LOUVER ASSEMBLY HAVING IMPROVED WEATHERPROOFING AND AIR FLOW CHARACTERISTICS

摘要

The specification discloses a louver assembly for being mounted in a building and which includes a plurality of louver blades mounted in inclined positions sloping downwardly from back to front. Each of the louver blades includes an elongated open-topped trough having a rhomboidal cross section which extends along the lower edge of the louver blades. Each of the louver blades also includes a vertical rise along the mid-region thereof to allow water to freely drain down the blade into the trough while restraining water from flowing up the blade. A lip portion extends along the upper edge of each of the louver blades to prevent water from flowing over the upper edge of the blades. Apertures are defined at the ends of each of the troughs to allow water to drain therefrom. The louver assembly may be utilized in a conventional rectangular building louver or in a penthouse louver configuration.
