What is the purpose of weather stripping in buildings?

Weather stripping serves a critical function in buildings by sealing gaps and cracks around doors and windows to prevent air infiltration. This process is essential for maintaining energy efficiency within the structure. When weather stripping is properly installed, it reduces drafts, minimizes heat loss during colder months, and keeps cooled air inside during warmer months. This not only contributes to a more comfortable indoor environment but also lowers energy bills by reducing the workload on heating and cooling systems.

By blocking unwanted air flow, weather stripping plays a vital role in regulating temperature and reducing the risk of moisture problems, which can lead to mold growth and structural damage over time. While enhancing aesthetics, providing structural support, and improving indoor air quality are all important considerations in building design and maintenance, they are not the primary functions of weather stripping. The main focus is on sealing and energy conservation.
