Renovation/Demo Sound proofing help

post #1 of 11

Thread Starter 
I would like to soundproof my upstairs from the downstairs. I recently purchased a home and have stripped the ceiling and walls to the beams. I have read a lot about resilient channels/z channels along with sound isolation clips, double drywall with greenglue, etc. There is a ton of information and I cant figure out what is best or if it is just promotional.

I would like to soundproof and hopefully reduce foot fall noise. Here are the specs:

1) Wood frame
2) Ceiling joists are 2x8
3) 8 ft ceilings

- Do you think I should drop and reframe the ceiling with metal studs?
- Use resilient channel? RC- 1, RC-2, 8 etc....I have no idea.
- Sound clips?

Thank you for your help!

Foot fall (impact) noise needs to be dealt with at the source ... IOW, in the floor itself.

The use of isolation clips, etc. on ceiling is helpful but more helpful in reducing the transmission of airborne sound from the room below to the room above.

Do not even think of using "Z" channel or Resilient Channel on a ceiling (and is not the best choice for walls in any case).

Dennis offers good advice there. You can look at the article above to get an understanding of the issue with footfall noise and some methods to deal with it.

Thank you for your reponse.

I will probably install carpet upstairs but would like some options while my ceiling downstairs is still open. Do you have any opinion on sound clips such as "genie clips" or "Americlips"? I spoke to a rep who sells genie clips and claims that the rubber "decupples" the ceiling - I am not sure if it is a sales answer or the truth.

Do you think I should drop the celing a few inches with metal studs, seperating the drywall from the joists?

Should I just install double drywall over the joists with Green glue?

Thanks!

The rubber does not decouple.

The rubber is less and less important the more the ceiling is loaded with damped mass.

The correct furring channel and correct clip spacing for a given load is much more of an issue than whether there is rubber on the clip or not.

I would ask people here what they have used and how they like the results.

Thank you - do you have any idea on who I should ask?
Perhaps dropping the ceiling would be best.

It does ... but not in this universe.

Yes, I did - thank you. I am going to go with using clips and a hat channel along with 2 layers of drywall. Any opinion on what clips I should buy? What is the best bang for the buck?

Best bang for the buck when using double (damped) drywall is to use the least expensive clip. To keep the forum commercial-free, feel free to send me a PM

Adding damped mass to the underside of the sub-floor as mentioned in Ted's article shouldn't be overlooked. Drywall is cheap. Read the Bethesda Build thread and contact Jesto.
