A method for manufacturing an insulation block, preferably an insulation plate, in which method the casting mould is adjusted to a desired size by moving at least one wall of the casting mould, the pre-expanded polystyrene, polypropylene or polyethylene beads are led to the casting mould, the pre-expanded polymer beads are steamed in the casting mould, and the formed finished insulation block is removed from the mould. In a method according to the invention at least one wall of the casting mould is moved during the steaming and/or during the cooling phase after the steaming. |

1. A method for manufacturing an insulation block, preferably an insulation plate, which insulation block comprises parallel first and second large planar surfaces and parallel first and second long side edges and parallel first and second short side edges perpendicular to the long side edges, delimiting the surfaces, characterized in that in the method
pre-expanded polymer beads are led to the casting mould, which polymer beads are selected from a group including polystyrene, polypropylene and polyethylene, and which casting mould comprises a lower wall, side walls and an upper wall, which walls together delimit the inner volume of the casting mould, pre-expanded polymer beads are steamed in the casting mould, the casting mould is adjusted to the desired size by moving at least one wall of the casting mould during the steaming and/or the during the cooling phase after the steaming, and the formed insulation block is removed from the mould. |
