| Abstract: |
Two gypsum wall assemblies were exposed to intense real-scale compartment fires, from the time of ignition to beyond flashover. The construction of each assembly (2.44 m by 2.44 m) was identical, with the exception that one of the wall assemblies was insulated with mineral fiber insulation fitted within the stud cavity while the other assembly was not insulated. The assemblies were constructed using type X gypsum panels. For each wall assembly exposed to fire, temperatures were measured at the exposed face, within the stud cavity, and at the unexposed face during the fire exposure. Total heat flux gauges were used to measure the temporal variation of the energy incident on the walls and cameras, both visual and infrared, were used to image the unexposed face of each wall assembly during the fire exposure. The behavior of these two wall assemblies under the fire load is discussed. |
