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.

Based on 1/300 Rule
Total Attic Square Footage	Recommended Length of Cobra^® Snow Country™ Exhaust Vent (Feet)	Minimum Exhaust Ventilation (Net Free Area in Sq. In.)
1600	22	396
1900	26	468
2200	30	540
2500	34	614
2800	38	684
3100	42	756
3400	46	828

Cobra^® Snow Country™ Exhaust Vent has 18.0 sq. in./linear ft. of net free ventilating area.

NOTE: Always have a balanced ventilation system. In no case should the amount of exhaust ventilation at the ridge exceed the amount of soffit ventilation.
