Exterior Gypsum Sheathing is a water-resistant product designed for attachment to exterior side-wall framing as an underlayment for various exterior siding materials such as wood, metal or vinyl siding, masonry veneer, stucco, shingles, etc. The panel is manufactured with a wax-treated, water-resistant core faced with water-repellent paper on both face and back surfaces and long edges.

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.

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.
