Firecheck Type X is a gypsum board enhanced with glass fibers to offer greater strength and fire protection for interior walls and ceilings. The board has a non-combustible gypsum core and paper facings on the front (ivory), back, and long edges. It is available in several edge treatments, and the ivory facing paper will accommodate a variety of decorative treatments after proper surface preparation. Firecheck Type X is designed for use in applications that require direct mechanical attachment to wood or metal framing or as a component of fire-rated assemblies.
