Overview an attic with balanced ventilation has undereave or soffit vents which allow fresh air into the attic. Hot air exhaust vents located at the peak of the roof allow hot air to escape.

Improper attic ventilation prevents the free flow of air from the soffit to the exhaust vents which reduces insulation efficiencies and accelerates moisture problems. Improper attic ventilation prevents the free flow of air from the soffit to the exhaust vents which reduces insulation efficiencies and accelerates moisture problems. Baffles placed in this area channel intake air into either the attic space or vent chutes and also prevent insulation from falling into the soffit and blocking airflow. Typically made from polyvinyl.

Provent may be installed prior to the soffit panel without fear of blow out. Rafter vents ensure the soffit vents are clear and there is a channel for outside air to move into the attic at the soffits and out through the gable or ridge vent.
