When your heating and cooling bills are higher than expected, it's time to have an energy audit done on your home. Your house may be losing close to 40 percent of the energy used to heat or cool your home through air leaks. Spray foam helps to seal up air leaks, filling in holes and acting as a barrier in the small nooks where air is escaping in your home. According to the Environmental Protection Agency, you can save about 15 percent on your heating and cooling costs just by having your home insulated.
Understanding Air Leaks in Your Home
You don't have to feel a breeze coming in through a window to have an air leak. Each leak in your home may be small, but when you have many small leaks, the total effect on your energy bills adds up. An energy-audit company can come to your home and assess each room of your home to determine where air leaks are coming from. While some areas may be obvious, such as an attic that isn't insulated, you may be surprised to learn how much air leaks from a window that wasn't properly sealed.
The Kinds of Spray Foam Used in Your Home to Prevent Air Leaks
There are basically three main types of spray foam that are used for insulating purposes inside and outside your home. High-density foam is used on exterior surfaces, especially on your roof when it is being installed. A medium-density foam provides continuous insulation, and it's used to fill in areas on the inside of your home, such as in attics that aren't vented. The low-density foam is used to fill in crawl spaces to help keep the home from losing too much air.
Sealing Cracks and Gaps in Your Home
Sometimes an air leak isn't as huge as a crawl space that isn't insulated. Air leaks can be around doorways, pipes that lead out of your home, and basically any exit out of your home. Spray foam can be used to close up these leaks, seal up the cracks, and fill in small gaps throughout your home. When you fix air leaks both big and small, you will make the most impact on your energy bills.
If you believe your home is losing money because of air leaks, it's time to get a home energy audit done to determine what fixes can be made to make your home more energy efficient.
