Why glass balcony ? Areas such as balconies, terraces and winter gardens in the buildings needed to be closed in order to prevent them from being affected by adverse weather conditions. At this stage, options such as aluminum and pvc joinery were used. These solutions change the current situation of the area and turn it into a comfortable living space, but cause the field of view to be restricted and the aesthetic appearance of the building to change. Today, the development of glass balcony systems and the increase in their usage areas have created alternative solutions to these systems. However, although the main purpose of the glass balcony systems is to protect the area from external factors, they cannot provide the opportunities provided by the joinery systems. As Lockwin brand, we have taken these factors into consideration and designed systems that will provide maximum panoramic view with minimum profile detail by making changes on the design details of the systems. Lockwin moving systems; It consists of sliding system, folding glass balcony and automatic vertical glass system (guillotine) series.
