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?

You should make the side walls with a slight taper this will cut down on the nearfeild reflections.

I read this in Stereophile right after I built my sound room.
bummer!!
