The Bi-Directional vent feature allows water to flow freely both in and out, relieving hydrostatic pressure and protecting your foundation from flood damage. Entering flood water lifts the patented internal floats which unlatch and allow the door to rotate open. Our Dual Function Engineered Flood Vent provides up to 200 ft. of flood protection and allows for natural air flow through your crawlspace or enclosed area that needs ventilation. Our Insulated model provides the same flood coverage while its insulated core makes it perfect for garages and air conditioned spaces. Made of T316L Marine Grade Stainless Steel. - Dual Function Flood Vents contain a bimetal coil that automatically opens and closes the ventilation louvers with temperature change, remaining closed at 35˚F and fully open at 75˚F. - Smart Vent Foundation Flood Vents are FEMA Compliant and ICC-ES Certified (ESR-2074) for 200 sq. ft. of flood protection per vent. - The Smart Vent product line is constructed out of Marine Grade Stainless Steel and is 100% made in the United States. T316L Stainless Steel is renowned for its ability to withstand usage in harsh marine and chemical environments, ensuring that our products will handle everything Mother Nature throws at them. - The lower flood risk associated with the proper installation of Smart Vents can lead to a much lower insurance premium for you home. Save money and protect your property with engineered flood vents. ## Images ![Dual Function, Engineered Foundation Flood Vent, FEMA Compliant and ICC-ES Certified Model 1540-510… (Stainless Steel) - Image 1](https://m.media-amazon.com/images/I/81EqZ-1WpXL.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Great Product! *by K***R on Reviewed in the United States on February 5, 2023* Good quality, and easy to install! ### ⭐⭐⭐⭐ 4.0 out of 5 stars Best on the market but expensive *by P***B on Reviewed in the United States on April 13, 2021* Best flood vent on the market, but expensive. The combination vent/flood vent means less vents you need to install overall. Stainless is forever, install and done. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Building inspector was very pleased with these! *by P***N on Reviewed in the United States on July 2, 2015* These were recommended by a friend who use to be a building inspector. I installed two which was code required on my 14x24 shed. On the final inspection the current inspector was very impressed with these and said they would have more then necessary flow unlike the plastic ones he usually sees and has to fail based on inadequate flow. I was just glad to pass the inspection. These were not hard to frame out and install and I can always close them off inside right over the framing I put in. If you gotta install flow throughs these are the best. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.lk/products/21227762-dual-function-engineered-foundation-flood-vent-fema-compliant-and-icc](https://www.desertcart.lk/products/21227762-dual-function-engineered-foundation-flood-vent-fema-compliant-and-icc) --- *Product available on Desertcart Sri Lanka* *Store origin: LK* *Last updated: 2026-05-20*
