Expert Verdict — Reviewed by the SuperArbor Pro Desk
Cornice vents are a straightforward way to add soffit intake where full soffit vent strips are not practical, especially on older homes with wide cornices. Choose the 7 in. x 15 in. size when you need more intake area per opening and fewer cut-ins. Always verify that intake net free area equals or exceeds exhaust net free area to keep the attic breathing properly.
Cutting vent openings into cornice or fascia material can produce sharp aluminum edges; wear gloves and eye protection, and follow local building codes.
Choose your Lomanco aluminum cornice vent size and color and complete your intake ventilation.
