In order to provide a spacer for insulating-glass units which, on the one hand, can be deformed by cold bending using conventional systems, but at the same time provides for the greatest possible level of thermal resistance, it is proposed that the spacer comprises a profile body which is made of a plastics material and has a substantially rectangular cross section with first and second side walls, which are arranged parallel to one another, and with an inner wall, which extends between the first and the second side walls, and an outer wall, which extends between the first and the second side walls, substantially parallel to the inner wall, and forms, with the profile body, a closed hollow profile, wherein a first wire-form primary reinforcing element and a second wire-form primary reinforcing element are arranged in the inner wall, parallel to the axial direction of the spacer profile, wherein the first primary reinforcing element is arranged in a first portion of the cross section of the profile body, in which the inner wall is adjacent to the first side wall, and wherein the second primary reinforcing element is arranged in a second portion of the cross section of the profile body, in which the inner wall is adjacent to the second side wall, such that the first and second primary reinforcing elements have not more than approximately 50% of their cross-sectional surface area arranged in the first and the second side walls, respectively, and that the distance between the centres of gravity of the cross-sectional surface areas of said reinforcing elements is approximately 40% of the distance between the side walls or more, but at least approximately 4 mm. |
