Air sealing is the process of sealing gaps, cracks and leaks in the building envelope to prevent air leaks, which can result in energy loss, poor indoor air quality, and decreased comfort. It is a specialized skill that involves identifying air leakage points, selecting appropriate sealant materials, and applying them correctly to ensure that the building is airtight. Effective air sealing can improve energy efficiency, reduce utility bills, improve indoor air quality, and provide a more comfortable living environment.
