Hi guys... thanks a bunch for the feedback... and sorry that my initial description was so misleading...
We just started framing, so the pics are not a good representation of the design. We are definitely
not just using a single layered (or even a double-layered) wall between the CR and the Studio. The front wall of the CR will be a double wall. We'll have sheetrock followed by insulation followed by particle board and then a 2" (or so) space and then another wall of the same materials. The insulation will be R30.
There will be a quadruple paned window in the wall. Each "layer" will have its own double paned glass window, which we intend to have on a slight downward angle. (slanted forward into the CR, maybe?)
HVAC is not an issue in this environment. We only have two vents in the entire basement, and they will be treated accordingly.
I hope that gives you a better idea of what we're doing here. I appreciate the suggestions, and honestly, this
is part of our research, so any input is welcome.
I'd like to know more about that "Resiliant Channel" stuff. That sounds like something we would want to look into (to isolate the CR more).
Also, should we be using some other type of insulation (other than R30) such as Rockwool (something we've heard about).
...and should we use something other than particle board (like 3/4" plywood or some other material).
The main question we had (for this thread at least) was acoustic treatment. Once we've chosen the right materials and framed and isolated the CR and caulked the entire basement to death
then we need some ideas on how to treat the CR. So input on that is also welcome.
Thanks again for the help.
