FIREBLOC® Type C gypsum wallboard is the preferred product in the industry due to its consistently high quality standards. Additional properties enhance the core of this type X wallboard to achieve superior performance when used in specific fire rated assemblies. The fire-resistant gypsum core is encased in 100% recycled natural-finish paper on the face side and sturdy liner paper on the back side. The face paper is folded around the long edges to reinforce and protect the core, with the ends being square-cut and finished smooth. Long edges of the panels are tapered, allowing joints to be reinforced and concealed with a joint compound system.
FIREBLOC Type C wallboard is available in 1/2" and 5/8" thicknesses and in a variety of lengths for standard construction uses.
Gypsum wallboard manufactured by American Gypsum contains no asbestos.
FIREBLOC Type C wallboard is used as a covering material for interior walls and ceilings in residential and commercial applications that often require specific fire rated assemblies. It is designed for direct attachment by screws and or nails to wood or metal framing. With joints covered, FIREBLOC Type C gypsum wallboard will resist the passage of smoke.
For additional information on smoke barriers, refer to Gypsum Association publication, “Building and Inspecting Smoke Barriers” (GA-618).
FIREBLOC Type C gypsum wallboard has attained the GREENGUARD Indoor Air Quality Certified status and GREENGUARD Children & Schools Indoor Air Quality Certified status. For more information click here.

Gypsum board does not generate or support the growth of mold when it is properly transported, stored, handled, installed, and maintained. However, mold spores are present everywhere and when conditions are favorable; mold can grow on practically any surface. GYPSUM BOARD MUST BE KEPT DRY to prevent the growth of mold.
Gypsum board must be stored in an area that protects it from adverse weather conditions, condensation, and other forms of moisture. Job site conditions that can expose gypsum board to water or moisture must be avoided.
Gypsum board must be protected during transit with a weather-tight cover in good condition. Plastic shipping bags are intended to provide protection during transit only and must be promptly removed upon arrival of the load. Failure to remove the shipping bag can increase the likelihood of developing conditions favorable to the growth of mold.
Gypsum board that has visible mold growth must not be used. For additional information, refer to Gypsum Association publication, "Guidelines for the Prevention of Mold Growth on Gypsum Wallboard" (GA-238).
Gypsum board must be stored off the ground and under protective cover. Sufficient risers must be used to assure support for the entire length of the wallboard to prevent sagging.
Gypsum board must be delivered to the job site as near to the time it will be used as possible. Individuals delivering gypsum board to jobsites should ensure that it is carried, not dragged, to place of storage/installation to prevent damage to finished edges.
Gypsum board shall always be stacked flat - NEVER on edge or end. Gypsum board stacked on edge or end is unstable and presents a serious hazard should it accidentally topple. Gypsum board should be placed so weight is evenly distributed and the floor is not overloaded.
