く表面の機械的強度も小さい等の問題がある。(Prior technology) Conventional lightweight, heat-insulating siding is made by combining synthetic resin foam on the back side of an inorganic substrate, but it has problems in terms of flame retardancy and the generation of toxic gas when exposed to flames. Although there are some products in which a lightweight inorganic material such as pearlite is composited on the back side, the specific gravity and water absorption are large, and there is also the problem that pearlite tends to turn into powder. Furthermore, there are also sliced chemically foamed lightweight cements such as ALC, which have a light specific gravity and good insulation properties, but due to the nature of the foaming process, they are continuously foamed, so they have high water absorption and are resistant to freezing and thawing in cold regions. There are also problems such as low resistance to water and low mechanical strength of the surface.

Polystyrene balloons 16 having a diameter of 0.1 to 3 mm as shown in FIG. 8 are formed in a dispersed manner. If the expansion ratio of the expanded polystyrene beads 15 is 100 times or more or if the diameter of the polystyrene balloon 16 is 3 mm or more, they will float on the heat insulating material composition, making uniform dispersion difficult. Further, if the expanded polystyrene beads 15 are 20 parts by weight or more or the diameter of the balloon 16 is 0.1 mm or less, the insulation composition slurry will be insufficient. The addition of the acrylic resin emulsion imparts water resistance to the heat insulating material 13, and the addition of the short fibers 17 provides the heat insulating material 13 with mechanical strength.
