Also, IIRC your roof is rolled roofing over plywood, then the visible joists, then sheet rock??!? Do you NOT need maximum isolation to the outside world, or??!? Steve
Soooo, when a Musician dies, do they hear the white noise at the end of the tunnel??!? Hmmmm...
Don't you want to stagger the seams on the panels going up for strength?
I will on the other layers.
What kind of insulation are you using? Is it JM?
Yes 6 3/4"

My only other option would be RC and I am more conserned with LF.
2 layers should be enough, if not i will add a 3rd layer.
Thank you all for your posts, ill keep the pics comeing as i make progress.

Is that staggering you show recommended? Whenever I heard that, I always thought that we were talking about, for example, making one layer lay North/South and the next layer lay East/West. Should the staggering you are suggesting be done in addition to this?
Right. "Staggering" means making a brick wall type pattern with the drywall sheets. "Rotating" means alternating the direction of each layer of sheets. Both done together increase strength and flatness.
I guess that's the problem of having a job like mine where I can spend pretty much all day (and half the night) working on a project like this: I'm so pooped out that I've totally lost my grasp on the English language!
Rotate of course means to turn it 90 degrees. I don't think it's going to make much more work because my rooms are all oddly shaped to there's lots of cutting to do either way.
I noticed you have a drywall lifter. How has that worked out for you? Are you doing all the drywall work yourself?
This inquiring mind wants to know... He'll be doing the same in the not-too-distant future!
I was planning to purchase a Panellift Telpro 138-2, with the intent of selling it on eBay when I'm done with it. I don't want to be on a "rental clock."
They're not cheap... About $700 or so (not counting any of the accessories), around $200 to $300 higher than the competition. However, from what I have learned, pros love the Telpro. (I even asked a drywall contractor while he was gassing up his truck! )
Without the lift this would be impossible as the ceiling is 13 ft. so far I have been able to do all the panels myself, most only lift to 11 ft. so I had to get the extension that will lift to 15ft. I got mine on ebay, with shipping it came to around 300$ However the crank assembly is flimsy and with the extension it adds allot of stress to that crank. I am hoping it will last for one more layer. If you are only lifting to 11ft. it will work fine,
once I get to my walls ill put the 11ft. extension back in and feel much safer. get the "pro model" if you can afford it and I wouldn’t recommend 12ft. sheets with this model.
