A window-type folding door has been installed inside the restaurant located inside the cathedral to connect the kitchen with the dining table. During the meal time, the window-type folding door is opened so that the prepared food can be delivered. After the meal time, the window-type folding door is closed to separate the dining room from the kitchen space.

The folding door frame color is also silver to match the silver color of the aluminium, so that no difference is felt. If it's a window-type folding door that's installed on the outside, you need to build a lower rail with an external containment method. The interior window folding doors, which do not directly impact external weather or environmental conditions, are built with the same lower rail system as conventional folding doors.

Aluminium (AL-6N01) is designed to smoothly open and close the rails in the form of high alloy and bearing rollers and safely designed to prevent the runner from leaving. Semi-automatic driving makes it easy to open and close, and the rubber gasket finish between the doors prevents hand injury.

As a kitchen and dining room where hygiene is the most important, the window-type folding door is closed to deliver a cleaner feeling.
