What does air sealing primarily reduce?

Air sealing primarily reduces convection. Convection refers to the movement of air that can occur through gaps, cracks, and openings in a building's envelope. When air is allowed to move freely in and out of a home, it can result in uncomfortable drafts and increased energy costs due to heating and cooling systems working harder to maintain the desired indoor temperature.

By effectively sealing these air leaks, you minimize the unwanted airflow that contributes to convection. This leads to a more stable indoor environment, as air sealing helps maintain temperature consistency and reduces energy loss. In this way, it plays a crucial role in improving energy efficiency and comfort within a space.

While heat loss, noise pollution, and air pressure can also be affected by the sealing of a structure, they are not the primary focus of air sealing itself. Heat loss is more directly influenced by insulation and thermal barriers, while noise pollution pertains to acoustic treatments rather than air sealing specifically. Air pressure can be impacted by various factors including ventilation systems and weather conditions, but again, sealing is not primarily aimed at controlling air pressure.
