I am late to the party, but no, I did not sub the celotex for drywall, the wall I built was 1/2" DW, 5/8" Celo, 5/8" Dwall.

Of course the other leaf was just 2 sheets 1/2" Dwall. All worked well for me. I wonder if I should have built the other wall with 1/2" celo, but like I said.......

It is working well, I will really know in two weeks when I start cutting drums again.

Currently I can crank my soffit mtd monitors to about 93db and go into the other room and hear nothing.

Giles - What is your wall construction? Have any pictures?

PLEASE READ MY ANNOUNCEMENT AT TOP OF THE FORUM...

I havn't any pictures, however read steves announcement... I did glue my surfaces together. As I recall reading back in 98 that the screws will transmit sound.

I Use OSI #38 Drywall adhesive. I screwed down the 1st surface and glued the subsequent one(s)

I use screws to mount the drywall till the glue sealed, then I removed the screwes and plugged all the holes with USG Acoustical sealant. (the second set. I use plain ole silicone on the 1st set of walls.

Yeah, I read about the screws several years ago too, then got sucked in by someone who really should know better - shame on BOTH of us...
