Sound Proofing

My daughter owns a duplex and the middle wall was not insulated or anything so it transfer noise pretty bad. Will sound board and a second layer of sheetrock do anything or do just need to pull sheetrock and install sound batting?

Re: Sound Proofing

be best to create an air gap to break the sound transmission.

most common to use hat channel then your drywall.

it won't be perfect but it will be better

Re: Sound Proofing

If you double drywall it use green glue and you have to address any punctures in the wall such as outlets and any plumbing

Re: Sound Proofing

Quick and dirty is just have the wall blown with fiberglass. Drill and fill dense pack.

If you need more, then go with the hat channel and drywall.

Re: Sound Proofing

Did a lot of sound proofing in mansions in the Hamptons. We would use Roxul safe and sound inside the walls. Then 1/2" plywood, then a rubber product we called LV-1. I can't find this product though for a better name. It was 1/8th" thick and came on a roll 36" by about 75'. Then 5/8 sound board drywall. It was a purple board with a layer of fiberglass in the middle I believe. If you don't want to open the walls try the plywood and 5/8 drywall, you can get outlet extenders for the added thickness.

Re: Sound Proofing

Hey Randy there are a bunch of drywall types to cut down on noise my favorite is Quiet rock c/k out 530 or 545, 530 is 5/8 fire rated perfect for common walls.

Others, sound block, silent fx, I forget which one claimed their panel was the same as 8 layers of reg sheetrock.

These products are no cheap but remember this is not reg drywall some where in $70.00 for a 4x8 panel.

I read all the time about stuffing all kinds of things in the walls but most of these things are not for cutting down sound they are for stopping the loos of hat etc

I remember reading about a membrane that can be applied I think it was a Aussie invention ?.
