How would you install drywall to the ceiling???
 
1) Would you use 2 layers (1/2") of sheetrock or 1 (5/8")?
2) Would you add resilient channels (i.e. RC-1) to the joists before installing the drywall? Or would you install 1x3 or 1x4 fir strips perpendicular to the joists?
3) Would you use 1-5/8" or 2" screws or nails? And how close throughout the drywall board?
4) Would you install rockwool/mineral wool insulation to help with sound/noise transmission/reduction?

Thank you in advance!

1 no I would not use 2 layers
2 if your joists are 24"oc just screw 5/8 to the joists
3 1-5/8
4 yes
Now having said that let me ask some questions are there pipes and wiring in this ceiling,including waste pipes. What I'm really trying to say is if there is anything in the ceiling you may have to get to later then drywall is not your best choice. You may want to consider a drop ceiling so you will have access.

3 1-5/8 Screws - I assume - ???
4 yes

Thank you, ToolSeeker.

The ceiling will be drywall and not drop ceiling. This decision was made in terms of "less basement look" - like the rest of the house.

If you have movement in your joists then add some cross bracing to eliminate the movement. And yes screws.

drywall
 
You can also use lite drywall which is (the claim) 30% lighter than regular drywall. It is also stiffer an won't give you the potential sag that regular drywallsometimes produces with 24" centers.

the sheets are lighter and a bit more brittle and rated for 24" centers. before the ultra came out there was 1/2" sag resistant drywall for ceilings. your doing the basement ceiling and most of the time the floor joists are 16" centers and any old 1/2" will do the trick.

Thank you!

I have elected to go with the followings:

1). Ultra lite 1/2 single layer
2). Resilient Channels perpendicular to the joists (24" oc)
3). 1-5/8" fine thread screws
4). Roxul Safe & Sound insulation

I should be able to share with you the outcome of this assembly... Once all is done!

good luck, what I am in the process of doing:

1) 5/8 fire rated - 2 layers with green glue between and GG noise sealant around
2) resilient channel though I went 16 oc even though the joists are 16 oc, your method is good
3) screws to make it through and grab the channel are all thats really needed.
4) I went with the denim insulation since it was on sale and I am always willing to try new things.

I did find a good spec sheet for guidelines on resilient channel, maybe it will help you as well.

I'm a little over half done and very happy so far. I have my work office in the basement and what I hear for voices above me now only come through the unfinished area. the extra mass also helps to deaden the clomping that we all know kids are great at too.

sounds good! screw the resilient channel with coarse thread screws and when screwing the drywall to the channel use the fine thread!

oodssoo 12-01-2012 04:48 PM

i actually used deck srews to install the RCs... the drill bit works a lot better than the normal phillips...

princelake 12-01-2012 05:38 PM

ya i'll never understand you americans and your phillips screws. the canadian red robertson is a far more superior screw head

drywall is not that hard.
