Closing attic vents is often conducted during colder months to prevent heat loss and drafts. This process typically involves cutting rigid foam board to fit snugly over the vent opening and then sealing it in place with caulk or tape. The goal is to create an airtight barrier that minimizes air leakage from the conditioned living space into the unconditioned attic.
Properly sealing attic vents contributes significantly to improved energy efficiency. By reducing heat loss, heating costs can be lowered, and the overall comfort of the building increased. Historically, various methods have been employed to insulate attics; however, rigid foam has become a favored material due to its insulating properties, ease of use, and durability. The practice also helps to prevent moisture condensation, further safeguarding the building structure.
