subfloor for raised platform

7312 Views 4 Replies 3 Participants Last post by  kimbhoot
I'm building a raised platform for a seating area in my theater room. I have some 0.48" thick OSB, is that sufficient for the floor or do I need 3/4" OSB for the floor?

I have the floor joists 16" on center. when I walk on this floor, it feels fine but I'm not that big. I will feel comfortable using 3/4".
Thanks for the advise.
Going to have to make sure that clean out is still accessable that in that wall.

Good point. will make sure that's the case.
