Shop Flood Vents

Flood vents are permanent wall openings that allow floodwater to enter and exit an enclosed area automatically. They help equalize water pressure on foundation and enclosure walls, reducing the risk of structural damage during flooding.

Yes. All Flood Solutions flood vents are ICC-ES certified engineered openings. When properly installed, they meet FEMA and National Flood Insurance Program (NFIP) flood opening requirements. Visit our certifications page for evaluation reports and product documentation.

Engineered flood vents have documented performance ratings that establish how much enclosed area each vent can serve. Non-engineered openings are sized by their net open area. Flood Solutions vents have engineered coverage ratings, so use the selected model’s documentation when determining how many vents your project requires.

The number depends on the enclosed area and your selected vent’s engineered coverage rating. Flood Solutions models provide coverage ranging from 97 to 191 square feet per vent. Each separate enclosure needs at least two flood openings on different exterior walls, with additional vents as required for coverage. Follow our installation requirements for placement and sizing.

Yes. Flood Solutions flood vents stay open year-round, allowing continuous fresh air circulation to help keep crawl spaces dry. Their grille design also helps keep insects and rodents out.

Our flood vents are made in the USA from heavy-duty aluminum that will not rust or rot. They come unfinished and can be painted to match surrounding surfaces or installed unpainted.

Do not install a cover that blocks the automatic entry or exit of floodwater. A solid cover that must be removed by hand before a flood prevents the vent from functioning as required. Flood Solutions vents are designed to remain open.
