Glass balcony systems are based on the principle of opening all the windows by folding them to the appropriate corners of the balcony, by moving the windows in aluminum rails. Considering that city life is getting more and more tiring and stressful today, balconies, which create a space of freedom for people in their homes, gain even more importance. In the past, balconies were made of PVC, aluminum joinery etc. It was closed with materials and turned into a completely closed environment. However, the balconies covered with these materials would lose their balcony function and would be no different from any other room in the house. With the meeting of the glass balcony systems with the consumers, this situation has disappeared. Thanks to balcony glazing systems, balconies have gained the flexibility to open when desired by gathering the glasses to one side, and to close when desired by closing the windows, without losing their original functions. Thus, balconies became “free living spaces” for users.
