certification. GREENGUARD Certified products are scientifically proven to meet some of the world’s most rigorous, third-party chemical emissions standards, helping reduce indoor air pollution and the risk of chemical exposure while aiding in the creation of healthier indoor environments.
