The thing about insulation is when does the cost of the insulation outweigh the gains from it? The general savings from those insulated blankets are around 10%. Yes you can add a lot more insulation and get even better savings. But if you either don't have the additional insulation laying around or can't get it for free it is generally not cost effective.
