I have a room that is partially situated over my garage. It seems to be the hardest room in our 2-story house to keep cool in the summer time and warm in the winter time. All the walls are insulated and the attic is too. I tried adjusting vents on 1st level to try to compensate, but did not work. I have central air cooling and heating, no heat pump. About 1/2 of the walls in the garage are insulated (the ones that adjoin the house). I have an insulated garage door, but the garage still gets extremely hot in the summer and cold in winter. I am planning to insulate the rest of the garage by the end of this summer. Is there something else I could do or a product to get that might help my situation?
Thanks in advance for any replies.
