Fypon E-Vent Systems provide attic ventilation while maintaining the architectural integrity of a home's exterior. Each E-Vent System features a corrosion-resistant screen that helps keep insects out while allowing for maximum airflow. In new construction, an E-Vent may eliminate the need to extend the soffit overhang, as well as the associated materials, accessories and labor required for installation. It may also downsize truss tails, thus reducing the amount of shingles and roof sheathing.
