The undereave vent is an intake vent that allows air to enter the attic. As an essential component of a ridge vent system, the undereave vent provides the other half of the air movement equation by creating a balanced attic.

According to most building codes, you need 1 square foot of ventilation for every 150 square feet of attic floor space. For new home construction that includes a vapor retarder, the minimum is 1 square foot of ventilation for every 300 square feet of attic floor space. If your vents are split between ridge vents and intake vents, the minimum requirement is also 1 square foot of ventilation for every 300 square feet of attic floor space.
