Your attic is probably a part of your house you don't give much thought to. Out of sight, out of mind, right? Even though you may not be thinking about your attic, it's constantly affecting the temperature in your house. Improper ventilation and temperature control can make your entire house too hot or too cold. This, in turn, will cause you to use your heater or air conditioning far more than necessary. Taking the necessary steps to control the temperature in your attic won't be easy but will pay dividends in the long run.
Install insulation under the attic floors to keep the attic from getting too hot or too cold. The insulation will trap heat instead of letting the heat dissipate to other parts of the home. This will keep the attic and your house cooler during those hot summer months.
Lay down vapor guards over the insulation to keep it dry. Continuous contact with moisture will eventually cause your insulation to lose its ability to absorb heat. Vapor guards come in several types including plastic sheets and aluminum foil sheets.
Install a vent to allow air in the attic. A stuffy attic that is poorly ventilated will trap the heat or the cold, depending on the time of year. There are several types of vents to choose from. The most common are gable vents which look like windows with wooden blinds. The most efficient vents are soffit vents and are installed under a roof overhang.
Install a power ventilator on your roof. A power ventilator is essentially a strong fan that will suck the hot air from the attic and keep a constant circulation of fresh air going. These are particularly helpful for people living in hot regions such as deserts.
