Thermal expansion coefficient in the temperature range of 30 to 380°C is 10x
A transparent crystallized glass plate with a temperature of 10-7/℃ or less is fitted into a recess formed inside the periphery of the frame, and is heated for 60 minutes and subjected to shock according to the refractory heating curve specified in Ministry of Construction Notification No. 1125.

。The reason why the thermal expansion coefficient of the transparent crystallized glass plate of the present invention is limited as described above is that the thermal expansion coefficient is 10×1.
If a crystallized glass plate with a temperature of 0-7/℃ or higher is used, the heat during a fire will generate large stress on the glass plate, causing cracks and cracks, and as a result, the fire door will not be able to block out flames and smoke. This is because mechanical strength is significantly reduced.

A sealing material that does not ignite and does not harden when heated is suitable, and preferably a combination of inorganic fiber and sealing material is used. Note that when only inorganic fibers are used, there is a risk that they may fall off during use, so it is preferable to cover the surface layer with an elastic sealing material.
