My bad - to be clear, I was talking about the space below the double layer
envelope on the bottom chords, as I misread the question. In the so-called
plenum space between top and bottom chords, it's definitely a combustible
concealed space.

I think it is still combustible within the concealed space as the top and
bottom chords are solid wood members... might still be able to omit sprinklers
if one of the scenarios in the installation chapter applies.

I believe that two layers of the Type X make the space between the presumably
non-combustible ceiling and the sheetrock a non-combustible concealed space.

Spaces Not Requiring Sprinkler Protection
There is a one hour floor assembly which consist of 22" Red-S joist (Wood
Chords with Tube Bars) with 2 layers of type x gypsum board on channels below
joist. Could it be considered limited combustible construction inside the bar
joist? Or am I just grasping for straws, and it needs sprinklers.
Thanks For any replies,
George Medina Jr.
