I am confused with this point. What is it worth? I'm only concerned with isolation at the double wall.?
I am planning on boxing the outlets on both sides of the double wall and in addition, double 5/8 on that wall and on the adjacent bedroom wall and ceiling. Double 1/2" will let me install switch and outlet boxes without too much extra effort.
I'm not entirely sure why I want double sheetrock on the exterior walls at all. I'm on the fence about putty pads on the other outlets and boxing the lights. Will I hear any benefit from using them on exterior walls?
My reasons for not boxing the lights are as follows:
- Hatred of MDF dust
- Wife looks at me like I have completely lost my mind when I suggest it
- Fear of the reaction my backwoods electrical inspector will have when he sees them
- No rafter cavities are shared between the rooms
My reasons for boxing the lights:
- Better theoritical isolation
So let me summarize. I hate MDF dust enough that I am making up excuses to aviod it and I'm not convinced that 1/4" of drywall is worth the minor effort that I will have to exert in the electrical dept to gain it.

bpape is on the job; and is not a double wall preferable to staggered studs?
