Attic vents are designed to facilitate airflow, which helps regulate temperature and moisture levels within an attic space. However, during colder months, these vents can become a source of heat loss, leading to increased energy consumption. Sealing these vents with a material like rigid foam can mitigate heat transfer and prevent drafts from entering the home. The process typically involves measuring the vent opening, cutting the rigid foam to size, and securing it in place using an appropriate adhesive or mechanical fasteners.
Effectively sealing attic vents offers several benefits. It reduces energy bills by minimizing heat loss, improves indoor comfort by eliminating drafts, and helps prevent moisture buildup that can lead to mold growth and structural damage. Historically, various methods have been employed to address heat loss through attic vents, ranging from simple fabric covers to more sophisticated insulation techniques. Rigid foam insulation is a popular choice due to its thermal resistance, ease of installation, and durability.
