Freedom Flood Vent - Bi-Directional Flood Vent, FEMA Compliant, ICC-ES Certified for 250 sq ft, Wall Mounted White - 16-inch wide x 8-inch high x 2-inch deep

Overview

The Freedom Flood Vent is a FEMA-compliant, engineered flood vent designed to cover up to 250 square feet per vent. It installs over foundation openings in crawl spaces, garages, and full-height enclosures, supporting wet floodproofing by allowing floodwaters to flow through the enclosure. By enabling bidirectional water movement, it helps relieve hydrostatic pressure on foundation walls during floods. Made in the USA and built to meet NFIP and building codes, this vent is designed to work as part of a broader flood-mitigation strategy without altering exterior aesthetics.

Key benefits

• Bi-directional flow relieves hydrostatic pressure on foundation walls, potentially reducing flood-stress on structures.
• Made in the USA and FEMA compliant, with NFIP and building code alignment for residential applications.
• ICC-ES certified (ESR-4332) for 250 sq ft of flood protection per vent, with rigorous testing for temperature ranges and impact resistance.
• Permanent door design adds security after a flood event, avoiding the need to replace a breakaway mechanism.
• Included winter shield maintains vent function while in use, and removable shielding allows natural ventilation when desired.

Installation and use

• Surface-mounted installation over the foundation opening, suitable for new construction or retrofits with compatible fasteners.
• Compatible with crawl spaces, garages, and full-height enclosures, expanding where airflow is needed.
• Retrofitting can be done with adhesive or equivalent fasteners to fit existing openings.
• Designed for straightforward installation without sacrificing structural considerations or exterior appearance.

Certifications and build quality

As a US-made product, the Freedom Flood Vent is FEMA compliant and NFIP-ready, with ICC-ES ESR-4332 certification. It meets ASTM D2565-99 and D6110-18 standards for impact and weathering, and is engineered to withstand temperature swings and weather exposure.

Real-world use cases

In flood-prone settings, these vents are intended to support wet floodproofing strategies by enabling automatic water entry and exit. While results vary by site, many homeowners view them as a practical component of risk-aware home maintenance, potentially contributing to more favorable insurance discussions when combined with other mitigation steps.
