There are some areas in your Arizona home that obviously need insulation. There are, however, some less obvious areas that also should be insulated that you probably wouldn’t even think of. A particular area that should be insulated is your garage. Your garage leads directly to your home and without proper insulation in Arizona, hot and cold air drafts will seep into your home through your garage. This results in a waste of energy and a waste of money spent on your energy bill because your heater and air conditioner are forced to work overtime due to improper or not any insulation in your Arizona home garage. Other areas that should be insulated include: attic, walls and ceilings.
