A heat-insulating bridging member provided with a heat insulating bridge member connecting the outdoor-side profile and the indoor-side profile, wherein a cross-sectional shape of the outdoor-side profile is a cross-section of the indoor-side profile. It is smaller than the shape.

In the present invention, when the cross-sectional shape of the outdoor shape is smaller than the cross-sectional shape of the indoor side shape, the outdoor shape expands due to a temperature difference between the indoor and outdoor, and the indoor side shape shrinks. Since the force with which the outdoor shape member expands is larger than the force with which the indoor shape member contracts, the indoor shape member can follow the expansion of the outdoor shape member. Thereby, it can prevent that an outdoor shape member warps.
In addition, because the cross-sectional shape of the outdoor shape is smaller than the cross-sectional shape of the indoor shape, the cross-sectional shape of the indoor shape and the cross-sectional shape of the outdoor shape are the same. Compared to the case where the cross-sectional shape is larger than the cross-sectional shape of the indoor-side profile, the outdoor cold temperature is less likely to be transmitted to the indoor-side profile via the outdoor-side profile. Can be insulated and indoor condensation can be prevented.

Moreover, in the sash which concerns on this invention, it is preferable that the said outdoor shape is a smoke return part.
By adopting such a configuration, the difference in size between the cross-sectional shape of the outdoor shape that is the smoke return portion and the cross-sectional shape of the indoor side shape other than the smoke return portion can be increased. When the indoor side shape member expands due to a large temperature difference, the outdoor side shape member can be made to follow the expansion, and the indoor side shape member can be prevented from warping.

In the sash according to the present invention, a plurality of the heat insulating bridge members may be provided between the outdoor shape member and the indoor shape member.
By setting it as such a structure, since a heat insulation bridge material becomes a connection part of an outdoor shape and an indoor side shape, it can connect an outdoor shape and an indoor side shape reliably.

Moreover, in the sash which concerns on this invention, the said heat insulation bridge | bridging material is good also as a structure provided between the said outdoor side shape material and the said indoor side shape material which diagonally oppose with respect to a prospect direction.
With such a configuration, the difference between the cross-sectional shape of the outdoor shape and the cross-sectional shape of the indoor shape is large, and the outdoor shape and the indoor shape are in the expected direction. Even when the facing portions are small, the heat insulating bridge material can be provided if the outdoor shape and the indoor shape have a portion that is diagonally opposed to the prospective direction.

The sash according to the present invention is preferably a composite sash of aluminum and resin.
With such a configuration, even in a composite sash of aluminum and resin, it is possible to prevent the outdoor shape from warping and to efficiently insulate the interior and exterior of the summit interior, preventing indoor condensation. it can.

According to the present invention, when the cross-sectional shape of the outdoor-side profile is smaller than the cross-sectional shape of the indoor-side profile, the outdoor-side profile expands and the indoor-side profile contracts due to a temperature difference between the indoor and the outdoor. In addition, since the force with which the outdoor shape member expands is greater than the force with which the indoor shape member contracts, the indoor shape member can follow the expansion of the outdoor shape member. Thereby, it can prevent that an outdoor shape member warps.
In addition, because the cross-sectional shape of the outdoor shape is smaller than the cross-sectional shape of the indoor shape, the cross-sectional shape of the indoor shape and the cross-sectional shape of the outdoor shape are the same. Compared to the case where the cross-sectional shape is larger than the cross-sectional shape of the indoor-side profile, the outdoor cold temperature is less likely to be transmitted to the indoor-side profile via the outdoor-side profile. Can be insulated and indoor condensation can be prevented.
