Air leakage in a home is a common but often underestimated problem. It compromises the comfort of your living space. It also significantly increases energy costs by forcing your heating and cooling systems to work harder. Sealing these leaks, particularly with an innovative aerosol solution, can dramatically enhance home comfort and energy efficiency. In this article, we’ll explore why air leakage matters. We will dive into how it affects your home and the benefits of using an aerosol sealant to address this issue.

Understanding Air Leakage

Air leakage occurs when outside air enters and conditioned air leaves your house uncontrollably through cracks and openings. Common leakage points include windows, doors, attic hatches, and various nooks and crannies throughout the building’s envelope. During winter, warm indoor air escapes from these openings. In the summer, hot outside air seeps in, compromising the comfort of your home.

The Impact of Air Leakage

  1. Increased Energy Consumption: Uncontrolled air leaks make it difficult to maintain a consistent indoor temperature.  This results in increased use of heating and cooling systems and, consequently, higher utility bills.
  2. Reduced Comfort: Leaks lead to drafts, hot or cold spots throughout your home, contributing to a less comfortable living environment.
  3. Compromised Air Quality: Along with air, moisture and pollutants can enter your home, potentially causing health issues and discomfort.
  4. Strain on HVAC Systems: As air escapes, your HVAC system has to work harder to heat or cool your home. This leads to more frequent repairs and a shorter lifespan for your equipment.

Aerosol Solutions: A Modern Approach to Sealing Leaks

This is due to their efficiency, ease of use, and effectiveness. An aerosol sealant works by releasing a fog of sealant particles into the air of a pressurized home. As the air escapes through leaks, it carries the particles to the openings, where they stick and seal the leak.

How Aerosol Sealing Works:

  1. Preparation: Before applying the aerosol sealant, a technician will conduct a blower door test. This test will provide a baseline of the initial air leakage rate of your home. All necessary systems are then shut off to prepare for sealing.
  2. Sealing: The aerosol particles are pumped into the home using professional equipment. As the home is pressurized, these particles flow toward the leaks, where they accumulate and seal the cracks.
  3. Verification: After the process, another blower door test is performed.  We now measure the effectiveness of the sealing, with results often showing up to a 90% reduction in leakage.

Benefits of Aerosol Air Sealing

  • Enhanced Comfort: Sealing leaks with an aerosol solution significantly reduces drafts and cold spots. This will help you maintain a consistent and comfortable indoor environment.
  • Lower Energy Bills: By improving the air tightness of your home you will soon see a reduction on energy bills. Aerosol sealing can reduce heating and cooling costs by up to 30%, according to the U.S. Department of Energy.
  • Improved Air Quality: Sealing leaks helps prevent the infiltration of moisture, dust, and allergens. This will contribute to healthier indoor air quality.
  • Prolonged HVAC Lifespan: With reduced air leakage, your HVAC system can operate more efficiently. Those systems will experience less wear and tear and requiring fewer repairs.
  • Increased Property Value: Homes with better insulation and air-sealing scores often fetch higher prices on the market. Savy buyers are drawn to their enhanced efficiency and comfort.
