A smoke barrier is an assembly that is intended to restrict the movement of smoke but also has a one hour fire resistance rating. the biggest difference between a smoke barrier and a one hour fire barrier is a smoke barrier only requires a 20 minute rated opening protection assembly (i.e., fire door shutter), whereas a one hour fire barrier. For example when looking at the above table, a fire wall separating a group s 2 occupancy will require a 2 hour fire rated wall. this rating is expressed in hours and it is the period of time in which a fire wall assembly can maintain the ability to withstand a fire while continuing to perform its given structural function as determined by standard test methods as prescribed in the code.
