To solve the problem in which a 3 mm thick, ultra-thin insulation material utilizing aerogel, the first of the technologies supporting this invention, is an excellent material that exhibits high thermal insulation effect upon installation in building walls, ceilings, or floors even when used alone, yet its limited strength restricted its applications.SOLUTION: By sandwiching an aerogel insulation material, whose limited strength previously restricted its applications, between two layers of reinforced corrugated cardboard to form a plywood material, strength, which had been the biggest challenge, is enhanced. Furthermore, combining the inherent properties of aerogel and reinforced corrugated cardboard creates a synergistic effect. This not only further strengthens thermal insulation but also, while maintaining lightweight characteristics, provides soundproofing, moisture resistance, shock absorption, fire resistance, and fireproofing, etc. This dramatically increases applicability and versatility as a material.SELECTED DRAWING: Figure 1
