PROBLEM TO BE SOLVED: To provide a method for producing glass fiber-reinforced rigid polyurethane foam which is small in surface unevenness and reduced in cutting loss to be a waste when cut into a panel in a prescribed shape. SOLUTION: The method for producing the glass fiber-reinforced rigid polyurethane foam comprises an undersurface material feeding process for feeding an undersurface material 11L, a glass fiber mat feeding process for feeding a glass fiber mat 20 on the undersurface material 11L, a network sheet feeding process for feeding a network sheet 41 on the glass fiber mat 20, a stock solution feeding process for feeding a rigid polyurethane foam foaming stock solution 5 to the glass fiber mat 20 having the network sheet 41, and a foaming process in which the rigid polyurethane foam foaming stock solution 5 is reacted/foamed into the glass fiber-reinforced rigid polyurethane foam B.
