Windows refers to various windows or doors installed at entrances to block the interior of the building from the outside, and are classified into wooden windows, plastic windows, and metal windows according to the materials they make.

The window is largely formed of an outer frame and includes a window frame frame having rails on the upper and lower inner circumferential surfaces, and at least one pair of windows that are slidably coupled to the rail through a roller to open and close.

Looking at the opening and closing process of the window of the secretary, which is a typical type of window, is as follows. First, when the user slides in the direction of closing the window pair while holding the handle of the window pair, the roller mounted on the lower part of the window pair rotates along the rail on the window frame frame, and accordingly, the window pair gradually moves on the opposite side. The closing operation is ended by approaching the window frame frame and finally stopping by contacting the window frame frame.

Most of these windows include a heat insulation reinforcing member or a windbreak member to improve heat insulation and airtightness. However, conventional heat insulation reinforcing members or windbreak members do not have sufficient heat insulation and airtightness improvement, and the aesthetics are not neat by using pieces to fix them to the window frame frame, and they are installed on the inner and outer walls and rails to limit the use of windows and doors. There is a drawback to it.

Accordingly, there is a demand for the development of a new window system that has excellent insulation and airtightness, has a neat appearance, and does not interfere with the use of windows.
