Lomanco C416-W Cornice Vent 16x4 Inches White Aluminum

Product Description

The LOMANCO C416-W is a 16-inch by 4-inch white aluminum cornice vent designed for under-eave installation in residential attic ventilation systems. It functions as an intake vent, drawing fresh air into the attic space to work in tandem with exhaust ventilators mounted at the ridge or roof deck. The eyebrow-styled louvers direct airflow while shedding water and debris. Construction is heavy-duty aluminum, and an attached insect screen prevents pest entry without restricting airflow. Installation is typically performed by roofing contractors or general contractors during new construction or re-roofing projects.

The C416-W is suited for residential applications where soffit or eave space accommodates a 16-inch by 4-inch vent opening. It is intended as a companion product for all types of exhaust ventilators, making it appropriate for balanced attic ventilation systems that pair intake vents with ridge vents, power ventilators, or turbine-style exhausts. The white finish integrates cleanly with standard painted soffits and eave trim. Sold individually, with a package quantity of 12 units per case for trade orders.

Installation Notes

Installation is typically performed by a roofing contractor or carpenter and involves cutting a matching opening in the soffit or eave board to match the 16-inch by 4-inch vent dimensions. Secure the vent with appropriate exterior fasteners and verify the insect screen is fully seated before closing up the assembly. Follow local building codes for required net free ventilation area ratios, which commonly reference a 1-to-150 or 1-to-300 attic floor-to-vent-area standard. Ensure no insulation blocks the vent opening from the attic side after installation.
