I have a small section (~7 feet wide) of makeshift wall - that consists of simply 7 sheets of 5/8" DW - green glued between them, and screwed in directly to the ceiling beam (which hangs down about 6 inches). Basically through the years, I've added onto the wall thinking (incorrectly that it's too small of a space to impact sound proofing much, and that LOT's of mass +lot's of GG would suffice.) - Anyway - I see my mistake and want to create a frame and decouple it and then reinstall the DW+GG

How can I take this down without ruining the pieces?
I have access to the side and tried prying the pieces apart, but due to the glue doing so may break apart the pieces.
I also tried to a jab saw - but way too many pieces to cut through.

any ideas?

Drywall really isn't made to come down. If you can get to the screws you might have a shot but I doubt it.

Whats a little more money?

I don't know how you would saw the screws without breaking the paper. And once you break paper on DW its strength is gone and it would be worthless in general but even more so for a ceiling. I can't imagine any way it works. I would personally leave it. You are still getting good sound treatment; the bass it coming through the screws but unless you are air tight the removal likely isn't going to improve sound as significantly as you imagine. If you are air tight you should drop the $80 in drywall/screws and whatever you need to in GG and redo. I just hate drywalling. As is, its still better than anything I was able to do for sound treatment.

are you sure that wall is the problem or is sound getting out other ways? Would hate to see you go through the work and see minimal difference.

That's quite a bit of mass.

7 layers THICK? You wouldn't be able to get them down in one shot if you could get to the screws! eek.gif

if you want to take it down you will need to approach it like breaking a boulder into gravel. A whole lot of banging to pulverize it.

Oh wow. I wasn't reading it this way. But now I kinda think thats what he meant. WOW. I wouldn't take that down if my life depended on it and I would be SHOCKED if that is where the sound leak is coming from.

Just so you know anyone who says Green Glue isn't a glue hasn't tried to take apart two pieces of drywall after it has cured.

I'd puzzle my mind with the thought "how do I decouple it while keeping as much as possible of it?" Can't you cut off the outer rim section by section (sawing drywall.... can envision the dustcloud...) and adding decoulpled mountings until you've gone the full way around it.... and then adding what's needed to cover up?

If you start cutting it down keep in mind that it weighs about 980 lbs, plus screws and glue. so call it a half ton.

Good point. Why not leave it in place and ADD a decoupled wall as well? That half a ton has merits on it's own, even if not decoupled.

thanks - I used a reciprocating saw and with not much effort and some dust (though not too bad) took it down.
I could have left it and added a decoupling, but I also wanted to move this (artificial) wall out to give more room in the HT
thx!
