The key to energy efficiency at home is proper insulation. Without insulation, your home would have a substantial number of air leaks, allowing heated or cooled air indoors to escape while leaving your home vulnerable to the elements. Proper insulation can also help to reduce the risk of moisture damage. Which areas in your home should be insulated? Here is what every homeowner needs to know.
Good insulation starts in the attic, which is the final barrier between the elements and your home. Typically, attics are insulated with loose-fill or batt-and-fill insulation , though loose-fill is often preferable because it can provide better coverage. The easiest way to find out if you have adequate insulation in your attic is to measure it. If you have less than 11 inches of fiberglass or rock wool or eight inches of cellulose material, you don’t have enough protection. Contact an insulation company to seal any existing air leaks and add additional insulation material.
Exterior Wall Insulation
Even if your attic is properly insulated, your home could be drafty during the winter months and too hot during the summer if your exterior walls lack insulation. Although adding insulation to exterior walls can be pricier than attic insulation, it is usually worth it given the long-term savings on your energy bills and the additional comfort you’ll enjoy in your home. If the only change you’re making to your home is adding insulation to your existing walls, spray-foam insulation is usually the best choice, because it requires the least amount of disruption for your walls. If you are remodeling your home or building a new home, your insulation company may recommend other types of insulation.
Basements should be insulated whether they are conditioned spaces or not, because of their close proximity to your living area. If you are building a new home, request that insulation be added to the exterior walls. In an existing basement, you can add insulation to the interior walls, since making changes to the exterior walls of a basement is not possible. Multiple types of insulation are ideal for basements, including batt and roll, loose-fill, and spray foam.
