する。However, the above-mentioned conventional netted plate glass or wire-lined plate glass having a plate thickness of 6.8 ± 0.6 mm or 10 ± 0.9 mm has a large weight.
Or, since the plate thickness is large, various problems have been pointed out. That is, when the net-filled plate glass or the wire-filled plate glass is used for the pulling sash, labor is required to open and close the shoji screen.

であると破壊しにくいという不具合もある。Similarly, since the plate thickness is large, there is a drawback that the color of the glass becomes dark and the transparency is poor. In addition, when the double glazing is used, the whole plate thickness becomes large and it cannot be attached to a normal sash, and it is not easy to replace it with a conventional sash. Further, when breaking for an evacuation route in the event of a fire, there is a problem that it is difficult to break if the plate thickness is large.

It has been conventionally recognized that 6 mm or more is necessary, and it was considered that the above-mentioned problems should be accepted. In addition, since the net made of metal or the wire made of metal is uneven or wavy with respect to the thickness of the glass plate, the plate thickness is 6.8 ±
It could not be made smaller than 0.6 mm.

In, there is provided a net-filled plate glass or a wire-filled plate glass having a plate thickness of 3.0 to 5.5 mm. With the net-filled plate glass or the wire-filled plate glass having such a plate thickness, various problems due to the large weight or the large plate thickness can be solved. Further, the fire resistance is not inferior as described later.

る。According to the present invention, it is possible to make the thickness of the net-filled glass or the wire-filled glass smaller than the conventional thickness of 6.8 ± 0.6 mm. As a result, various problems such as net-filled glass or wire-filled glass can be obtained. When flat glass is used for the sliding sash, it requires labor to open and close the shoji screen, and since the plate thickness is large, the color of the glass becomes dark and the transparency is poor. Since it becomes large and can not be attached to a normal sash, it is not easy to replace it with a conventional sash, and when breaking for an evacuation route in the event of a fire, the problem that it is difficult to break if the plate thickness is large, etc. are solved. ,
It is also possible to expand the applications of net glass or wire glass.
