The fire rating of the wall assembly is the lower of the two. Step by step instructions on locating rated walls floors beams and columns. Westbrook block is a proud producer of underwriters laboratories ul approved fire rated cmu in both light weight and normal weight densities in 2 3 and 4 hour configurations. The ratings relate to fire tests designed to determine how quickly fire can raise the temperature to unacceptable levels.
