Depends on your budget and how much you are willing to spend on small increases in quality. As in Audio Gear, quality increases of 10% usually require a logarithmic increase in budget.

Sorry to bump this old thread, but

are you saying that a 2 decoupled leaf walls like this:

45mm of insulation (between 48mm steel studs)
20mm AIR GAP
45mm of insulation (between 48mm steel studs)
(layers of Fermacell/plasterboard etc)

would act worst than :

45mm of insulation (between 48mm steel studs)
20mm of insulation
45mm of insulation (between 48mm steel studs)
(layers of Fermacell/plasterboard etc)
