Steel Joists, Wood Floor Combustible Concealed?

[bob smith]

I have a light hazard building with Dry wall, 12" bar joists, with 6" of batt insulation on the dry wall and then a wood floor for above. So 6" of dead space above the insulation to the underside of the floor. Would this be considered Combustible Concealed space?
Thanks

Without seeing it or a cross section

I would say yes combustible concealed space, sprinklers required

Because space is not less than six inches

Add another inch of insulation or something.

See what others say

combustible concealed. Add more insulation to avoid sprinklers.

 

[bob smith]

So if they add another 1" of insulation I can get away from the coverage

It needs to be insulation filled. You can get away with, I believe, a 2" air gap AFTER settling, but that is all.

Travis there is the fill option

But if the gap is less than six inches, say five,,, doesn’t that negate sprinklers ?

I believe it is <6" between structural members. I am sure the wording could be cleaned up to truly verify it.
