All, I'm considering building an outbuilding (either metal building or pole barn) for equipment/vehicle cold storage. This is at a secondary property and I don't believe it would be worthwhile to heat it other than when I am there. So, it will be unheated for a fair amount of time. In Upstate NY we get a lot of snow.
I saw some reference to unheated concrete floors heaving in these conditions. The entire space will be unheated most of the time, and I suppose since it will be unheated most of the time there probably isn't much point in insulating it. Thoughts about this? I would like to put a loft in that is occasionally used as living space.
I'm looking for everyone's input.
Also for a large building (ie 40x60) what is the most effective way to heat it up on demand? I was thinking about something wood fired.
