Window elements can be subdivided according to numerous criteria into different groups depending on
the place of use, window shape , material, function or glazing.For the subdivision into window types, apart from the number and arrangement of the wings, as in single windows, multi-leaf windows or box windows, a distinction is also made according to the type of fixed frame and above all according to the mode of operation.
Depending on the opening type of the wings, a variety of window types with functions for tilting,
turning, swinging, flaps or turning are possible. Often also for your own comfort and for the best
possible ventilation several opening functions are combined in one window.
