Effects of Thermal Insulation on Fire Resistive Assemblies
Guidelines are presented for determining the effects of added thermal insulation on the fire resistance of concrete wall and roof assemblies. When the fire resistance of a concrete assembly is governed by temperature rise criteria, adding thermal insulation actually increases the fire resistance. If the fire resistance of the concrete assembly is controlled by structural criteria, adding thermal insulation usually will not change the fire resistance of the assembly. Research has shown that the addition of insulation in some fire-resistive assemblies can adversely affect performance. Evaluation of assemblies with increased levels of thermal insulation should be required by building officials to determine new hourly fire ratings.
