You may be surprised to know that the attic is one area of your home that can actually offer significant energy savings. Without the proper amount of attic insulation in place to trap the air in your home, the money you’ve invested in utility bills might as well be tossed out the window, or more precisely…out the roof.
You may be questioning how an area that is only used for storage purposes can be so important to your home’s energy efficiency. Proper attic insulation and ventilation play major roles in controlling the temperature and overall comfort level in your home during all seasons. Attic insulation is a critical component of keeping cool air in your home during the hot months and warm air in your home throughout the heating season.
If air is getting out through your attic, your HVAC system has to run longer to heat or cool your home, requiring more energy. Putting in additional or higher quality attic insulation will aid in keeping the air in the home and stop your heating/cooling system from having to operate as long or as often, saving energy and money by decreasing your utility bills. Cost savings fluctuate based on a variety of factors, like residents’ habits, whether you have a smart thermostat, and the type of heating/cooling system you have. On average, it is estimated that homeowners can save up to 20% on energy bills with the adequate amount of attic insulation. No matter where you live in North America, proper attic insulation helps in reducing the general wear and tear on your heating and cooling system.
Now that you understand the importance of a properly insulated attic, you may be thinking about what type of attic insulation is best for your home.
Insulation is rated in terms of thermal resistance, known as R-Value. The higher the R-Value, the better the insulating power. The amount of insulation recommended for your home is largely dependent on where you live, but as a general guideline, homes in a cold climate should have a minimum of R-49 in the attic and warmer climates only require an R-38. Here are the three main types of attic insulation available:
Many homeowners think of their home’s insulation as a “one and done” event. It’s true that under ideal conditions, your home’s insulation has a life expectancy of 100 years or more. But as your insulation ages, it undergoes changes. Most experts, including those at the U.S. Department of Energy, recommend that you have your insulation inspected at least once a year. If your roof has had to be repaired or replaced because of leaks, you should definitely make sure to have an attic insulation inspection. If your attic is currently insulated, you may want to find out when the insulation was installed to ensure it meets the EPA guidelines for energy efficiency. Also, if the product has compressed, it could be ineffective.
