SmartVent allows you to complete your ventilation by using an off-peak application which maintains the integrity of the unit. To provide perfect balance in your ventilation system SmartVent should be used as both intake and exhaust providing an optimum 9NFA/ft on each side.

How to use SmartVent on a Dormer Peak

Using normal soffit vents or DCI’s revolutionary SmartVent system, cooler air enters the attic at the soffit level and is drawn up and out of the SmartVent vent acting as an exhaust.   SmartVent’s single side venting creates excellent “negative air pressure” causing hot attic air to be literally pulled out of the structure that has a dormer peak. Use it on low slope dormer roofs with rubber or rolled roofing applied over the vent to seal.
