However, in the above-described heat insulating sash, since the heat insulating material of the lower frame is likely to receive direct sunlight and ultraviolet rays, the heat insulating material is likely to deteriorate. In addition, there is a problem that heat flows in and out from the outdoor-side exposed portion of the lower frame indoor-side profile. In order to solve such a problem, it is conceivable to cover the heat insulating material of the lower frame and the exposed outside surface of the indoor side profile with a cover material, but when the cover material is provided over the entire length of the lower frame. However, this causes a new problem that the cost is increased and the drainage property and the cleaning property on the lower frame are easily deteriorated.

The object of the present invention is to prevent the deterioration of the heat insulating bridge material in the lower frame due to ultraviolet rays and the like, and to prevent the heat from flowing in and out from the outdoor exposed surface of the indoor side profile, while reducing the cost and draining and cleaning. It is to provide a heat insulating sash that can be improved.

Further, the heat insulating sash of the invention according to claim 2 is such that at least the lower frame of the sash frame to which the inner and outer shoji are mounted is an inner shape member where the inner shoji is located and an outer side shape where the outer shoji is located. And the two sections are joined together via a heat insulating bridge material, and the upper surface portion of the heat insulating bridge material is connected to the heat insulating bridge material of the lower frame inner side shape member and the outdoor side shape member. It is formed on substantially the same surface and has low heat except the portion corresponding to the external shoji in the closed position so as to cover the heat insulating bridge material and the outdoor exposed portion of the indoor side member along the longitudinal direction on the lower frame. It is characterized in that a cover material made of a conductive material is detachably provided.

[0008]

In the heat insulating sash of the invention according to claim 1,
The cover material covers not only the entire length of the lower frame but also the outer exposed portion of the heat insulating bridge material and the indoor side member along the longitudinal direction of the lower frame, except for the portion corresponding to the shoji in the closed position. Since it is provided as described above, it is possible to prevent deterioration of the heat insulating bridge material in the lower frame due to ultraviolet rays and the like, and to prevent heat from entering and exiting from the outdoor surface exposed surface of the indoor side profile member,
