AbstractThe National Building Code of Canada (NBCC) requires that insulated sheet steel walls commonly used on the exterior of commercial and industrial buildings have a fire resistance rating of 1 h or more. In certain situations this requirement may be waived for exterior walls located 1.2 m or further from adjacent structures (NBCC For such walls, the temperatures, T[u], on the unexposed face during a specified time under fire test conditions governs the required spatial separation. A series of ten small- scale fire tests of insulated sheet-steel walls had previously been conducted to study thermal performance. The present report describes the results of two full-scale fire resistance tests designed to verify small-scale test results and determine fire resistance values and spatial separation requirements for insulated sheet-steel walls. The results of a cavity wall test are also reported.
