PURPOSE: A window system is provided to minimize heat loss by completely blocking a path, through which air and noise can be transferred to the inside and outside of a second window frame. CONSTITUTION: A window system comprises soft contact members(110), side contact units(111) and a lift unit. The soft contact members are mounted on the upper and lower surfaces of a second window frame(101) formed on both sides of a guide groove(102). When the second window frame is opened and closed, the soft contact member are separated or make contact with the planar part of a first window frame, lifting. The side contact units are protruded from one side of the open end of the second window frame. When the second window frame is closed, the side contact units make tight contact with each other. When the second window frame is opened/closed, the lift unit makes the contact members lift. |
