Where Can I Buy Fire Rated Drywall?
Type X fire rated gypsum drywall that is 5/8 -inch (15.9mm) thick and installed on each side of nominal 2-inch x 4-inch (38x89mm) wood studs spaced 16-inch (400mm) o.c. or 3-5/8 inch (610 mm) steel studs spaced 24” o.c. has a minimum fire rating for the assembly of 1 hour, which is a typical requirement for many building codes.
Type C fire rated drywall (sometimes referred to as Improved Type X) is similar in composition to Type X, except that it has more glass fiber reinforcement and other ingredients in the gypsum core that makes its fire resistive properties superior to Type X. Type C gypsum board is available in 1/2-inch (12.7 mm) and 5/8-inch (15.9mm) thicknesses.
Fire rated Type X Shaftliner is 1” (25.4 mm) thick and used in special Shaftwall and Area Separation Firewall assemblies.
