Soundproofing a common wall in semi-detached
« on: March 14, 2010, 12:41:04 PM »
I purchased a semi-detached house which is currently in stud phase so I have an opportunity to improve the soundproofing on the common wall (my side only).
I have read quite a bit about soundproofing on the Internet but there is almost too much information. I am wondering what is the best choice (or choices) between the best available materials.
The current design is double wood stud wall (about 2" apart) with double batts of pink fiberglass insulation and 2 layers of 5/8" fire-rated drywall on each side.
I have ruled out Roxul soundproof insulation (not much improvement over R13 pink) and resilient channels (installation problems)
I narrowed down my choices to use one or both of these:

Green glue between the 2 sheets of drywall
Quietrock drywall (or similar product) to replace one layer

Any thoughts on what would be the most effective for the dollar?
What improvement would I notice if I used both? (Is it like adding memory to a computer - you can double the memory and only notice a 10% performance gain?)
Thanks for any advice you can offer.
