The invention relates to a method of insulating a furnace with the aid of free-standing elements of insulating material whose volume decreases at high temperatures. The invention is characterised in that the insulating elements are wedge-shaped and placed so that the wedges point inwards towards the heated volume of the furnace. The insulating elements are caused to move in the direction of the wedges as the volume of the insulating elements decreases, such as to cause said elements to approach each other in a direction at right angles to the direction of movement of said elements, therewith maintaining the imperviousness of the furnace insulation during the heating process. The invention also relates to an arrangement. |
