Our crawl space vent minimizes potential wood decay to your home's foundation. This in turn will decrease wood rot in your crawl spaces and moisture problems in the living area of your home. In addition, the constant air circulation will vent other gases, such as those formed from residues in termite treatment, treated wood, and radon gases.

Crawl Space Vent Size Needed
To aid natural crawlspace ventilation, mechanical ventilation should exchange the crawlspace air at least four times an hour. To determine this, multiply the square footage of the crawlspace by the height to calculate the cubic feet then divide by 15 to determine the CFM needed to properly ventilate your crawl space.
Crawl Space Vent Formula
Length x width x height = total cubic feet of crawl space
Divide = total cubic feet of crawl space / 15 = CFM needed for proper foundation ventilation.
40' x 40' x 2' crawl space = 3200 cubic feet of area
divide 3200 cubic feet by 15 = 213 cubic feet per minute (cfm) of air flow needed to ventilate your crawl space
