Let This makes it possible to obtain a fire-resistant insulation panel that can pass the JIS-A-1340 fire-resistant structure 1-hour test.
- the core material of the fireproof / heat insulating panel is formed so that the density is higher at the connection side end than in the center of the panel. This makes it a weak point for fireproof and insulating panels.
- the fire resistance of the connected parts will be greatly improved, and it will be possible to obtain a fire-resistant insulation panel that can pass the JIS-A-1304 fire-resistant structure 1-hour test.
- a fifth feature of the present invention is that the side surface of the core material of the surface material and / or the side surface of the core material of the back surface of the fireproof heat insulating panel is embossed.
- the unevenness due to this embossing makes anchors, strengthening the adhesion between the surface material and the back surface material and the core material, and also improving the mechanical strength of the fireproof and heat insulating panel, and distortion during molding of the front and back materials.
- the appearance can be suppressed and the appearance can be formed beautifully. Therefore, the mounting pitch to the body can be made longer and the workability can be improved.
- a sixth feature of the present invention is that a core layer of a fireproof / insulating panel is provided with a foam layer and / or a polyurethane foam layer.
- This fire foam layer and Z or polyurethane foam layer greatly improve the fire resistance and the overall strength of the heat insulation panel, make it difficult to be deformed by heat, and greatly improve the fire resistance of the joint part. It will be.

- a wooden skeleton material with a water content of about 15% is used to form a grid and put it in the core material. Buried.
- the mechanical strength of the core material itself is greatly improved, and moreover, efficient foaming can be achieved without the wooden skeleton material absorbing the condensed water during the reaction of the core material and inhibiting the reaction.
- the wooden skeleton will also control the humidity in the core material, and the change in shrinkage due to drying will be reduced.
- the wooden skeleton functions as a moisture-exhaust material (function of humidity control material).
