The present invention relates to a sliding window system having a structure for preventing drop and windbreaker, and is to provide a sliding window system including drop prevention plates. The drop prevention plates are inserted to upper and lower frame space portions of each side face of sliding windows constituting the sliding window system. An installation height is easily adjusted at a necessary withdrawal height through sliding with respect to waveform protrusions formed in window rail grooves. The drop prevention plate has high wind pressure resistance capable of preventing the window from dropping by supporting the window frame when strong wind pressure over a coupling force between a basic window and a window frame is applied. Normally, a sealing member coming in contact with the window frame comes in contact with a window frame face to block lateral air flow through a space portion between rails, thereby providing sealing and insulation abilities. The sliding window system according to the present invention comprises: a window frame; and one or more pairs of windows which includes rollers to be slid to left and right sides along rails formed in the window frame, wherein the window frame is provided with a sealing rail which is provided with a sealing member between the rail and the rail formed along the inner circumference, a window sill provided with a sealing member is formed on an indoor side to block airflow by coming in contact with the window face, and a drop prevention plate adjusted in a withdrawal height is installed in a vertical frame of each window to be supported by the window frame. |
