Whenever possible, vents should be placed on all sides of the foundation. This will create an intake/exhaust system that delivers a steady flow of air. One vent should be installed for each 8 to 10 feet of foundation wall.
Most building codes require 1 square foot of open ventilation area for every 150 square feet of crawl space. Temp Vent Automatic Foundation Vents have 50 inches of net free area per vent. Therefore, you should install one vent for every 50 square feet of crawl space.
For crawl spaces with polyethylene installed, on 80-90% of the floor, the ventilation requirement changes to 1 square foot of ventilation for every 500 square feet of crawl space with a minimum of 4 vents installed to provide cross ventilation. For crawl spaces with polyethylene, install at least one vent for every 500 square feet of crawl space.
