AbstractTwo fire resistance tests of non-loadbearing exterior sheet steel wall assemblies, conducted in accordance with test method CAN4-S101-M89, are described. The assemblies were sandwich-type sheet steel wall panels with a 152 mm thick, 64 kg/m3 density, mineral wool insulating core. Normal and thermal Z-bar sub-girts were successively used to support the assemblies. The type of sub-girt showed little influence on the fire resistance of the assemblies, the sagging of the insulation being the dominating factor. The fire resistance ratings did not exceed 45 min, with failure occurring by excessive temperature rise on the unexposed surface of the walls.
