AbstractThe National Research Council of Canada (NRCC) has completed a multi year study of the fire resistance and acoustical performance of a range of traditional and innovative wall and floor assemblies. One of the major components that influences the duration that these assemblies are able to resist the impact of fire, is the gypsum board material used to line walls and the floor assembly ceiling. Traditionally, the gypsum board material used in fire-rated assemblies, such as those studied by NRCC, has been designated as Type X gypsum board. Type X gypsum board can provide up to 90 minutes of fire resistance protection for building assemblies. The classification for this material is based on the product meeting or exceeding a fire-resisting threshold established using a standard test method such as ASTM C 36/ 36M - 031.
