multiply that by 2 for both sides of one wall and that is 2 1/2" plus 4" for the wood. so each wall comes out to be 6 1/2". |
So, your tracking room to control room wall is a 4 leaf wall assembly?
1.) room
2.) 5/8" gypsum
3.) 5/8" gypsum
4.) 2x4 stud
5.) 5/8" gypsum
6.) 5/8" gypsum
7.) 19" airgap
8.) 5/8" gypsum
9.) 5/8" gypsum
10.) 2x4 stud
11.) 5/8" gypsum
12.) 5/8" gypsum
13.) room
That 19" air gap is nice... but.... wtf???
If that's really the case, then I'm gonna say that you've got some serious isolation happening... and that you could have possibly had even more by not putting the 2 layers of gypsum in the gap.
But you prolly had reasons for that wide of a gap. That being the case, you probably could get away with residential windows and possibly save some money... but to gain optimal isolation, probably standard 1/4" laminated on each side is what I would use.
