PROBLEM TO BE SOLVED: To provide a fire resistive panel for a spandrel wall of a curtain wall which has dimensional stability under change in temperature, electric wave non-reflectivity, fire-resistance, lightweightness and large bending strength, and which is easy to manufacture. SOLUTION: The fire resistive panel for the spandrel wall of the curtain wall comprises magnesia cement based boards containing 75 to 94.5 weight percent of a magnesia cement, 0.5 to 5 weight percent of a reinforcing fibrous material, and 5 to 20 weight percent of a lightweight aggregate as main materials, and a phenol foam plate. The magnesia cement based boards are glued onto both faces of the phenol foam plate. Preferably, the reinforcing fibrous material is in a mesh-state and is embedded in both sides of the magnesia cement based boards. Further, the reinforcing fibrous material preferably comprises short fibers which are dispersed in the magnesia cement based boards substantially evenly. COPYRIGHT: (C)2005,JPO&NCIPI
