A holder for one or more elongate slats (70, 72) for shading systems and daylight control systems in the pane intermediate space of insulating glasses, comprising: an elastic or resilient compensating unit comprising two profiles (50, 150) which are located opposite one another and engage in one another, and which are arranged so as to be movable relative to one another in the longitudinal direction of the elongate slats (70, 72), which form a common inner space in which a spring element is accommodated, wherein the spring element is compressed in the case of a temperature-induced expansion of the elongate element(70, 72) and relaxes when the elongate slats (70, 72) contract in the longitudinal direction of the elongate slats (70, 72), characterized in that the spring element is held in the inner space with a clamping or friction fit wherein a compensating movement in the longitudinal direction is possible; the common inner space of the compensating unit is delimited by web parts (20, 120) running transversely with respect to the longitudinal direction of the elongate slats (70, 72) and respectively one leg (52, 152), extending in the longitudinal direction, of the movably arranged profiles (50, 150) of the compensating unit, wherein the web parts (20, 120) are provided as a stop for the legs (52, 152); the compensating unit comprises, on the side opposite the inner space and facing the elongate slats, a further profile for accommodating the elongate slats and, on the side opposite the further profile, a still further profile as a spacer from a window frame or carrier element or for accommodating one or more further elongate slats; the further profiles (30, 130) are each respectively formed in one piece with a correspondingly movably arranged profile (50, 150) of the compensating unit, wherein each of said further profiles with said corresponding movably arranged profile have a common web part (20, 120); in each case the outer side of a leg (54, 154) of the profiles (50, 150) of the compensating unit is substantially aligned with the outer side of a leg (34, 134) of the relevant further profile (30, 130) located on the same web side when viewed in the transverse direction to the elongated slats (70, 72), wherein the respective other legs of the movably arranged profiles (50, 150) of the compensating unit are not aligned with the leg (32, 132) located on the same web side but are arranged offset into the profile interior with respect to the longitudinal axis thereof and are surrounded on the outside by the other leg (154; 54) of the relevant profile (50, 150) in such a manner that the components consisting in each case of a displaceably arranged profile (50, 150) of the compensating unit and a further profile (30, 130) with a common transverse web (20, 120) are identical. an elastic or resilient compensating unit comprising two profiles (50, 150) which are located opposite one another and engage in one another, and which are arranged so as to be movable relative to one another in the longitudinal direction of the elongate slats (70, 72), which form a common inner space in which a spring element is accommodated, wherein the spring element is compressed in the case of a temperature-induced expansion of the elongate element(70, 72) and relaxes when the elongate slats (70, 72) contract in the longitudinal direction of the elongate slats (70, 72), characterized in that the spring element is held in the inner space with a clamping or friction fit wherein a compensating movement in the longitudinal direction is possible; the common inner space of the compensating unit is delimited by web parts (20, 120) running transversely with respect to the longitudinal direction of the elongate slats (70, 72) and respectively one leg (52, 152), extending in the longitudinal direction, of the movably arranged profiles (50, 150) of the compensating unit, wherein the web parts (20, 120) are provided as a stop for the legs (52, 152);

in each case the outer side of a leg (54, 154) of the profiles (50, 150) of the compensating unit is substantially aligned with the outer side of a leg (34, 134) of the relevant further profile (30, 130) located on the same web side when viewed in the transverse direction to the elongated slats (70, 72), wherein the respective other legs of the movably arranged profiles (50, 150) of the compensating unit are not aligned with the leg (32, 132) located on the same web side but are arranged offset into the profile interior with respect to the longitudinal axis thereof and are surrounded on the outside by the other leg (154; 54) of the relevant profile (50, 150) in such a manner that the components consisting in each case of a displaceably arranged profile (50, 150) of the compensating unit and a further profile (30, 130) with a common transverse web (20, 120) are identical.
