Air sealing should be applied in areas where air leaks are most likely to occur, such as around windows, doors, and vents. Common gaps can be found where plumbing, electrical wiring, or ducts enter and exit the home, as well as around the attic hatch, basement, and crawl spaces. These are areas that often go unnoticed but can contribute to significant energy loss if not properly sealed. Special attention should be given to areas that are difficult to see, like gaps in the attic, which can let conditioned air escape while letting cold air in, leading to higher energy costs and reduced comfort.
In addition to the obvious gaps around windows and doors, sealing areas like ductwork and the spaces around chimneys or pipes can also significantly reduce drafts. Sealing these areas helps maintain the integrity of your HVAC system, preventing the loss of heated or cooled air as it moves through your home. Applying air sealing to areas where insulation is lacking or compromised ensures maximum efficiency, as it allows the insulation to work at its full potential. This creates a more comfortable and energy-efficient living space while reducing the workload of your heating and cooling systems.
