  • the threaded stud 52 is carried by the first row 122 of the secondary insulation panels, for example equidistant from the two ends of the secondary insulation panel in the direction perpendicular to the edge 100.
  • the threaded stud 52 engages the panel. primary insulation 154 at the level of the foam block 66, which is the most dense.
  • the threaded stud 52 could engage the primary insulation board 154 at the foam block 67.
  • the secondary insulating panels 121 are designed so that the threaded studs 46 intended to fix the primary corner pieces 37 are fixed between two secondary insulating panels 121.
  • the secondary insulating panels 121 are arranged in the form of a parallel row. at the edge located partially under the flat tab 12 as above.
  • the secondary insulating panels 121 are fixed to the supporting wall 3 by retaining members 29 arranged between the secondary insulating panels 121 as before.
  • the support plate 83 engages the full thickness of the side support walls 87 on the upper edge of the windows 85, providing a strong anchoring against tearing. Similar to the insert 47, the support plate 83 makes it possible to fix two threaded studs 46.
  • windows 86 are provided at the bottom of the side bearing sails 87 to enable the retaining members 29 to engage the entire thickness of the side bearing sails 87 on the lower edge of the windows 86.
  • the absence of the cleats 45 allows the spacings between the secondary insulating panels 121 to be relatively reduced.
  • the windows 85 and / or the windows 86 may be formed in a part of the thickness of the lateral load-bearing webs 87.
  • the contours of the windows 85 and of the windows 86 may be different, as shown, or identical.
  • the window 85 can be replaced by two windows similar to the windows 86, on condition that a notch is provided in the edge of the support plate 83 to accommodate the area of the lateral carrier web 87 located between the two windows.
