This paper presents the results of a number of full-scale fire resistance tests conducted in accordance with the CAN/ULC-S101 standard on wall and floor systems as part of the collaborative research program on the fire and acoustical performance of lightweight assemblies. Based on the test results, the effects of a number of design parameters on the fire resistance performance of assemblies have been investigated including: attachment of the gypsum board, insulation type, resilient channels, gypsum board thickness, number of gypsum board layers, stud arrangements, type of framing, resilient channel and framing spacing, sub-floor type and structural load. The results have shown that the main factors that affected the performance of stud wall assemblies were the type of insulation, the number of gypsum board layers, and attachment of gypsum board. The paper also describes how the information gathered from this study will be used to benefit practitioners, builders and regulators in choosing suitable assemblies for their designs. This includes, a discussion of the models that have been developed to predict the fire resistance of lightweight assemblies. Finally, the paper provides a brief summary of NRC’s future research in the area of lightweight-framed construction.
