- the storage installation 1 further comprises a metal connecting strip (not shown) making it possible to connect the sealing wall of the lid and the primary sealing membrane 13 of the ceiling wall 4 in a sealed manner.
- the secondary thermally insulating barrier 10 of the ceiling wall 4 comprises a row of secondary end insulating blocks 34 adjacent to the transverse end edge 25, as shown in .
- the end secondary insulating blocks 34 are juxtaposed to each other in the longitudinal direction L and are anchored to the upper load-bearing wall 8 by means of fixing devices 41.
- the end secondary insulating blocks 34 are arranged in staggered with the secondary insulating panels 14 of the row directly adjacent to the secondary end insulating blocks 34. Indeed, the interface between two secondary insulating end blocks 34 adjacent is not aligned with the interface between two insulating panels secondary 14 adjacent.
- the secondary insulating end blocks 34 have a generally parallelepipedal shape and each have two side faces perpendicular to the longitudinal direction L.
- Each side face comprises a lower protrusion 46 comprising a bearing surface and an upper protrusion 47, as shown in particular Figures 5 and 6.

Thanks to this arrangement, it is possible to distribute any thickness differences that may result from differences in contraction, in service, between the end insulating blocks on the one hand, and the insulating panels on the other. These differences in contraction may result from different rigidities and/or different thermal behaviors. By spacing the interfaces, we avoid accumulating all the deviations at the same point, which avoids degrading the flatness of the membranes.
- the primary insulating panels 18 and the secondary insulating panels 14 are also staggered along the longitudinal direction L, which means that the interface between two adjacent secondary insulating panels 14 in the longitudinal direction L is misaligned with the interface between two adjacent primary insulating panels 18 in the longitudinal direction L.
