It offers a different movement system compared to ordinary sunroof systems. All panels that can rotate around their own axis are opened and collected backwards, forming a fully open monolithic ceiling as in the glass ceiling. It is the only system that can perform both folding and collecting movements. You can enjoy the sun change and fresh air in the open air, meanwhile, you can easily use it in rainy weather in winter without being affected by the cold. It allows you to use your outdoor spaces in the most suitable form for all four seasons.
