  • These control means are manual or motorized and can be coupled to the rolling shutter control means 10 or separate and independent thereof.
  • the means for controlling the progress of the insulating blanket 210 are, for example, independent of the means for controlling the unwinding of the apron 5 of the insulating flap 10.
  • the insulating blanket 210 can then be unrolled whatever the wound or unwound configuration of the apron 5 of the shutter 10.
  • the deployment means 220 of the insulating blanket 210 act automatically on it as it unfolds: the outer wall 212 is guided by the ramp 225 of the slide 221 as it unfolds, and thus away from the outer wall 211 which is guided by the right slide 222.
  • the channels 243 being open laterally, they fill with air as the two outer walls 111, 112 deviate.
  • the support membranes may be replaced by rods or support blades similar to those described in the first embodiment, fixed on the outer walls of the insulation blanket and whose lateral ends cooperate with the guide rails of the insulation blanket as previously described.

  • the insulating blanket 310 is controlled, for its winding and unwinding, by the control means of the winding and unwinding of the apron 5 of the shutter 10.
  • the deployment means 320 of the insulating blanket 310 comprise mechanical bracing means 321 disposed between the two outer walls 311, 312 of the insulating blanket 310 and movable between a folded position ( figure 9 ) in which they allow the flattening and winding of the insulation blanket 310 to be lifted and a raised position ( figure 10 ) in which they force the outer walls 311, 312 of the insulating blanket 310 to move away from each other.
  • bracing means 321 comprise a plurality of bracing fingers 321 which are for example coupled to the lateral edge of the apron 5 of the shutter 10.

  • the bracing fingers 321 In their folded position, the bracing fingers 321 extend substantially parallel to the deck 5 of the shutter 10.
  • the spacing between two bracing fingers 321 coupled to the deck 5 of the shutter 10 is preferably greater than or equal to the length of each spacing finger 321, so that, in their folded position, said spacer fingers 321 align one behind the other, along the edge of the apron of the shutter, without touching.
  • the insulation blanket 310 is then flattened against the inner wall of the apron 5 of the shutter 10 and can be wound around the winding bar 7 with it.
  • these spacer fingers 321 act on the other free outer wall 312 of the insulating blanket 310, in a localized manner on its lateral edges ( figure 10 ).
  • the insulation blanket 310 comprises a support membrane 332 fixed against its free outer wall 312 and substantially stiffer than this outer wall 312. In their raised position, the spacer fingers 321 push back the lateral edges of said support membrane 332 which then deviates from the outer wall 311 of the insulating mat 310 connected to the deck 5 of the shutter 10.
  • each spacer finger 321 is approximately equal to the desired maximum thickness of the insulation blanket 310, for example about 6 centimeters in this particular embodiment.

  • the insulating mat 310 runs at the same time as the apron 5 of the shutter 10.
  • the deployment means 120 of the insulating blanket 110 being controlled by independent control means, the automation comprises a delay which actuates the tie rods after complete unwinding of the insulating blanket 310, or the user waits for example the complete unwinding of the insulating blanket 310, then actuates the tie rods 350 manually to tension them and raise the spacing fingers 321. These push back the free outer wall 312 of the insulating blanket 310 in a direction perpendicular to the unwinding plane of the insulating blanket 310 and thus separate it the outer wall 311 of the insulating mat 310 secured to the apron 5 of the shutter 10.
  • the channels 343 being open laterally, they fill with air as the two outer walls 311, 312 of the insulation blanket 310 deviate.

  • seals 61, 128, 61, 228, 610 are preferably provided in each channel 6, 121; 6, 221, 222, 600 which extend from the inner faces of the side walls of each slide 6, 121; 6, 221, 222, 600 inwardly of said slide.
  • These sealing means ensure the airtightness between each slide and the mechanical part that it receives, namely, the apron 5 of the shutter 10 and / or the outer walls of the insulation blanket, with or without membrane support and / or support rods.
  • sealing means comprise, for example, flexible plastic seals in the form of a flexible lip or a tubular shape, the plastic material being able to be chosen to provide a low coefficient of friction and / or to be provided with a surface treatment or coating promoting slippage, such as a fluorine or perfluorinated substance treatment or a fibrous coating in the case of a flocked joint; they may also comprise felt pads or brushes whose bristles extend between the side walls of each slide.
