Protect your home from flood damage without sacrificing energy efficiency with the Smart Vent® Insulated Flood Vent for masonry walls. Designed to meet flood code requirements, this engineered flood vent automatically allows floodwaters to flow through enclosed spaces, helping reduce damaging hydrostatic pressure during flooding events. Its insulated design also helps minimize air leakage and improve thermal performance, making it an ideal solution for conditioned crawl spaces, basements, and flood-prone residential construction.
