1 hour fire rated wall assembly.

Fire resistance ratings are expressed in the number of minutes or hours a structure can withstand a fire simulation test. Sw 106 1 hour shaftwall with deflection track. The ratings relate to fire tests designed to determine how quickly fire can raise the temperature to unacceptable levels. Usg provides resources here for our ul wall assemblies for seamless integration into any construction project.

According to the engineered wood association a one hour rating indicates that a wall constructed in a manner similar to the one tested will contain flames and high temperatures and support its full load for at least one hour after the fire begins.
