Air Sealing

 What is Air Sealing?

Air sealing is a system of techniques we use to prevent air leaks in the home from occurring.  It helps to keep warm air from leaving the home during the winter and also stops cooler air inside during the summer. A properly air sealed home is an energy efficient home.

Air Leakage

Air leakage occurs when outside air enters, and conditioned air leaves the home through cracks and openings.

 

Why is Air Sealing Important?

First of all, most of homes built after 1980 have insulation in the attic which reduces heat loss. However, it won’t stop air flow from occurring. Insulation covers holes, cracks, and gaps through which forced air from the home is directed into the attic.

Stained insulation is an indicator of leaking air. A home that leaks air has higher energy bills, contains mold, and excess moisture. In conclusion, a home that has been properly air sealed won’t lose air and is comfortable throughout the home, 365 days a year.
