A method for manufacturing an insulating bar made from a thermoplastic plastics material whereof the base body has a corrugated structure comprises shaping the insulating bar as a blank having a substantially planar structure of the base body without raised portions and recesses but with the connection strips, cooling the blank to a temperature corresponding to the maximum long-term service temperature of the plastics material or lower, heating the base body to a forming temperature which, for crystalline plastics materials, is approximately 30&#xb0; C. below the crystallite melting point of the plastics material or higher, and for amorphous plastics materials, is approximately 30&#xb0; C. above the softening point or higher, forming the base body by a tool to produce the alternating raised portions and recesses, while retaining the geometry of the connection strips, and cooling the insulating bar to a temperature corresponding to the maximum long-term service temperature or lower.
