What is the purpose of air sealing in homes?

The primary purpose of air sealing in homes is to reduce heat flow and minimize energy loss. When air leaks occur in a building, warm or cool air can escape, leading to increased energy consumption as heating and cooling systems work harder to maintain comfortable indoor temperatures. By effectively sealing these leaks, homeowners can improve overall energy efficiency, maintain consistent indoor climates, and potentially lower utility bills.

Additionally, effective air sealing complements insulation, creating a more effective thermal barrier that minimizes unwanted heat transfer. This contributes to the home’s comfort and longevity of the HVAC system, as it does not have to work excessively due to air leakage. This understanding emphasizes the importance of air sealing as a critical component in energy conservation efforts within residential buildings.
