WHAT IS AIR SEALING?
Where Are the Air Leaks in Your House?
Air leaks can be located almost anywhere in a home, though some areas are more prone to leakage than others. Air leakage is a byproduct of home construction. During the assembly process, thousands of materials are joined together, and there is almost always a small gap between the place where two materials meet. By the time construction is complete, there are leakage points all over.
Up to 40% of Energy Loss in a Home Is Due to Air Leakage
In an average home, 25-40% of the energy used for heating and cooling is lost due to air leakage. This means you’re likely spending a lot more than you need to on energy costs.
Basements Air Leaks
Most basements have multiple air leak locations. Cracks in the foundation, gaps where floor joists are bolted together, and holes drilled to accommodate water lines, plumbing, electrical, and dryer vents all contribute to air leakage in a basement. These holes suck external air in and let heated or cooled air leak outside.
Attic Air Leaks
Sealing the attic is an important first course of action against air leakage. This is because rising heat forms a convection current that draws air up into the attic and then out through whatever openings exist. This creates a phenomenon called the stack effect, which draws air from below, creating a negative pressure that sucks in outside air through basement air leaks.
By sealing the attic, air is not allowed to escape, which then stops the upward airflow from transferring energy out of the house. Air sealing your attic will help you save energy year-round.
