Engineered Flood Vent - What Are They?

Engineered flood vents have a characteristic that differ from non-engineered flood vents. They are designed and certified by a registered design professional as meeting certain performance characteristics described in FEMA TB 1 / August 2008. Engineered flood vents may be equipped with screens, louvers, valves, or other coverings or devices provided that they permit the automatic entry and exit of floodwaters. The advantage of an engineered flood vent over a non-engineered vent is it takes fewer engineered flood vents to meet NFIP’s requirements.
