Wood trusses are the overhead structure, The roof Deck above is insulated.
There is going to be a suspended ACT ceiling system below. The combustible
interstitial space ranges from 4' to 5' high between roof deck and finished
ceiling. The floor in question is 4900 SF. Sprinklers listed for
interstitial spaces can't be used. The Open web joists members are in
vertical position, 2x6 top and bottom cord with 2x4 braces, vertical and
angled. The 18" tall joists do not have big openings in them. (I have cuts
sheets I can share with you). I would like to think I can treat them as
obstructed construction. That would allow for heads installed 1"-6" below
bottom of joist. Your thoughts would help. Regards, G. Tim Stone G. Tim
