Static Vents |
 |
Static vents (roof louvers, wall louvers and wind turbines) are inexpensive and popular with professional roofing contractors.
- According to federal guidelines, homes require 1 square foot of net free area (the total unobstructed area through which air can enter or exhaust a non-powered vent) for every 150 square feet of attic floor space. If balanced between intake and exhaust vents, the requirement is 1 square foot of net free area for every 300 square feet of attic floor space.
- Multiple roof vents are usually needed to provide the required net free area
- Must be spaced equally over roof to provide sufficient airflow along the entire roof sheathing
