How Does Air Sealing Work?

Air sealing is the process of closing off cracks and openings that allow air flow into a home from outside.  Many existing homes are not properly air sealed, which reduces comfort while increasing heating and cooling costs.  Properly sealing a home is a low cost improvement that homeowners can make that will often decrease heating and cooling costs by up to 20%.  A homeowner should always conduct air sealing before adding more insulation to their home.  Otherwise, unconditioned air will simply bypass the new insulation like a heavy jacket with an open zipper in the front.
