Where in the IBC? Ask him to provide that reference. There are some restrictions on insulation in concealed spaces but they are specific to the type of insulation, vapor barrier, flame spread, construction Type and Occupancy.
I don't accept a response like that without a Code reference. Craig L.

Sent: Thursday, May 24, 2012 8:30 AM To: Sprinkler Forum ([email protected]) Subject: IBC Question I had an interesting comment from an architect yesterday on a project I am working on. Wood frame building with 12" open web trusses. Due to the floor/ceiling assembly rating, we won't have the minimum 12" to use concealed space sprinklers due to the batt insulation between the floors. Accounting for the insulation, we have approximately 9" of clear space. When the manufactures were contacted, they confirmed that this would be outside the listing of the concealed space sprinkler. We suggested to the contractor that he fill the truss space with insulation per NFPA 13. The RFI came back answered "The exception in NFPA for filling the concealed space with insulations ins technically not permitted by IBC and is not practically effective." While I haven't begun to make the point that the sprinkler protection/spray pattern wouldn't be "practically effective" in this situation and violate the listings, is any one aware of the IBC not allowing the elimination of sprinkler protection in a combustible concealed space where the space is filled with insulation?
