Abstract
A louver has vertical blades arranged in a frame alternately in a staggered relation from front to back in a front and a rear row. The blades in at least the front row have a web oriented substantially perpendicularly to the plane of the frame and substantially parallel to the jambs, a pair of front flanges extending in opposite directions generally laterally from a front edge of the web, and a pair of rear flanges extending in opposite directions generally laterally from a rear edge of the web. The webs subdivide the air flow volume within the frame into flow channels, each of which is partially blocked laterally by the front flanges and the rear flanges of the blades of the front row. The blades of the rear row have flanges that block the portions of the channels between the extremities of the flanges of the blades of the front row. The flanges of the adjacent blades overlap so that there is no straight path through the flow channels along which air and water entrained in the air can pass perpendicularly to the plane of the frame and the air flows along a tortuous flow path of approximately constant area. The flanges are configured to control and trap water impinging on them.
