X2. I would agree to insulate, but think of the cost to heat it. If you needed to tinker with it in the cold months, look into a propane fired torpedo heater. That would take the chill off in a short period of time. Also, place the windows in the normal position, the asthetics really do matter, over and sun issue. IMO
