Smart Vent Foundation Flood Vents are ICC-ES Certified and FEMA Accepted.

Entering flood water lifts the patented internal floats which unlatch and allow the door to rotate open. Our Insulated stacker model provides 400 sq ft of flood coverage while its insulated core makes it perfect for garages and air conditioned spaces. Made of T316L Marine Grade Stainless Steel, Smart Vent Flood Vents are strong, durable and can handle anything Mother Nature throws at it.
