View Full Version : Attic / Intersitial Space

Wondering if anyone would happen to know where specifically the IBC defines interstitial space, or if an attic would be considered a specific type of inerstitial space?
Thanks in advance!

A "Intersitial Space" is a "concealed space"
The IBC and NFPA 13 DEFINE "concealed space"

I hardly think wikipedia is a quotable resource from a building code standpoint. (Not that I didn't see this diagram online before my initial post.)
Having read this section, I do not see any specific reference to interstital space requirements. By your inference that an interstital space is a concealed space, could one also conclude that an "attic" qualifies as a concealed space seeing as attics are referenced in this section?

It does not really address a "real" interstitial space like in a VA hospital. The Wiki-picture is pretty accurate for what is done in these type of facilities. It is always a debate whether this is a concealed accessible space, an occupied floor, part of a floor-ceiling assembly, or other concept. The typical questions are whether it needs to be sprinklered and how to protect penetrations.
