  • FIG. 9 show various aspects of another Embodiment of an insulation strip in this Embodiment is the frame structure 7 from an im essentially continuous longitudinal wall 4 and two on their End arranged transverse webs 6 formed. These crossbars serve to absorb the insulation material and cause it Desired and required stabilization of the insulation strip.
  • the insulation material 14 is on the side of the longitudinal wall on both Pages arranged, symmetrical in the case of Figure 9, in the case of Figures 10 and 11 asymmetrical.
  • the one shown in Fig. 9 Longitudinal wall 4 has interruptions 13, which are in Fig. 10 and 11 longitudinal walls 4 not shown. An interruption of the Longitudinal wall or recesses in the longitudinal wall inhibit the Heat flow over the insulation material due to a lower thermal conductivity is reduced.
  • connection profile 12 to the holding contour of a metal profile each serve a dovetail that is attached centrally to the outside of the cross profiles 6. Furthermore, the interruptions in the longitudinal wall have the Advantage that this when foaming the insulation material extends through the recesses in the longitudinal wall and thus the two areas of insulation on either side of the Longitudinal walls are formed from a single piece. This increases the mechanical stability of the insulation material.
  • the insulation material is attached to the side of the longitudinal wall 4.
  • This insulating material 14, for. B. foam material can either be glued to the frame structure 7, the in 9, 10 and 11 shown cross profiles an arcuate Have shape and thus hold the foam mass 14 in addition and secure against loosening in relation to the frame structure.
  • the Insulating material can also be similar to that in FIG. 5 described, introduced in that first a closed hollow profile is formed, in which the Foam material 14 is poured, and then the outer Longitudinal walls are milled away in order to achieve the final shape come, which is shown in Fig. 9.
  • Figures 10 and 11 show Similar to FIG. 8, an insulation strip 2, in which at least one Part of the insulating material 14, which in connection with stands the frame structure 7, protrudes from this.
  • This The insulation material 14 can protrude over the entire length the insulation strip be present, or only over Subareas. As mentioned above, it serves as far as the Allow space in the overall arrangement, the additional insulation by reducing the convection space and as a radiation barrier
  • the insulation strip 2 in one of the shown in FIGS. 9, 10 and 11 Embodiments offers good insulation and Thermal insulation properties because the frame structure is thin can be formed because the heat insulating material 14 a Absorbs part of the mechanical load. Thin profiles ensure low heat conduction and thus good Thermal insulation properties.
  • FIGS. 12, 15, 16th and 17 are further embodiments of the Insulation strip shown. These embodiments common that, as from the side views (Fig. 12, 15, 16th and 17) can be seen the insulation strip along its Cross-sections changing in the longitudinal direction.
  • at least one of the longitudinal walls 4 of the Insulation strip 2 is provided with recesses 15, which to the Leads to cross-sectional changes. Otherwise these recesses reduce closed hollow profile of this embodiment additionally the heat flow.
  • the longitudinal wall can only be in one limited area serve as a thermal bridge.
  • the course of the Heat flow is indicated by an arrow Q in FIGS. 12, 15, 16 and 17 indicated.
  • the recesses 15 in the longitudinal wall 4 of the Insulation strips can have different shapes (circle, rectangle, Triangle etc.).
  • FIGS. 13 and 14 Cuts through the insulation strip according to FIG. 12 are shown in FIGS. 13 and 14.
  • 13 corresponds to a section the location identified by A-A from FIGS. 12, 14 a cut at the point marked B-B.
  • the insulation strip additionally an area protruding from the main profile having.
  • this is not absolutely necessary but a flush formation of the foam filling 14 in the Insulation strip 2, the cutouts in at least one of their Longitudinal walls 4 is conceivable and in Fig. 18th shown.
  • Figs. 19 and 20 Another feature is shown in Figs. 19 and 20.
  • the illustrated embodiment of the invention is based on the in Fig. 2 embodiment shown.
  • thermal insulation is another area of thermal insulation Material 18 attached to the insulation strip 2.
  • this additional insulation 18 glued on.
  • a bracket 19 for this additional insulation in be integrated into the frame structure in the form of projections, which additionally increase the radiation area, as in FIG. 20 shown, the additional insulation area can be easily The guide be glued on. Attaching a holding structure 19 offers an additional protection against slipping the insulation material the advantage that the insulation material in this Holding area can also be pinched, or the Holding area with the insulating material a positive Can enter into a connection.
  • One aspect of the insulation strip according to the invention is that since it was recognized that part of the heat-insulating material the mechanical load, the frame structure of the Insulation strip can be thin-walled or on some Areas may have recesses or interruptions. This leads to the fact that the thermal insulation properties of the Insulation strip can be improved without relying on mechanical Having to do without strength properties.
