Building a double stud wall help
« on: August 19, 2009, 02:37:15 PM »
We are in the process of building a recording studio ..   new construction...
  We are building a double stud wall...    this was our plan ... but we need to have a little
more space inside...
2 layers of 5/8" sheetrock with greenglue on the inside...
2x4 stud wall with greenglue to sheetrock...
pink insulation in stud wall
1 inch air space
2x4 stud wall with pink insulation
1/2" plywood
5/8" exterior drywall
firring strips 1/2"
Hardy siding..   

my question is .. if we double up the 5/8 on the outside
can we go any thinner on the interior wall? 
thanks Dwight in New Orleans

You could use 2 x 3's with a 1/2" space between walls with minimal loss in performance, especially if you add another layer of drywall.

Since you will have a double stud wall, you can skip the Green Glue with virtually no detrimental effect.  Remember to do good sealing...

Just want to toss my 2 cents in this tread, if your planning on recording with LF (bass) then I would recommend the green glue with a 3 tube formula per sheet of drywall.
Here's a link for you to review.
