Insulating wall between condo units
« on: April 20, 2012, 07:13:28 PM »
I am having some noise issues in a condo I recently moved into.

I can hear my neighbors through my wall. What I hear is basically a muffled " hum humm  hummmm" sound.  I think it's just regular talking or a TV.

The condo is concrete but the wall separating my unit from my neighbors is drywall. I opened up the wall and discovered:

- Double-stud construction (should be even better than a staggered stud wall)
- NO insulation (Why would they go through the effort of a double-stud wall and not install any insulation?)
- Only single layer of drive-wall on my side of the wall (I suspect the other side is also only a single layer as well)

Since the walls are decoupled (unless it has been shorted out somewhere) I think adding insulation would make a big difference. What is the best way of doing this? I have nice crown moldings and baseboards that I do not want to rip out. Would it be possible to blown-in fiber insulation? Alternatively, I could remove the entire drive wall from about a foot up from the floor and a foot down from the ceiling and install batt insulation.

you should put in cotton fiber insulation in both walls...address outlets and switches with putty pads on the backs..and since your putting in the effort you might as well just do it right and hang a layer of 1/8" MLV caulked and sealed, and finally 5/8" me it will be worth every bit money and work invested. You are in better shape than most people in similar situations, so take advantage of it....
