MAC Posted August 19, 2007 Report Share Posted August 19, 2007 I live in a condo unit and want to sound proof to dampen and/or eliminate sound from neighbors. I've been doing some research and it looks like using Green Glue between two or more sheets of drywall is very effective and reasonably priced in comparison to other sound proofing methods. I'm curious if anyone has used Green Glue? Link to comment Share on other sites More sharing options...

MAC Posted August 19, 2007 Author Report Share Posted August 19, 2007 Are you removing drywall? I'm probably going to remove drywall. I'm thinking about two sheets of of 1/4-inch drywall with Green Glue in between or 1 sheet of 1/2-inch and 1 sheet of 1/4-inch with Green Glue. The original drywall is 5/8-inch. I don't want to use 2 sheets of 5/8-inch because I'll loose living space--I want to keep as much living space as possible. If I remove drywall I think there are other things I can do to enhance sound proofing but it may not be worth the expense. I know there is tape and natural fiber insulation but the insulation is expensive. Link to comment Share on other sites More sharing options...
BodybyFisher Posted August 19, 2007 Report Share Posted August 19, 2007 If you are going to tear out the sheetrock you can use acoustic insulation, when we renovated the house I insulated the master bedroom with acoustic insulation on all 4 walls.

Ranger Posted August 19, 2007 Report Share Posted August 19, 2007 That's what I was going to suggest. If your removing drywall, why not just put some rolled insulation in the wall. That should do it. Link to comment Share on other sites More sharing options...
MAC Posted August 19, 2007 Author Report Share Posted August 19, 2007 Thanks for the ideas. I'm going to price BBF's suggestion regarding the Johns Manville fiberglass insulation, but also its Whispertone ("WT") Micromat and Whispertone Wallboard. I tend to believe the WT Micromat and Wallboard are too expensive so I'll just go with fiberglass insulation and Green Glue some standard gypsum wallboard. The problem is that my downstairs neighbor (Association tenants) have a washer and possibly dryer--At least it sounds like they do in their half-bath. The sound travels up the wall into my unit. It can be annoying, especially when their washing cloths at 11:00 p.m. I could complain but since I also hear the bathroom fan and generally want to eliminate sound coming from the unit, I figured I would look into soundproofing. The Association's last tenant was noisy to the point where I went down and knocked on their door at about 12:30 a.m. Anyway, in the long run I tend to believe soundproofing will help to add to the resale value of my unit?

Ranger Posted August 19, 2007 Report Share Posted August 19, 2007 This MAY NOT help since it is a "downstairs" vs next door. The insulation would be better in their ceiling (your floor). I used to rotate shifts and when I worked mids and my kids were small, I could hear everything from the kitchen below my bedroom. Always swore if I ever built another 2 story I'd insulate the ceilings. Link to comment Share on other sites More sharing options...

I think if you highlight the soundproofing and how bad it was without it, it would help the sale. But they have no point of reference to appreciate it, like you will. You may be surprised that its not too expensive, and even if it is, its something you will appreciate over time. Its sort of like the difference between good tires and GREAT tires if you know what I mean.

WarrenJ Posted August 19, 2007 Report Share Posted August 19, 2007 . . . . when we renovated the house I insulated the master bedroom with acoustic insulation on all 4 walls. And this was to keep noise OUT or IN . . . ? Sorry, just couldn't help.

MAC Posted August 20, 2007 Author Report Share Posted August 20, 2007 From what I have read it appears the effectiveness of Green Glue is due to its viscoelastic properties, which allow the glue to dissipate sound by converting it into heat, which from a physics standpoint has been proven. Now for my question: Would anyone happen to know if Visco Foam/Memory Foam, which is viscoelastic (from what I have read), be used as insulation inside walls between joists to help deaden sound? Memory Foam comes in many thicknesses which I'm thinking may be an effective way to supplement acoustic insulation. Link to comment Share on other sites More sharing options...
Texas Jim Posted August 21, 2007 Report Share Posted August 21, 2007 I live in a condo unit and want to sound proof to dampen and/or eliminate sound from neighbors. I've been doing some research and it looks like using Green Glue between two or more sheets of drywall is very effective and reasonably priced in comparison to other sound proofing methods. I'm curious if anyone has used Green Glue? Mac, In reading over this thread, it seems like the sound is coming up thru the walls from the lower unit to your unit. If I read it right, have you tried the old broomstick to the ear method of listening to the wall to see "EXACTLY" where in the wall it is coming from? If it is from a specific location, it may be traveling thru the water or vent pipes for the plumbing. "IF" that is correct, you may have to only tear out the one piece of drywall in your place that covers all the plumbing pipes. If the pipes are touching your floor in any way or touching the studs in your wall... the sound will be transmitted from their place to yours. If that turns out to be the case... center the pipes in the holes, put foam backing between the pipes and your studs and insulate all around them. A LOT. Just a random thought.

If I read it right, have you tried the old broomstick to the ear method of listening to the wall to see "EXACTLY" where in the wall it is coming from? If it is from a specific location, it may be traveling thru the water or vent pipes for the plumbing. I never heard of putting a broom stick to the ear. I did put my ear to the wall and it's obvious the sound is indeed shooting up the wall. It's annoying. I think it might be the bathroom fan or even a washer--Don't know for sure. Last year I complained about the bathroom fan and the Association replaced it with a quite (low decibel) fan and things are much better. Now, I'm not sure what's going on because noise is back. So I'm thinking it could be the other fan in the half-bath? I'm thinking about complaining again but I'm willing to pay for a new quite fan (like I offered to do last year) for them in an effort to work out the problem--Assuming it's the fan. My desire is to have peace in quite in my unit. I'm definitely going to buy Green Glue--I just want to research other options that will help augment sound proofing, including wall insulation, which will provide additional 3-4 Sound Transmission Class (STC) points.

Patrick7997 Posted August 21, 2007 Report Share Posted August 21, 2007 Texas Jim is right.... sounds coming from the bathroom typically are being transmitted by plumbing, or by openings in walls where the plumbing runs in common behind... I might explore his ideas of packing your pipes, checking that out... that quieted down my condo considerably.... easier than re-wallboarding. Start with that. I don't know anything about green glue... but in a place I used to live, I insulated the wall, and re-wallboarded with 5/8th firecode drywall... great results.
