Does Insulating Over a Garage Save Energy?

Insulating the area in the attic over a garage might keep the temperature a little more stable in the garage, but it does little to reduce the amount of energy needed to heat and cool your house, so it’s not a good investment of your energy dollars.

A much better use of your energy saving dollars would be to make sure you have at least 12” to 14” of insulation in the attic over the heated and cooled areas of your house.
