Sized to fit a typical concrete block opening.

Proper venting of homes with a crawl space foundation has long been a challenge for homeowners.

Proper crawl space foundation ventilation prevents the buildup of mold and moisture.

Most homes have fixed vents that limit airflow in warmer weather and that do not seal well or at all in winter.

Our vent provides ventilation, and the insulated panel can be installed during the heating season. This allows you to add some heat into your crawlspace foundation to keep your pipes and your floors from freezing.

The vent is insulated and serviced from the outside, so there is no need to enter the crawlspace foundation.

Our vent can be retrofitted to existing homes, is easily serviced, easily insulated, and easily adapted to meet the changing seasons.

The dual-mode flexibility of our Crawl Space Foundation Vent Cover provides maximum ventilation in warm months and maximum insulation in cold months.

Nearly 19 million homes in the United States have crawl space foundations where homeowners face these ventilation dilemmas every year.

This vent is the only product available that help homeowners solve these problems.

Faceplate is made of heavy duty, durable, gray color ABS plastic. No painting needed (but can be painted if desired). Stainless steel screen is rodent proof.
