Description

[Detailed Description of the Invention] The present invention is intended to provide a window having a novel configuration and having heat insulation and sound effects.

Hereinafter, details of one embodiment of the present invention will be described with reference to the drawings.

1 is the window to the merits of the case.

The structure is such that an outer window 3 made of aluminum sash or the like is provided on the outside of the window frame 2, and a multilayer window 4 is provided on the indoor side of the window frame.

This multilayer window consists of a first window unit 5, a second window unit 6, and a third window unit 7, which are stacked from the indoor side to the window outside side in the window frame, and the first window unit is the above-mentioned window unit. It is connected to the window frame so that it can be opened and closed by a screw 8, the second window is connected to the first window by a screw 9, and the third window is connected to the second window by a screw 10. ing.

On the inner peripheral surface of the window frame 2, there are window frame portions 5A and 6A of each single window of the multilayer window.

Step portions 2A and 2B corresponding to 7A are formed, and a backing material 11 is attached to the step portions.

Reference numeral 12 denotes an insert lock into which the first window unit through the third window unit are inserted.

13 is a heat insulating door provided between the outside window 3 and the window frame 2 so as to be openable and closable.

Reference numeral 14 denotes a wall body, and an outer wall 14C is provided on the outer surface of the glass wool 14A inside through a ventilation path 14B that communicates with the outside air, and an inner wall 14E is provided on the inner surface of the glass wool via a foamed heat insulating material 14D. is installed.

Since the present invention is constructed as described above, and the multilayer window is provided on the indoor side of the window frame, high heat insulation and strength can be ensured.

(In this case, a higher effect can be achieved if the glass portion of each single window is made of double-glazed glass.

) Also, each window that makes up this multi-layer window is constructed so that it can be opened and closed as a whole with respect to the window frame, so it can be used in the same way as a known double-glazed window, and each window can also be opened and closed individually. You can clean the condensation and dirt inside.
