Fire Resistive Materials: Thermal Barriers between Fires and Structures



Dale P. Bentz


Fire resistive materials (FRMs) serve a critical function in insulating (steel) structures to limit steel temperature rise during a fire exposure. This paper provides an overview of FRMs, focusing on the measurement of their thermophysical properties. After a brief review of the standard fire test conventionally used to evaluate the performance of FRM-protected components and systems, the measurement of thermophysical properties at room and elevated temperatures is considered. Standard test methods available for each property measurement are noted and example results for FRM materials are presented. These property values can provide critical inputs for simulations of the thermal performance of components and systems during standard and real world fires.
