Smart Vent Insulated Foundation Flood Vent 1540-520 | FEMA & ICC-ES Certified, 16x8 Stainless Steel

Overview

Smart Vent Insulated Foundation Flood Vents deliver purpose-built flood protection with a focus on reliability and straightforward installation. Each vent is FEMA compliant and carries ICC-ES certification (ESR-2074), providing up to 200 sq ft of flood protection per vent when installed following the guidelines. In practice, this means a measured response to rising water, as water can move through the vent to equalize pressure while the structure remains protected.

Bi-directional venting is a core feature: water can enter and exit as needed, helping relieve hydrostatic pressure that can otherwise push against foundation walls. The insulated version adds a dedicated core and weather stripping, aiming to keep interior spaces a bit more climate-stable when exterior conditions shift.

Engineering you can count on

Durability is central to the SMART VENT design. The vents are crafted from Marine Grade Stainless Steel (T316L), a material known for resisting corrosion in coastal and chemically challenging environments. Made in the United States, these vents are built to withstand the realities of outdoor use while maintaining a consistent performance over time.

For the insulated model, the combination of an insulated core and weather stripping supports a tighter interior envelope without compromising the essential flood-relief function. The surface-mount installation approach keeps the project manageable, and the Flood Vent Sealing Kit is available to help finish the interior space with a tight seal.

Installation and everyday benefits

• Surface-mounted installation with compatible adhesive and optional sealing kit for a tight interior finish
• Bi-directional airflow reduces hydrostatic pressure while maintaining floodwater movement
• Corrosion-resistant stainless steel construction supports long-term durability
• Compact 16" x 8" footprint suitable for foundations and crawlspaces
• FEMA compliance and ICC-ES ESR-2074 certification provide a tested, code-based solution

When installed correctly, this model offers a practical approach to flood risk management and may align with insurer expectations for code-compliant protection. If you’re updating or retrofitting a foundation, this vent offers a scalable option that fits standard dimensions while maintaining a focus on performance and resilience.
