Crawl Space Vent for 16 x 8 Foundation Openings

AdvantageVent crawlspace vents with thermal sealed glass are sure to provide energy efficiency, light transparency, and security that you seek. Thanks to the installed fans that turn on when the vent is open, it quickly exhausts moisture, stale air, and foul odor from your crawl space, preventing mold, mildew and wood rot. When closed during the cold winter, it completely seals the opening from the elements and keeps your floor warm while lowering your heating bills.
