How Much Crawl Space Ventilation do I need? To determine how much crawl space ventilation you would need, follow this formula. First you need the cubic area of the crawl space. This can be calculated by multiplying the length x width x height of your crawl space. Divide this number by 15 to determine the minimum CFM (cubic feet per minute) necessary to fully ventilate the space in 15 minutes. Example: Your crawl space is 30' wide x 40' long x 3' high. Your crawl space is 3600 cubic feet. 3600 divided by 15 = 240 cfm needed from a crawl space ventilator Learn 4 Facts in 60 seconds about crawl space ventilation |
