The terms barrier and partition have become interchangeable in common language. However the International Building Code (IBC) is actually quite particular when it comes to their official requirements.
When it comes to a fire “barrier”, the IBC is very specific that a “barrier” must have a minimum 1 hour fire resistance rating. Meanwhile, a fire “partition” has a fire resistance requirement of ½ hour minimum in certain occupancies, while a 1 hour rating for all others.
Often, a fire “partition” is just a commonly referred to phrase in the industry and really has become synonymous with fire barrier. However, determining the fire protection needs in your building make sure you are very clear as to the fire resistance requirements.
