Flood Flaps Sealed Series flood vents are perfect for structures located in floodplains that desire conditioned space or an encapsulated crawlspaces. 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 will give to the pressure of flood water 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 provide a tight seal (watch a video and see for yourself) to keep enclosures protected from exterior climate air and insects. Superior Performance.

As flood waters rise, hydrostatic pressure builds around the home’s foundation. Flood Flaps® patented grill and rubber flaps give way to the pressure of the flood waters, allowing water to enter or exit the enclosed area as necessary.
Unlike other flood vents or traditional air vents, our collapsing components allow yard debris and/ or trash (up to 5.75”) to pass through as well.
This is extremely important. As flood waters tend to rise rapidly, clogged flood vents or traditional air vents will often clog with debris and trash, thus preventing water from entering the enclosed area and subjecting it to potential collapse.
When not subjected to rising water, it takes roughly 15 lbs. of pressure to force the grill out of its secured position.
Flood Flaps® flood vents help home owners maintain an esthetically pleasing look by protecting almost 4 times the amount of enclosed area that non-compliant vents protect. Each Flood Flaps® engineered flood vent covers 220 sq. ft. of enclosed area. Flood Flaps® flood vents are also stackable, another feature preserving the home’s elegance.
Flood Flaps® Sealed Series engineered flood vents can contribute toward achievement of credits for LEED-NC certification. Our flood vents use two rubber flaps to seal out air and moisture to ensure the enclosure remains conditioned and airtight. Make sure to specify and install Flood Flaps® Sealed Series engineered flood vents into residential or commercial new construction plans. Unlike other certified flood vents, our vents don’t require any rinsing, lubricating or other routine maintenance tasks. Flood Flaps® flood vents are easy to install and prevent debris and pests from accessing enclosed areas.
