The Importance of Insulation & Air Sealing

Click here for a PDF version of this infographic

Many homes have insulation gaps and air leaks which lead to home comfort and efficiency issues. Insulation and air sealing work together to keep your home comfortable and energy efficient year-round.

How Insulation Works

Insulation acts as a thermal barrier that controls heat flow into and out of the home.

  • In the summer, insulation keeps outside heat from entering.

  • In the winter, insulation keeps inside heat from escaping.

How Air Sealing Works

Air sealing eliminates holes, cracks, and gaps which let air travel into and out of the attic.

  • In the summer, heat from the attic doesn’t seep into the home.

  • In the winter, valuable heat doesn’t escape into the attic.

Why Air Seal & Insulate Together?

Air sealing and insulation work hand in hand to resolve your home comfort and efficiency issues. Together, they provide benefits like:

  • Stable indoor temperatures

  • Greater overall comfort

  • Decreased energy usage

  • Lower energy bills

  • Healthier indoor air quality

Start with an Energy Audit

Proper insulation and air sealing starts with an energy audit to pinpoint problem areas. Your energy audit will include:

  • Blower Door Testing
    This test measures total air leakage in the home and makes it easier to pinpoint air leaks and insulation gaps.

  • Thermal Imaging
    An infrared camera allows you to locate problem areas like air leaks and missing insulation.

  • Audit Report
    This will include a list of recommended improvements, including where air sealing and insulation are needed.

Start your next air sealing and insulation upgrade off on the right foot with an energy audit.
