I remodeling a bathroom. I’ve removed all of the sheetrock from the walls but not the ceiling. This house has almost 20″ of blown in fiberglass insulation in the attic. I’m thinking about just screwing and gluing on another layer of sheetrock to the existing ceiling. I’m a bit leery of using anything less than 1/2″ thick sheetrock even with the construction adhesive – don’t want it to sag. Anyone had any experience with doing this. I can bite the bullet and bag the insulation over this ceiling if I have to – just don’t want to.
Regards,
Joe C

I have done this a few times not wanting to deal with insulation. First I add screws to the old drywall liberally, then the new layer gets glue and 2" screws.
You shouldn't have any problems just make sure you use addhesive and screw into the joists.

use the 1/2 inch, 3/8 inch can be wavy, especially on a clg.
It worked well in my dining room, over plaster and lath.
Only I didn't use glue. Then I got nervous, and just went crazy nuts with the screws. I must have had them 4" apart over the whole ceiling by the time I felt confident. Which is silly.
You could strap the ceiling with 1x3 and then hang new drywall.

You can laminate over the existing sheetrock. First add screws if any rock is sagged. Then use 1 5/8" coarse thread drywall screws into joists. Have 1 5/8" laminating screws on hand. These are different from the prior screws mentioned, they are specifically used to laminate drywall without having to hit a joist. These will assist you in holding a sheet up without hitting a joist. Also they are used at the seam if the seam does not fall over joists. You can glue if you want, not necessary and a pita.
You may not find laminating screws at box stores, any drywall supply house has them.One pound is enough for a bathroom.The thread is very coarse, and hold the sheets well.
