About Master Flow™ Undereave Intake Vents - Aluminum

Located at the lowest portion of the roof, these easy-to-install vents are a critical part of the attic ventilation system, allowing the flow of fresh air into your attic. Screened aluminum soffit/undereave vents provide 26 - 50 sq. in. of NFA to allow cool, fresh air to enter the attic. Simple installation with pre-punched nail holes and surface-mount design.

Note: Always have a balanced ventilation system. In no case should the amount of exhaust ventilation exceed the amount of intake ventilation.
