Air sealing primarily aims to reduce which of the following?

Air sealing primarily aims to reduce air leaks within a building. This process involves identifying and sealing openings and cracks in the building envelope where air can escape or enter. By minimizing these air leaks, air sealing enhances energy efficiency, improves indoor air quality, and increases overall comfort within the space.

When air leaks are reduced, it helps maintain a consistent indoor temperature, as conditioned air does not easily escape, and outside air is less likely to infiltrate. This has a direct impact on heating and cooling costs, ultimately leading to a more energy-efficient home or building.

In contrast, while managing moisture levels indoors, reducing thermal bridging (areas of a building where heat is transferred faster than other areas), and addressing temperature differences can be important aspects of building performance, they are not the primary focus of air sealing. Air sealing specifically targets air movement, making it the most relevant choice in this context.
