LOL Stick... When we first looked at the house, there were no walls on the studs inside the shed, but when we went back, someone had put walls up. My guess is that it's NOT insulated. But with the time of year it was when we moved in, and the need to get our stuff out of the storage units that were costing us $200/mo, I'm putting my faith in the heater we have, (that's doing a great job, so far). I think when the good weather gets here, we're gonna take off the interior plywood put on the studs and see what's what.
Get your facts first, then you can distort them as you please.
