The term barrier and partition are frequently thrown around to describe passive smoke and fire management systems. However, when it comes to building codes, the IBC is actually quite particular.
In reference to the term “barrier”, the IBC is very specific that a “barrier” must have a minimum 1 hour fire resistance rating. A “partition” has a fire resistance requirement of 1 hour minimum as well.
More often than not, a fire partition is just a commonly referred to phrase in the industry and really has become synonymous with fire barrier. However, when taking control of the fire protection in your building make sure you are very clear as to the fire resistance requirements.
