Upgrade soffit ventilation in a fiber-cement exterior assembly with this 7.5-inch by 22-inch Vulcan vent. The galvanized-steel body combines ember-resistant screening with a heat-reactive matrix designed to help reduce ember and flame intrusion while maintaining the airflow an attic needs. Its 3/8-inch recessed fiber-cement flange supports a cleaner integration with compatible siding and soffit details, and its 119-square-inch NFVA can help reduce the number of vents needed to meet a ventilation plan. A strong choice for wildfire-conscious new construction or replacement work. Confirm opening size, code requirements and installation details before ordering.
