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.

  1. 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® Ridge Runner® Exhaust Vent that is needed.
  2. Find the appropriate amount of Cobra® Ridge Runner® Exhaust Vent and minimum intake ventilation that corresponds to the total attic square footage.
