Full Description
1.1 This specification covers the minimum requirements for the methods of application and finishing of gypsum board, including related items and accessories.
1.2 Details of construction for a specific assembly to achieve the required fire resistance shall be obtained from reports of fire-resistance tests, engineering evaluations, or listings from recognized fire testing laboratories.
1.2.1 Where this specification is more stringent (size or thickness of framing: size and spacing of fasteners) than the fire-rated construction, this specification shall govern.
1.3 Where sound control is required for a gypsum board assembly, details of construction shall be in accordance with reports of acoustical tests of assemblies that have met the required acoustical values.
1.4 Unheated spaces above gypsum board ceilings shall be properly ventilated (see Appendix X2).
