The "Ar-T" shading system consists of a frame of tubes, 0.8m long, 0.08m in diameter and 3mm thick. These twenty aluminum elements are placed along the top frame of the window, while another sixteen (8+8) cover both sides of the opening. The pipes have the possibility of extending up to 0.5m outside the 0.6m long cantilever. Two linear actuators push a guide rail onto which the tubes are attached. The second ones roll on specially designed roller wheels that embrace the curve of each cylinder.

The linear actuators move based on the azimuth of the sun forcing the tubes to take the proper formation in order to have the desired shading. For the azimuth values between 90o and 180o, the linacB stays permanently extended at 0.5m, while the linacA gradually extends until it reaches the maximum (0.5m) when the azimuth value is 180o. For values from 180o to 270o, linacA remains permanently extended at 0.5m, while linacB gradually recedes.

"Ar-T" offers shading at any time and day of the year without limiting visibility in order to maintain pleasant conditions in the working environment. Lastly, there is a manual override option, giving freedom to the user to choose if they want more or less shading any given time.
