The folding door construction sites in the residence (apartment) are located in various places, including the front door, the main bedroom window, the multi-purpose room door, and the kitchen window, but the most of them are the veranda and living room doors. In the case of veranda folding doors, the space can only be used separately from the veranda and living room with the fixed glass of the existing misso window.

Residents who didn't like it, use a larger living room by expanding the veranda, and in that case, environmental factors such as condensation, external wind, and temperature enter the room, which makes the room temperature lower in the winter and the summer.

If you build a folding door instead of a veranda extension, you can expand and separate the veranda space at the same time, double-blocking noise and temperature, which greatly helps you feel the cooling and heating costs in the summer and winter, and even the interior of the house.

This construction site has constructed a total of 5 folding doors with veranda folding doors. Four of them are folding doors, and one additional handle is made so that it can be used as an entrance door. Therefore, even when the folding door is opened and closed, one folding door can be used as the entrance door for convenient passage.

In addition, the middle door of the multi-purpose room is made of MissK glass, which has a translucent effect, reducing frustration rather than opaque, and increasing safety by making it with a handle that can be used as a sigon device.
