The other thermal expansion fireproof material, that is, the second thermal expansion fireproof material 32b to the eleventh thermal expansion fireproof material 32k, is generally a thermal foam (foaming at about 200 ° C.). To start) is used.

Next, the action and effect of the sash 1 according to the present embodiment will be described.
As shown in FIG. 1, even if the resin profile 6 of the aluminum resin composite shoji 3 is burnt down in the event of a fire, the fourth thermal expansion fireproof material 32d provided in the lower frame 15 expands due to the heat of the fire and the lower stile. It comes into contact with the lower auxiliary plate 29 of 7 and closes the space between the lower stile 7 and the lower frame 15. As a result, it is possible to prevent outside air from entering the room from between the lower frame 7 and the lower frame 15 of the aluminum resin composite shoji 3 and blowing out flames in the room in the event of a fire.
Between the upper stile 5 and the upper frame 13 of the shoji, the third thermal expansion refractory material 32c expands and comes into contact with the upper auxiliary plate 31 to close the space between the upper stile 5 and the upper frame 13. Therefore, even between the upper stile 5 and the upper frame 13, it is possible to prevent outside air from entering the room or blowing out flames in the room from between them in the event of a fire.
