Dear Friends,

Will varying the thickness of subsequent layers of drywall benefit a wall system in a similar manner to mismatching the size of each pane of glass in a double glass window construction?

SYSTEM #1
Floor-to-Ceiling 2x6 stud frame with 5/8" drywall (1st layer) then 1/2" drywall (2nd layer) or vice versa (any reason one way is better?)

SYSTEM #2
Floor-to-Ceiling 2x6 stud frame with 5/8" drywall (1st layer) then 5/8" drywall (2nd layer)

Which is the superior wall system when ISOLATION is the primary concern?
I assume #2 but want to know your thoughts.

Thanks!
