We installed the roof of Mt. NEXAN in the outer balcony space and created a sunroom space where you can live while passing through the living room space. A folding door with a window is installed on one side and the front to create a more open view of the outside from the inside.

When the folding door is folded to open the space, ventilation proceeds with fast air circulation and creates a wider space effect with an open view. In addition, it is difficult to use it because it is a balcony space created as an external space in the hot summer or cold winter, on other rainy and snowy days, and on windy days due to the clear temperature difference. However, with the NEXAN roof, the folding door construction has made it possible to adjust and use it at any time.

Folzen Korea's sole patent, the rack gear handle, allows easy and light opening and closing operation without the need for a separate auxiliary handle. Our family's cozy space has a sufficient interior effect, as well as high airtightness and airtightness when all of them are closed, so the quality of life has been improved as a comfortable living space with high insulation, soundproofing, and windproof functions.
