A window-type folding door has been constructed on the second floor of the new private house. The folding doors are installed in both the front and the side so you can enjoy the outdoor scenery with a wide opening. In addition, it can be opened and closed easily with semi-automatic operation. Unlike ordinary window folding door lower rails, the lower rail is constructed to prevent rainwater from entering the room on rainy days.

We proceeded with a black frame that goes well with wood and a blue+transparent 16T double-glazed glass.

With more than 90% of the opening, you can quickly ventilate the dust and murky air that can be generated indoors and maintain a pleasant indoor environment.
When closing the door with a rubber gasket finish between doors, double engagement prevents hot and cold temperatures from entering the room, increasing the insulation effect.

Looking from the outside, the folding door made the house look even nicer.
