Making the basement into a seperate room/apartment and unfortunately you could hear stuff going on upstairs.

I’m looking into the fiber glass insulation, but I would have to cut open the ceiling and stuff it in there.

Does anyone have any experience with the ceiling tiles or whatever those things are which just get glued on? How well does that work? Also, does your ceiling then look like an office because it resembles a drop ceiling?

Final option is another layer of sheetrock. I’ve been told that works better than anything Any experience?

Thanks
posted this in your main forum post, but whatever…

Safe and Sound insulation by ROXUL, 30-50 bucks per bundle, so really depends on how big your ceiling is. Then go with 3/8s drywall, OR if you want it really quiet and don’t mind spending the extra money, they make drywall that has a thin membrane built in, one sheet supposedly equals the sound deadening of 8 regular sheets of drywall.

Or put up the roxul, then get some GOOD sound deadening hanging tiles. Probably be cheaper, but not nearly as effective, as the drywall.

Plus any mechanical/electrical/plumbing will still be easily accessible.

is it hanging tiles on the ceiling right now or dry wall?
If you absolutely DO NOT want to take down the existing ceiling to insulate you can put a second layer of drywall, but it wont be nearly as effective as insulating, unless you get the sound proof (ie: quiet rock) dry wall
Thanks… I have drywall on the ceiling now and I doubt there is any insulation there. Pretty sure there is none actually… I can feel some vibrations and hear people walking upstairs. I have about 350 sq ft of ceiling to cover. I want to do this quick but tearing up the ceiling is too much work.. I considered opening up one long gap along the ceiling then sliding the insulation in there and closing the gap up but I’m concerned that the insulation won’t be laying down flat in all parts.
Does it need to lay flat in all parts? If you get most of it covered, a couple little spots where it’s not even aren’t going to stand out. If you open up a long gap, make sure it’s going perpendicular to the direction that the joists run.
i wonder if you could put a layer of dynamat(what they use in cars fro sound dedning) or spray a layer of car undercoat then another layer of shhetrock.

That’s likely not very cost effective, but you never know.

I’m going to be sound proofing my basement as part of my renos, and I’m using Safe & Sound by Roxul. Probably decent bang for the buck.
Well…

We opened the middle of the ceiling (removed two middle sheetrock pieces). One of them was like 14 ft. never seen it that long.. anyways.. Bought 5 rolls of 80 sq ft thickest fiberglass insulation I could find and put them inside and closed it back up. Can’t tell yet but already seems a lot more quiet although I can still feel/hear some vibration and some creaking from the upstairs hardwood floor.

Total cost of insulation was about $160 and i reused the same sheetrock.
