FFWF05TF-W Flood Vent, 15-5/8 in W, 7-3/4 in H, 220 sq-ft Net Free Ventilating Area, Plastic, White

Flood Flaps Sealed Series flood vents are perfect for structures located in floodplains that require flood openings and desire a conditioned area or an encapsulated crawlspace. These models use two (2) rubber flaps to keep air from passing through the flood opening in non-flood situations, 365 days a year. In the case of a flood, the rubber flaps disengage as the pressure of flood waters rise, and allow water to enter or exit the flood opening. Energy efficient flood vents such as Flood Flaps Sealed Series models are even more important as states are adopting and enforcing the 2015 International Energy Conservation Code. Flood Flaps Sealed Series models are proven (visit our website flooodflaps.com to watch a video and see for yourself) to keep enclosures protected from exterior climate air, humidity, dust and insects.
