ABSTRACT:
A sliding window comprises a window frame composed of upper, lower, and first and second vertical frame members, to which indoor side and outdoor side sashes are mounted. A space continuous around the periphery of the window frame is formed to the outdoor side of the window frame. The space is provided with a port communicating with the outdoor atmosphere, thereby having a pressure equal to an atmospheric pressure. The window frame, the indoor side sash and the outdoor side sash have respectively heat insulating lines continuous around their respective peripheries. The indoor side sash is mounted to the window frame at the indoor side relative to the heat insulating line of the window frame, and the outdoor side sash is mounted to the window frame in such manner that the outdoor side portion relative to the heat insulating line of the outdoor side sash are positioned at the outdoor side relative to the heat insulating line of the window frame and the indoor side portion relative to the heat insulating line of the outdoor side sash is positioned at the indoor side relative to the heat insulating line of the window frame. When the indoor side sash and the outdoor side sash are closed, an air layer is formed at a mating portion between the indoor side sash and the outdoor side sash.
