How do I install proVent?
What are the specifications of proVent?
Slide proVent over top plate.
One proVent ventilation channel per rafter or truss cavity is recommended.
Without ventilation channels air cannot flow freely from the soffit to the exhaust vents.
Poor air flow reduces insulation efficiencies and accelerates problems due to moisture.
