I'm building a workshop in an existing shed. It's near some adjacent flats so I want to insulate it for sound as well as heat. The shed is 10x17', t&g thickness unknown and the studs are 2" deep. I was thinking of stapling hardboard to the studs and squirting in expanding foam. I reckoned that his would be a fairly quick, cheap and effective way of insulating the walls and ceiling for sound and heat. And it'd be more fun than cutting up fibreglass board. However from reading some of the posts here it sounds like I should definitely be leaving an airgap to prevent rot.
Can anyone advise if this is really necessary or if my plan is flawed in some other way that I haven't thought of? The shed is probably only a few years old and is in good nick.
