I am a little confused on the fire blocking code requirement, so I wanted to run this one by the experts before I get too much further. I have soffits running down both sides of my new theater room, forming an L at the wall to ceiling corner. My area follows IBC 2006.

www.optasoft.com/applica ··· 17.2.htmFrom my reading of it, Mineral Wool insulation would be enough, and I assume it gets packed just in the joist and stud cavities, but it doesn't specifically state that. Do I need to also pack the soffit itself? I would rather not, as the recessed fixtures I've already ordered for it are non-IC rated. And would my soffits fall under "717.2.2 Concealed wall spaces" with the 10' max horizontal run? If so, do I just need to create a drywall break to split the soffit up? (its 20' 9" long)
