Does anyone know of a good source of information on the design and construction of double walls? I found a little information in “Graphic Guide to Frame Construction” by Rob Thallon but it left me with a lot of unanswered questions and I would like to find a more comprehensive work on the subject.

I am currently building a house now using double wall construction. My technique is to frame outside wall, 2x4s, plates, studs, headers etc @ 24" centers. Snap to a 3-1/2" line off the outside of wall. Next wall is framed the same except studs are off set 12" from first wall studs. Line snapped at 7-1/4" inside. Top plate use a 2x8. With blown in cells, I have a good effective R-value of 22-25/inch or better.
I tried to add a photo or two but no such luck. If you have specific questions, I will try to help
A long ago poster, Gene Leger was a proponent of this.
Some of his buildings are in a book on superinsulated houses I have somewhere.
This may be it, maybe not too.

A double wall for soundproofing or insulation purposes?
I know I've been reading quite a bit lately on the practice of framing a "double wall" by using 2x8 plates and 2x6 alternated studs.
If this is what your talking about, do a search for "soundproof walls" on the internet. You should come up with a bunch of info.
