ABSTRACT:
Exterior louver apparatus includes a frame (11) with an oblique frame member (15) with a plurality of exterior louvers (19) having pivot pins in the ends with a universal-type joint (46, 47) in the oblique frame member supporting one end of the louver so that it remains free to pivot. Each louver has a flexible flap-like edge extension (36) that is preloaded against a landing surface (22c) to prevent slapping of adjacent louvers under wind conditions. Each louver has both high strength and high heat insulating properties. A louver control includes a gear box (55) inside one corner of the frame which prevents turning of the louvers from the outside. A linkage for an end louver turns it back to prevent water from entering the louver apparatus.
