Author Topic: Any point in soundproofing bedroom ceiling? (it's only the attic above)  (Read 4822 times)

I'm planning on soundproofing one of my bedroom walls (townhouse common wall) with another layer of drywall with green glue. I'm also planning to do the exterior bedroom wall with green glue for exterior noise (window is already taken care of). While I'm at it, I'm considering doing the ceiling as well. Is there any point doing the ceiling to treat against exterior/neighbor noise, considering there is only an attic with 18" of blown-in cellulose above it? Also, my attic is isolated from the neighbor's attic. Thanks.

ct991,

I too will have a bedroom with the bed right up against a townhouse common wall, so I am interested in your progress.

How do you plan to handle the outlets and phone connections in the common wall.  It seemed to me that putting in extensions was a job for a contractor.  Do you plan to do the work yourself?

You mentioned the ceiling, but what about the floor.  I have read that the best constructed wall will be limited by flanking noise through the floor and ceiling.

You can always come back and do the ceiling later.  If you attics are isolated as well as you've said, I doubt you'll have too much noise transmission by that route.

I recommend you use 3/4" drywall with your Green Glue and for your outlets the best way to deal with those is using Puddy Pads to wrap the back of outlets and switchs. Since you have drywall already up you will have to cut out the drywall, wrap the back of the box,patch the drywall and caulk where the drywall meets the box. If you plan on adjusting the box the use Isolation Padding tape on the stud before re-attaching the box to the stud.

What are puddy pads? I googled but didn't get much. Do you mean putty pads?
