Air Sealing and Insulation
Sealing and insulating the "envelope" or "shell" of your home – its outer walls, ceiling, windows, doors, and floors – is often the most cost effective way to improve energy efficiency and comfort.
Many air leaks and drafts are easy to find because they are easy to feel – like those around windows and doors. But holes hidden in attics, basements, and crawlspaces are usually bigger problems. Sealing these leaks with caulk, spray foam, or weather stripping will have a great impact on improving your comfort and reducing utility bills.
Insulation keeps your home warm in the winter and cool in the summer. There are several common types of insulation – fiberglass, cellulose, rigid foam board, and spray foam. Reflective insulation is another insulating product which can help save energy in hot, sunny climates. When correctly installed with air sealing, each type of insulation can deliver comfort and lower energy bills during the hottest and coldest times of the year. To get the biggest savings, the easiest place to add insulation is usually in the attic.
