Why Bigger Isn’t Always Better – Efficiency in Vent Design.

Our 1-1/2” Joto-Vent provides efficient airflow with small, continuous openings at the top of the foundation – unlike typical vent boxes. But since building code require NFVA (Net Free Vent Area) comparisons, let’s look at the open area side by side.

Continuous Ventilation Means Smaller Openings and Efficient Venting.

Less is more. Joto-Vent System is a continuous ventilation means fewer openings and efficient venting, promoting faster drying and mold prevention.

Roughly 2.5 Pieces of Joto-Vent is equal to 1 piece of traditional vent box.
