Sandwich two layers of sheetrock an either side of the Celotex. This gives you a high, low, high mass property and serves as very good isolation. It is not as good as using resilient channels, but short of that method of construction it works very well.
1/2" Celotex instead of sheetrock in sound room?
I am about half way through building my sound room, I have finished the first floor and the garage part. I am about to start on the walls of the room itself. I was planning on using 2 layers of sheetrock for sound isolation properties, when someone suggested substituting one layer of "Celotex", a foam type insulation board with an aluminum foil wrap. Since I live in cold clime, it would certainly help with insulation, but will it adequately work with the sheetrock?
