Which installation improves energy efficiency by sealing gaps in windows and doors?

Weather stripping is designed specifically to improve energy efficiency by sealing gaps around windows and doors. When these gaps are sealed, it helps prevent drafts, which can lead to heat loss during colder months and keep cool air inside during warmer months. This sealing reduces the amount of air infiltration, thereby lowering heating and cooling costs and enhancing overall comfort within a space.

While ventilation systems are crucial for maintaining air quality and ensuring adequate airflow, they do not directly address sealing gaps. Insulation foams are excellent for insulating walls, attics, and other spaces but are not typically applied directly around windows and doors. Heating panels, meanwhile, relate more to heating systems rather than energy efficiency through sealing drafts. Thus, weather stripping stands out as the most effective solution for this specific purpose.
