Feedback on creative ways to sound proof - insulate existing finished ceiling
Check out 4x8 sheets of &quot;sound board&quot; available in the lumber department of your big box stores. Using thermal insulation to muddle sound doesn't add up. My neighbor, a drywaller, put it up throughout his condo unit then drywalled over it. You could just screw it directly into your ceiling then add drywall on top of it. Electrical boxes would need box extensions but this is a lot easier and more to the point than trying to shove thermal insulation into narrow spaces filled with pipes, vents, conduit, romex, and maybe some speaker or other low voltage wires....and which only mitigates heat loss with a bit of sound insulation. Go for the real thing and don't let those cloggers get you down (sorry Geico, or whosever ad that is on tv)...
