I'm using it in my theater. 1/2 inch of Temple fiber board sheathing under 1/2 inch drywall. It's the same thing as the Celotex stuff, only the Temple stuff is about $6. The difference in the Temple SoundChoice and exterior sheathing is that the exterior sheathing is coated in an asphalt material. The Temple rep I talked to said it worked better than the regular soundboard stuff. Plus, I can get the sheathing almost everywhere and everyone quit carrying the SoundChoice 18 months ago. Does it work? I dunno, we're still installing it in the theater right now. A builder friend said he uses it now and then and it works great. Is it messy? Definitely! It's hard to cut because it is made of fibers and the fibers get everywhere and float in the air for a little while. The saw works alright because we got a different blade made for this stuff, but using a dremel to cut the boxes is a pain. BTW, using a router for cutting boxes in the drywall is a breeze.
There are no stupid questions, but there are a LOT of inquisitive idiots. Me being one of them at times.My HT Website in progress.
