Note: While DUROVENT is the best foam rafter vent available, we recommend homeowners use PROVENT to make their attic ventilation project much easier.
DUROVENT is recommended for new construction, while PROVENT is recommended for
insulating existing attic space.
Why ventilate your attic?
Installing attic ventilation channels between the rafters of trusses provides an unobstructed air channel through the insulation. Without attic ventilation channels air cannot flow freely from the soffit to the exhaust vents. Poor airflow reduces insulation efficiencies and accelerates problems due to moisture.
How many ventilation channels?
One ventilation channel per rafter or truss cavity is recommended
1. Place Durovent ventilation channel over top plate.
2. Secure Durovent ventilation channel to roof deck with staples.
3. Install attic insulation tight against ventilation channel.
