AbstractThis report presents the temperature measurements from fire resistance tests conducted at the National Fire Laboratory (NFL) on insulated and non-insulated, smallscale, regular gypsum board protected assemblies.. Assemblies studied were 2x2 (two layers of board on each of the exposed and unexposed sides) on wood and on lightweight steel studs. Three types of regular gypsurn board were studied: 7.82 kgIm2 without glassfibre in the gypsum board core, 7.35 kg/& with glass fibre in the gypsum board core and 7.27 kg/m2 without gllass fibre in the gypsum board core. The insulations used were glass, mineral and cellulose (blown dry) fibres. The effect of using different insulations, type of studs, different mass per unit area of gypsum board and the presence of glass fibre in the core of the gypsum board on the fire performance of small-scale wallboard assemblies were addressed. The average temperatures on the unexposed surface, as well as on theinner-surfaces, are presented.
