AbstractThis report presents the temperature measurements of fire resistance tests conducted at the National Fire Laboratory (NFL) on insulated and non-insulated smallscale assemblies. Three gypsum board wall arrangements were evaluated; namely, I xl (one layer on the exposed and unexposed sides), asymmetrical installation 1x2 (one layer on the exposed side and two layers on the unexposed side) and 2x2 (two layers on both the exposed and unexposed sides). Tests were conducted using 15.9 mm and 12.7 rnmthick gypsum board on steel studs and 12.7 mm thick gypsum board on wood studs. The effects of the installation of glass, mineral and cellulose fibre insulation in the wall Cavity; insulation thickness and method of application for cellulose insulation (wet spray or blown dry) on the fire performance of small-scale tests were studied. The average temperatures on the exposed surface, as well as on the inner-surfaces, are presented.
