Most apartment verandas and living room middle doors use the same mirror windows as the image above. A sliding window is a window constructed with one or two fixed fixed and sliding windows.
However, due to the fixed fix window, even if one or two sliding windows are opened, the access space is limited, which is less space utilization than folding doors with a large opening and closing rate.

These days, where the use of space in the veranda is becoming endless unlike before, more and more people are enjoying relaxation or healing time by decorating various spaces such as study space, hobby space, home cafe, and house plant raising.

As shown in the picture, you can feel the effect of space expansion and separation on the opening and closing of the folding door with an opening rate of more than 90% of the folding door. You can use the space by opening or closing all folding doors, but you can use the space more conveniently by adjusting the opening and closing rate as much as you want.​
