Balanced Ventilation Requirements
Balanced ventilation requires an equal amount of intake ventilation and exhaust ventilation. GAF recommends, at a minimum, providing 1 square foot of Net Free Ventilation for every 300 square feet of attic floor space. Consult local building codes for specific ventilation requirements in your area.
- Calculate the total square footage of the attic floor area (round up to the next highest number). This number will determine the minimum total linear feet of Cobra® Snow Country Exhaust Vent that is needed.
- Find the appropriate amount of Cobra® Snow Country Exhaust Vent and minimum intake ventilation that corresponds to the total attic square footage.
