<p>PROBLEM TO BE SOLVED: To provide a method of manufacturing a lightweight composite building material excellent in heat insulating properties, sound insulating properties, and fireproof and fire-resistant performance.SOLUTION: In a method of manufacturing a composite building material having a core material between a pair of base materials, the core material is formed by spreading inorganic foamed particles with an average particle diameter of 1 mm or more all over the one base material, subsequently applying a resin foam material liquid to a surface thereof, and foaming and hardening it. Preferably, the inorganic foamed particle has an interconnected cell.</p> |
