PROBLEM TO BE SOLVED: To provide a manufacturing method for a glass fiber reinforced rigid polyurethane foam and a device therefor which easily corrects meandering before a glass fiber mat which is carried on an under surface material discharges/injects a foam liquid concentrate composition. SOLUTION: The manufacturing method comprises a glass fiber mat supply step of supplying a glass fiber mat 2 on the under surface material 1, a liquid concentrate supply step of supplying the rigid polyurethane foam liquid concentrate composition on the glass fiber mat 2 to be supplied, and an upper surface material supply step of supplying an upper material on the upper surface where the liquid concentrate is supplied. A meandering correction means 4 disposed between the glass fiber mat supply step and the liquid concentrate supply step feeds the glass fiber mat 2 downstream side, while correcting so that the glass fiber mat 2 supplied on the under surface material 1 shifts to the right and left in the width direction.
