Does Ceiling Drywall Need To Be Fire Rated?

Ceiling drywall requires fire-rated Type X gypsum board when code mandates an hourly fire-resistance rating. Installations such as ceilings under exit corridors, stair shafts, and fire barrier walls generally need 1-hour or 2-hour ratings. Type X gypsum board contains noncombustible glass fibers that slow heat transfer, allowing the assembly to meet ASTM E119 or UL 263 standards. Without a required fire rating, standard drywall may be used for decorative or non-rated ceilings. In projects seeking a metal ceiling finish, fire-rated aluminum ceiling tile systems provide an alternative, combining noncombustible surfaces and tested assemblies. Always consult local building codes and fire-resistance directory listings to confirm whether the specific ceiling assembly requires Type X drywall or an equivalent fire-resistant aluminum system to maintain occupant safety and compliance.
