What is fire resistant gypsum board?
CertainTeed Type X fire resistant drywall is an interior gypsum board consisting of a solid set, fire resistive, Type X gypsum core enclosed in ivory-colored face paper and a strong liner back paper. CertainTeed Type X board features 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 Type X fire resistant drywall is available in a variety of lengths and widths.
What is CertainTeed type X?
CertainTeed Type X Fire Resistant Dry wall accepts most types of paints, textures and wall covering materials. The surface shall be primed and sealed with a full-bodied latex primer before applying a final decorative material. This will equalize the suction between the joint compounds and the paper surface. For best painting results, all surfaces, including joint compound, should be clean, dust-free and not glossy. If glossy paints are used, a thin skim coat of compound over the entire surface, Level 5 finish, is recommended to reduce highlighting or joint photographing. This method is also recommended for areas of critical sidelighting of natural or artificial light sources. A sealer application under wallpaper or other wall coverings is also recommended so the board surface will not be damaged if the covering is subsequently removed during redecorating. Joint treatment must be thoroughly dry before proceeding with primer-sealer application and final decoration. Applicable Standards and References ASTM C840 GA0216 GA-214 Consult the GA-600 Fire Resistance Design Manual or UL Fire Resistance Directory, Volume 1 for specific information regarding the construction of fire resistance rated assemblies.

o Fire Resistance – Mold/Moisture-Resistant Gypsum Panels are manufactured with a standard gypsum core as well as enhanced fire-resistive Type C and Type X core variations. These fire-resistant product options can be used in any fire-rated assembly where the corresponding UL-classified Type C or Type X gypsum panel is approved to help design structures engineered for improved fire protection, reduced flame spread and less smoke generation compared to traditional drywall. Refer to GA-600 Fire Resistance and Sound Control Design Manual.
What is the minimum STC for a wall?
o Noise Attenuation – Most building codes recommend a minimum standard STC of 45 for wall assemblies between occupied units in multi-tenant structures to provide a comfortable level of noise protection. Interior walls and ceilings constructed according to assemblies documented in GA-600 Gypsum Fire Resistance and Sound Control Design Manual provide an effective mechanism to achieve improved acoustical performance objectives. Mold/Moisture-Resistant Gypsum Board can be used in any assembly where the corresponding UL-classified 1/2” Type C or 5/8” Type X drywall is approved. more
Where to use gypsum panels?
Mold/Moisture Resistant Gypsum Panels are excellent for use in high humidity areas and even where an occasional splash of water is expected. Appropriate areas include powder rooms, adjacent to showers or tubs, behind counter areas/base cabinetry where plumbing fixtures are located, and in laundry rooms, mud rooms, etc.. However, neither the model codes nor the Tile Council of North America’s (TCNA) Handbook allow for the use of these boards behind the tile in the shower or tub area or as a base under the pan or around a swimming pool or sauna. For acceptable materials in wet areas, consult the local code or the TCNA.
