Drywall over plywood

Need advice:

I live in a house where my living room wall is right up against my neighbors wall (very common in Sam Francisco). I would like to make my living room wall a little more sound proof so I won't bug my neighbor and currently the wall only has plywood. I read somewhere that adding a piece of drywall over it will help. Any truth to it?

Drywall over plywood

It should be done if the wall only has plywood, especially for fire ratings. Will not stop sound, unless you use Green Glue between the sections.


Ren: Now listen, Cadet. I've got a job for you. See this button? Ren: Don't touch it! It's the History Eraser button, you fool! Stimpy: So what'll happen? Ren: That's just it. We don't know. Maybe something bad, maybe something good. I guess we'll never know, 'cause you're going to guard it. You won't touch it, will you?

Drywall over plywood

We used this...


on a project and it worked very well. It is basically a panel that is assembled at the factory with a layer of material similar to the Green Glue that gregzoll mentions sandwiched between 2 sheets of drywall. Finished thickness is 5/8.

Drywall over plywood

Better and cheaper to use two sheets of standard 5/8" drywall and a field application of damping compound. You want all the mass you can get and pre-damped specialty drywall are lightweight.

Also drywall from Home Depot is $7 a sheet.
