My previous opinion on the use of 13R in mixed occupancy buildings was based on incorrect information. What I didn't know was that the text of the 2009 IBC (First Printing Feb 2009) 903.3.1.2 was changed by an Errata. I'm a little embarrassed in not knowing this before I posted my "I'm 100% right" opinion on the matter. For those of you who bought the early printing of the 2009 IBC, this change may clear up some of the confusion.
What is true is that contractors bidding 13R in a mixed occupancy building or portion of a mixed occupancy building need to clarify that any required fire separations (floor assemblies, wall assemblies) are provided by others in order for your 13R system to be adequate.
