Air sealing an attic, home, or business space is critically important because it closes the gaps, cracks, and penetrations in the building’s envelope (the boundary between conditioned and unconditioned space) that allow conditioned air to leak out and unconditioned air to leak in. When combined with proper insulation, air sealing delivers numerous benefits.
Air leakage is a major cause of wasted energy. A typical home’s leaks can be equivalent to having a window open every day of the year!
Reduces HVAC Strain: When air leaks, your heating and cooling (HVAC) system has to work harder and run longer to maintain the desired temperature. This consumes more energy and increases utility bills.
Significant Cost Reduction: By air sealing and adding insulation, homeowners can save an average of 15% on heating and cooling costs (or about 11% on total energy costs).
Maximizes Insulation’s Effectiveness: Insulation alone is far less effective without air sealing. Air sealing acts like the windbreaker layer of a coat, stopping the airflow, while insulation is the fluffy layer that locks in warmth or coolness.
Enhanced Comfort and Consistency
Air leaks create uncomfortable living and working environments.
Moisture, Health, and Structural Protection
Air sealing helps control the movement of moisture and pollutants, protecting both the building and its occupants.
Extends HVAC Lifespan
Because a well-sealed building reduces the workload on your HVAC system, it operates more efficiently and experiences less wear and tear, potentially extending its lifespan and reducing the need for costly repairs or early replacement.
