Soffit Vents

Improve Airflow and Energy Efficiency

Soffit vents, also known as eave vents, provide proper ventilation by allowing fresh air to enter the attic or ceiling space of a home or building. This airflow helps regulate the temperature and moisture levels in the attic, preventing issues like mold growth and heat buildup. 

FAMCO soffit vents are available in various materials like galvanized steel, aluminum, and high-density plastics. We offer multiple styles to suit both residential and commercial ventilation needs.

Frequently Asked Questions

Soffit vents allow fresh air into the attic or ceiling space of a building, ensuring proper ventilation. This airflow helps regulate temperature and moisture levels, preventing issues like mold growth, heat buildup, and moisture damage. Soffit vents also support ventilation for exhaust systems, like bathroom and kitchen exhausts, contributing to a continuous flow of air that promotes healthy indoor air quality.

When selecting the right soffit vent, consider factors such as the size of the area needing ventilation, the type of building or home, and the specific ventilation requirements. Make sure the vent is compatible with the roof structure, and choose a material (such as plastic or aluminum) that offers durability and resistance to the elements.
