Picture 1Â shows some examples of typical window shapes and the proposed antiglare screen.

Picture 2Â shows how the shield move on a trapezoidal window. Three types of shield winding mechanism cassettes are available, depending on the size of the window:

The installation of shield collecting cassette can be done in two different ways: wall or ceiling mounting. Suitable brackets will be supplied also in case of inclinated wall.
The shading coefficient shows the amount of solar energy which ends up behind the arrangement, most often in the form of secondary radiation. The lower is the value, the more effective is the reflective arrangement. A high-coefficient foil can be used with good efficiency if the heat absorbed in the foil is ventilated away. All values are based on ASHRAE-testing methods. This means, among other things, that the foil is fitted to the inside of 4-millimetre thick neutral glass.

The cassettes, made of anodized or powder painted aluminum, are used to recover the film wrapped. Therefore they have a protective function in addition to mechanical characteristics necessary for the proper operation of the winding mechanism. Three different types of cassettes are used, depending on window maximum size.
027/S Cassette | |
---|---|
Window maximum size (Width x Height) | 1800 x 1500 |
Standard color | - anodized aluminium - painted powders (RAL 9010) |
Movement system | - by gravity guided by steel cables and manual cord winding - by lanyard and rewind spring - by tape and rewind spring |
058/S Cassette | |
---|---|
Window maximum size (Width x Height) | 2500 x 2500 |
Standard color | Anodized aluminium |
Movement system | - by lanyard and rewind spring - by the tape and rewind spring - by electric motor |
069/S Cassette | |
---|---|
Window maximum size (Width x Height) | 3600 x 3000 |
Standard color | - anodized aluminium - painted powders (RAL 9010) |
Movement system | - by lanyard and rewind spring - by the tape and rewind spring - by electric motor |
