I'm looking to finish insulating my garage. it is attached to the house so one wall is already insulated. and I insulated another so it has two insulated and covered walls. My question is, would I be ok to insulate the side wall and the wall that the roll-up door is on and not insulate my ceiling, or would it be recommended to do the ceiling? Im mainly going to use it as my reloading room. There is no heating or cooling going to it right now. Thank you.
