Screens can be used very effectively for adding a character to the elevation of a building,apart from providing sunshade and ventilation.
There are absolutely endless ways to design and manufacture them, each made to suit a particular structure. And they need not be a fixed geometrical pattern. GFRC, precast concrete or even UHPC (Ultra High-Performance Concrete) can be used to manufacture very beautiful looking screens, even though the most basic screens that are in square patterns also look very elegant.
We generally try to make screen so that horizontal joints are avoided (screen extending from one floor to next floor level ) single elements can generally be made up to 3 meters in height, with connection details suitable for each site conditions.
