For example, a firewall designed to meet National Fire Protection Agency, (NFPA), 221-09 section A.5.7 which indicates an average temperature of 800 °F (425 °C), is not designed to withstand higher temperatures such as would be present in higher challenge fires, and as a result would fail to function for the expected duration of the listed wall rating. In addition, gypsum board has a noncombustible core that contains chemically combined water (in calcium sulfate). The nominal dimension of a CMU is the actual dimensionplus the width of the mortar joint.
