A fire barrier wall refers to a type of fire rated wall assembly.
However the wall is not self sufficient because it does not extend below the structure or through the roof meaning that fire and smoke can quickly spread through these two areas.
So a 2 hour fire barrier must have a minimum of a 1.
A fire barrier wall or a fire partition is a fire rated wall assembly that provides lower levels of protection than typically provided by a fire wall.
This type of structure is not self sufficient.
In fact it will rarely extend through the roof or the underside of the floor below the structure.
However in general the life safety code does require smoke barriers to have a minimum hourly fire resistance rating while smoke partitions typically do not require any specific fire resistance rating.
The minimum fire protection ratings of the protective openings on fire barriers are required to be 75 of the fire barrier resistant rating.
The fire resistance requirements are not spelled out as explicitly withinnfpa 101.
Fire rated door assemblies are required to have fire rated doors and frames self closing devices and positive latching.
Differences fire walls building separation openings are protected and limited continuous from foundation to through roof and exterior wall to through exterior wall structural stability fire barrier shafts occupancy separation openings are protected and limited continuous from.
This is a type of fire rated wall assembly.
A fire rated barrier that is rated at 2 hours or greater must have fire dampers in any hvac ductwork that penetrates that barrier.
