According to this embodiment, the following effects can be obtained. 1) On the lower frame 12, the first and second heat insulating members 12E, 12
Since the double heat-insulating line arranged in the indoor / outdoor direction of F is provided, the heat-insulating performance can be improved as compared with the conventional heat-insulating sash window having only a single heat-insulating line, and thereby the dew-proofing performance can also be improved. In particular, in the window frame 2, the heat insulation performance of the lower sash 12 which is the most important for improving the heat insulation performance and the dew protection performance of the sash window 1 is improved. The performance can be effectively improved.

2) Between the rails 18 and 19, the first
Since the heat insulating member 12E is interposed, even if the outdoor member 12A exposed to the outside is cooled by the outside air, the heat can be blocked by the first heat insulating member 12E to the intermediate member 12D in which the inner rail 19 is formed. Can be suppressed.

Even if 1 or the vertical frame 13 is cooled by the outside air, it is difficult to transfer heat to the indoor side end portions of the heat insulating covers 201, 205, 206, so that the occurrence of dew condensation can be suppressed.

5) The heat insulating cover 203 is the second heat insulating member 1.
Since the upper surface of 2F is covered, the second heat insulating member 12F is not exposed to the indoor side, and the heat insulating performance of the second heat insulating member 12F can be further improved and the designability can also be improved.
