Adjustable perforated slats in Zurich Airport 
In the large window facing west in the expansion of Zurich Airport is provided a very effective and pleasant sun protection. This is a set of slats with horizontal rotation axis forming protective visors. In a west facing the slats are closed in the afternoon but the micro perforation allows a nice view to the outside and a more than adequate lighting. The protective surface does not reach the top of the window protected by flight. Or to the bottom for more open views from inside. The slats are moved by hydraulic bars located at one of its ends.
