PROBLEM TO BE SOLVED: To provide a panel material which enhances a heat reflexible function by giving a heat reflexing layer to a panel material which is a building material at a fabrication stage to improve cooling and heating efficiencies of buildings, in consideration of actual conditions where an improvement in cooling and heating efficiencies becomes a global problem in recent years by an increase of consciousness, strengthening regulations, etc. to enviromental problems, and developments of building materials having high heat shielding effects are desired.SOLUTION: There is provided a method of giving the heat reflexing layer to the panel material used as the building material. As a method for giving a heat ray reflexible layer on the surface of the panel for building, spherical metal oxide particles are adopted. |
