Abstract: A louvre window system has an end clip (10) which is formed with at least one internal drainage channel (14) which can drain water through the end clip (10). A number of such clips can rotate between an open position and a closed position. The clips (10) are aligned when in the closed position which insures that water can drain from an upper clip through a lower clip. The clips (10) have a low friction design which enables a larger number of louvers to be rotated by a single handle (55) without placing too much load on the handle and on the louvre operating mechanism. A simple efficient louver operating mechanism (27; 37) is used to operate the end clips.

Abstract: A louvre window actuation system for a louvre window having a plurality of louvre blades and at least one operating bar associated with each of the louvre blades for movement thereof, the actuation system including a slidable handle movable between a closed condition in which the plurality of louvre blades are closed and a number of open conditions wherein the plurality of louvre blades are at least partially open wherein the slidable handle is operatively associated with the at least one operating bar to actuate the plurality of louvre blades.
