The fire resistance requirements are not spelled out as explicitly withinnfpa 101.
Fire wall vs fire barrier vs fire partition.
Ideally firewalls and fire barriers are used together to make a structure as safe as possible.
Typically the main difference is that a fire barrier wall is not structurally self sufficient and does not extend through the roof or necessarily to the underside of the floor above.
Firewalls and fire barriers are both designed to prevent a fire from spreading but these often confused structures are actually quite different.
A fire barrier wall also referred to as a fire partition is a fire rated wall assembly which is not a fire wall.
Some assemblies that resist the spread of fire or smoke are fire barriers horizontal assemblies and fire partitions.
In reference to the term barrier the ibc is very specific that a barrier must have a minimum 1 hour fire resistance rating.
Fire partition both terms get used when referring to fire management systems and passive smoke.
To maximize the benefits of these elements it is important to understand the differences between fire barrier vs fire partition.
For any fire protection plan a fire barrier and fire partition are vital.

Durasystems versatile line of fire barriers can be customized to suit your needs and offer protection options including fire blast ballistics and sound.
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.
Far too often the terms used for fire partitions and fire barriers are interchanged.
However the international building code ibc differentiates the two using the number of fire resistance ratings accorded to each of them.
