Air sealing and adding insulation to your home is a good way to reduce your energy usage, energy bills, and make your home more comfortable. In fact, if you added up all the gaps, leaks, holes in your house it would be the equivalent of leaving a window open every day of the year. Both air sealing and insulating your home is the best way to protect your house from those gaps, leaks, and holes. Insulation will act like a wool sweater by keeping you warm but it will not stop the wind; while air sealing will act like a windbreaker and protect you from the wind.
Adding insulation to your home will keep the warm air in your house during the winter and the cold air in the house during the summer, saving you money and keeping your home more comfortable. Insulation alone can’t stop air flow and this is why it is important to also air seal. It is important not to do one without the other.
Windows and doors are common places for leaks, but did you know that attics, crawl spaces, and basements can be a bigger problem? Attics, crawl spaces, and basements are places that we usually don’t spend a lot of time in, but they are still important in the overall energy efficiency of your home. Common places in attics that that can cause air leaks are around chimneys, cracks by lights, holes were wires are fed through, and many other areas. One way to tell if heat is escaping and that you need more insulation and air sealing is to watch if ice dams form on your roof during the winter.
Since we don’t spend a lot of time in attics, crawl spaces, and basements, it is hard for us to know if there are holes, cracks, or leaks in these areas. Here at 401(e), when we do home assessments we inspect those areas, looking for anything that might be losing energy. We also use specialized equipment like an infrared camera, and do a blower door test to find all the hard-to-see leaks in your house.
If you want an easy way to save energy, the best way is to insulate and air seal your home. This will not only keep you warmer in the winter and cooler in the summer, but will also help make your home more comfortable while saving you money.
