M-Bloc® IR Type X interior gypsum panels were designed and tested to not only provide exceptional resistance to mold and moisture, but superior resistance to impact penetration, abrasion, abuse and indention when compared to traditional wallboard. This Type X panel consist of an impact, abuse defiant core encased in heavy abrasion, mold and moisture resistant blue face paper and brown back paper manufactured from 100% recycled paper, with a fiberglass mesh fabric embedded into the core adjacent to the back of the panel to provide additional impact and penetration resistance. 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 IR Type X interior gypsum panels are recommended for commercial and institutional construction where greater resistance to impact, abrasion, abuse and indentation are required. These UL classified panels are allowed for use in any fire rated design where American Gypsum’s 5/8” Type X wallboard is approved. Additionally M-Bloc IR Type X panels can be used as a base for the adhesive application of ceramic or plastic tile in limited wet areas, e.g., bathrooms, kitchens, laundry, and utility rooms.
