Foundation vents are openings that are installed in the foundation walls of a building to allow for proper ventilation in the crawl space or basement area beneath the home. These vents are typically installed at regular intervals around the perimeter of the foundation, and they can come in a variety of different shapes and sizes depending on the specific needs of the building.

Frequently Asked Questions
Can Foundation Vents be used for intake as well as exhaust?
Foundation Vents provide passive air exchange through foundation or crawl-space walls; the complete ventilation design determines the direction of flow.
How should airflow capacity be evaluated for Foundation Vents?
The airflow capacity for foundation vents is evaluated in net free area (square inches). Using this information, you can determine how many vents are needed for the area being ventilated. The ratio of NFA to ventilated area varies depending on the building's location.
How are Foundation Vents fitted?
The fit and installation of the vent vary greatly depending on the material and style of the building in which it will be installed. In general, match the vent dimensions to the rough opening, support and fasten the perimeter, and detail the exterior joint so water drains away from the opening and onto the exterior wall.
How is a crawl space kept ventilated through the foundation wall?
Foundation vents provide ventilation through foundation or crawl-space walls to help control heat and moisture below the building.
