IN-Vent is an on-the-rooftop intake vent for when you can't put ventilation in the soffits or overhangs. Now, IN-Vent offers 10 square inches of Net Free Vent Area per lineal foot, the highest NFVA of any shingle-over intake vent on the market.
With 10" NFVA, IN-Vent stands head and shoulders above the competition with more than three times the amount of actual airflow than SmartVent.
