Folding doors and fix windows were installed in one part of the wide office to expand and separate the space with a wide opening and closing rate to increase space utilization. A fixed and non-open window, Fix Window, was built lightly and a folding door was installed inside it, giving space diversity from one space to two spaces or one space.

We constructed 8 pairs of fix windows, 4 pairs of folding doors, and 1 pair of folding doors. The glass in the fix window has a translucent effect on the fog sheet and partially translucent effect so that it can be used as a private space.

Since the folding door is installed in a large office divided by a fixed window, it can be used as one space without any difference as when it was divided into two spaces. If you separate the space by setting up an opaque light, the office looks narrower and even stuffy. Partial translucent windows and transparent windows allow outside sunlight to appear brighter throughout the office, and even lighting is possible.

In addition, even the hot heat and cold draft outside, which are difficult to block with one glass, can be blocked once more through the fix window to prevent inflow into the room, maintaining the proper temperature of the room. In particular, the role of protecting the interior with noise and draft around it is continuing to be installed in business and residential spaces in addition to offices.
