PROBLEM TO BE SOLVED: To provide a heat insulation panel capable of suppressing an increase in the number of components and in the production processes while effectively enhancing bending rigidity.SOLUTION: The heat insulation panel includes shells formed of a pair of rectangular metal plates and arranged on the surface and reverse sides, respectively, and a heat insulation layer formed of a resin foam and arranged therebetween, the heat insulation panel having a fitting protruded part on one side face and a fitting recessed part in the other opposite to one side face, the fitting protruded part of the heat insulation panel being insertable into the fitting recessed part of another heat insulation panel having the same structure. It further includes a resin foam heat insulation plate having a face bar formed of a material having a greater vertical elastic modulus than the resin foam and adhered onto at least one of the surface and reverse of the heat insulation layer formed of the resin foam, the resin foam heat insulation plate having no face bar existing in a region where the fitting protruded part is formed.SELECTED DRAWING: Figure 1 |
