Abstract
A flood and combustion air vent includes a louvered panel supporting a rodent screen for placement across an opening in a wall or door of an enclosed space in a building. The apertures in the louvered panel and rodent screen are sized to accommodate ingress and egress of flood water at a rate of water flow sufficient to prevent destructive hydrostatic forces from acting upon either the exterior or interior surfaces of the wall or door. Additionally, the rodent screen will prevent intrusion of rodents, vermin and reptiles into the enclosed space.
