Abstract: The structural integrity of steel members is jeopardized when fire insulation is partially lost. This paper examined the thermal and mechanical properties of fire insulation under elevated temperatures to further understand thermal gradients and develop preventative safety measures. A Hot Disk TPS2500 measured the thermal conductivity of the insulation material using the transient plane source (TPS) method. Results show that thermal conductivity increases with temperature because the spray-applied fire resistance materials shrink and become compacted when heated.
