Abstract
PURPOSE: To efficiently form recessed and protruded pattern of sufficient solid appearance, by hotpressing a sheathing insulation board and by forming the pattern on the board as board treating asphalt is fluid.
CONSTITUTION: While or after a sheathing insulation board is hotpressed, this board is treated with asphalt. A recessed and protruded pattern is made on the board as the asphalt is fluid. For example, a synthetic resin paint is coated on the surface of a sheathing insulation board complying with the JISA5,905 standard and is dried. The board is then inserted in between metal molds so that the board is hotpressed at a temperature of 20°C under pressure of 20W100kg/cm2 for 5W10 seconds. As a result, blown asphalt in the board is molten and fluidized and a recessed and protruded pattern corresponding to that on the surface of the upper metal mold is made on the board.
