Description

[Detailed Description of the Invention] The present invention relates to a heat insulating device for a bay window made of aluminum sash.

Since the aluminum that makes up the aluminum sash has good thermal conductivity, the difference in temperature between the indoor and outdoor sides can cause condensation on the indoor sash frame, and outside air can also pass through the sash frame and enter the indoor side. make it difficult to maintain the temperature or inhibit the temperature rise. This phenomenon is particularly noticeable in cold regions.

In order to solve these problems, conventionally, so-called double-paned windows have been created in which the aluminum sash has a double structure, and the outdoor aluminum sash is connected to the indoor aluminum sash through a heat insulating material to block the conduction of outside air. Many methods have been proposed and put into practical use.

However, aluminum sashes with such a structure, especially for bay windows, have the disadvantage that they are not only complex and troublesome to install on buildings, but also much more expensive than ordinary aluminum sashes.

The present invention was devised in view of the above-mentioned conventional problems, and aims to provide an insulated bay window that is simple in structure, easy to install in a building, and inexpensive.

In order to achieve the above-mentioned object, the insulating bay window according to the present invention is a frame material fitted into an opening of a building, and includes at least two frames protruding toward the indoor side of the building.
