Rettrofit / insulate floor built on old asphalt driveway
Garage was turned into bedroom (before I owned house) but floor appears to be 2x4 joists with blue sold foam just sitting on the asphalt driveway. Should I fit the joists with vapour barrier and then have them sprayed or would I be better off just using sold foam? Can't afford to tear down and start again. Looking for best solution.
