Then, by providing the airtight / heat insulating material 7 (airtight / heat insulating main body 7b) so as to connect the aluminum portion of the lower stile 1b and the lower frame 3b while projecting upward, the heat insulating layer is enlarged while reducing the finding direction. It becomes possible to secure.

That is, in general, since the side wall portion 4 of the lower frame 3b of the aluminum resin composite sash is made of aluminum, cold air is transmitted to the portion of the resin angle material 11 on the side wall portion 4, and dew condensation is likely to occur on the upper surface of the angle chamber side. As a method for preventing this, it is conceivable to make the heat insulating layer as large as possible, but simply making the heat insulating layer large causes the inconvenience that the dimension in the finding direction becomes large.
On the other hand, in the airtight / heat insulating structure B of the present embodiment, the engagement base end portion 7a is attached downward, and the airtight / heat insulating main body portion 7b is projected upward from the upper end portion of the side wall portion 4. It is possible to secure a large heat insulating layer while reducing the direction.

Although one embodiment of the airtight / heat insulating structure of the sash window according to the present invention has been described above, the present invention is not limited to the above one embodiment and can be appropriately modified without departing from the spirit of the present invention. ..
