Making sure your home is well insulated is one of the best things you can do to boost energy efficiency and lower your utility bills. If you're planning to replace or supplement your home's insulation, it's important to know how to evaluate insulation, and which parts of your home need it the most.Where to startSome areas in your home are a higher priority than others when it comes to insulation. If you can invest in adding insulation to only one area, it should be your attic. Heat rises, and it can easily flow right out of your house if your attic doesn't have enough insulation.Other areasOf course, insulation should never end with your attic. An energy-efficient house should be well insulated throughout. A few other important areas include:
Floors, especially over an unheated garage
Basements and crawl spaces
Evaluating insulationBefore you add insulation to your home, you should get an idea of how much insulation you already have, and what types of insulation are being used in your house. There are a few ways to do this.
Contact a home energy auditor to perform a whole-house energy assessment, including an insulation check.
Inspect the insulation yourself in unfinished areas where it might be exposed. Good places to check include exposed floors and walls in your attic, basement and crawl space.
Inspect exterior walls through electrical outlets. To do this, first turn off the power to an outlet, then remove the outer cover. Shine a flashlight in to see the insulation, and remove a small piece if necessary.
R-valuesYou can judge the efficiency of new and existing insulation by its R-value. Insulation's R-value is a simple way to judge its resistance to heat conduction, and thus its efficiency. R-values are listed on the packaging when you purchase insulation. Most homes should be insulated with an R-value of at least R-30.For more information on adding insulation to your home, contact Air Assurance Heating and Air Conditioning.
