Fire-Resistant Gypsum Board

When a wall or ceiling needs to do more than just look beautiful, glypsum board can be manufacture to feature fire-resistance. By supplementing regular gypsum board's natural fire resistance with glass fibers and other additives, fire-resistant products proudly carry the Underwriter Laboratories' stamp of approval (U.L. file #R6937).

In addition, fire-resistant gypsum board product lines consist of both Type-X panels and improved Type TG-C panels produced in a range of dimensions as well as a number of other product options to provide performance enhancements to suit a range of specialty applications.


  • May be installed over wood or metal framing
  • Available in both 1⁄2" and 5⁄8" fire-resistant cores
  • Fire resistance classified by Underwriters Laboratories according to ASTM E119
  • Available with a minimum of 93% certified recycled content on a dry-weight basis in accordance with ISO 14021 standards


  • For interior use only
  • Avoid exposure to prolonged, extreme temperatures: 125°F (52°C)
  • Avoid exposure to excessive or continuous moisture
  • Provide adequate ventilation when applying texture to this product
  • Should be stored, handled and installed to comply with industry standards GA216 & ASTM C840

Fire Resistance of 5/8" Type X Panels:

This material has been fire tested in accordance with the requirements of ASTM E119 and therefore may provide a fire rating of one or more hours, depending on the system in which it is applied. Because ASTM procedures require that fire tests be conducted on complete building assemblies/systems and not just on the board itself, the ability of any particular 5/8" Type X gypsum board to pass a specific ASTM fire test may well depend on factors other than the fire resistance of the gypsum board being tested.

Low VOC-Emitting Material:

Gypsum board products are third-party certified by Materials Analytical Services, LLC (MAS) to meet the performance standard established for low-emitting materials under the Collaborative for High Performance Schools (CHPS) Program.

Sulfur Emissions Testing:

In emissions level testing for carbon disulfide and carbonyl sulfide conducted by Materials Analytical Services, U.S producted gypsum board was determined to be negative for sulfur off-gassing and is not considered a problematic corrosive drywall type.


Gypsum board should be carried, never dragged, to prevent damaging the finished edges. When storing gypsum boards, store them indoors and protect them from weather and direct sunlight. Boards should be stored lying flat and neatly stacked. Care should be taken to prevent sagging or damage to edges, ends and surfaces.
