The Magic of Air Sealing a House
For most insulation to be effective, air sealing is needed to stop the flow of air.
Air Sealing Benefits in Maryland
Air sealing a house is one of the most important home improvement measures a homeowner can take to increase energy efficiency as well as comfort around the entire home. In fact, by air sealing your house you can legitimately add years of service to your HVAC machine (because it won't have to work as hard) and you can eliminate paying for projects that won't fix your issues unless air sealing is complete. Air sealing a house is definitely a place a Maryland homeowner should start if they are serious about having a comfortable home.
The best air leakage points to seal are at the top and bottom of your house. Typical air leak points include light fixtures, walls/floors, ducts, fireplace openings, plumbing penetrations and light fixtures. Basement air leakage should also be considered equally important to attic air sealing. These air leakage points are in the areas of the home where pressure is greatest causing the holes to do the most “damage”.
