Folding doors that can be expanded without having to expand the veranda! The window with the highest opening and closing rate!

It is a highly preferred folding door for many people who are about to move into the apartment. Among them, veranda folding doors are under construction the most. As you can see, the veranda space is more useful and can be used in a variety of ways with a wide opening and closing rate.

If you expand the veranda, you can use the space wide and diverse without installing a folding door. However, it is inconvenient to live because the outside temperature flows into the room with one shot.

Thus, while opening and closing the folding door, it is a window where you can freely select and use the space separated from the expanded space.
