CertainTeed RipRoc™ Type X Drywall Panel is an interior drywall panel consisting of a non-combustible, fire-resistant Type X gypsum core enclosed in 100% recycled face and back paper. RipRoc™ Type X Drywall Panels feature a specially formulated core providing fire resistance ratings when used in tested assemblies. Long edges are slightly tapered, allowing joints to be reinforced and concealed with joint tape and joint compound. CertainTeed RipRoc™ Type X Drywall Panels are available in a variety of lengths. RipRoc™ Type X Drywall Panels are used for interior walls and ceilings in standard residential, commercial or institutional applications. They can be used for new construction or renovations over wood or steel framing. They are typically nailed or screwed to studs spaced 16" (406 mm) or 24" (610 mm) o.c., but can be applied by laminating or with the use of an adhesive.
