Air Leakage Problems


Air leakage is a major source of energy loss as well as discomfort in many homes. Common areas of air leakage include kneewalls, recessed lights, attic hatches, windows and doors, flue and duct chase ways, vents, wiring holes, cantilevers, band and rim joists, etc. Besides the cost and comfort issues, air leakage also contributes to issues with indoor air quality by allowing moisture, mold and dust to enter inside conditioned space from the attic, crawlspace and outside.

Air Leakage Solutions


Air-sealing (followed by insulation) remains the key to “Step 1” home energy efficiency. One of the most common mistakes homeowners make is adding insulation without air-sealing the envelope first. Insulation cannot stop air movement! In fact, fiberglass, cellulose, and the vast majority of insulation materials are designed as nothing more than a filter. Air is not “trapped” in the filter, it is just slowed. Over time, insulation will reflect this filtering effect by looking dirty.
