Temple-Inland 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.
In emissions level testing for carbon disulfide and carbonyl sulfide conducted by Materials Analytical Services (MAS), Temple-Inland gypsum board was determined to be negative for sulfur off-gassing and is not considered a problematic corrosive drywall type.
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. These factors include the other components used to construct the building system being tested, the manner in which the system is constructed and the inherent variability of ASTM fire tests. See our Fire-Resistant Gypsum Board page for more information.
Gypsum wallboards 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. Placing boards against framing is not recommended.
