Abstract: A sealed insulating tank in which the secondary insulating barrier, the secondary sealing membrane, and the primary insulating barrier essentially consist of a set of prefabricated panels juxtaposed on the supporting structure. Sealing strips are arranged so that they overlap the adjoining edge zones of the leaktight linings of the prefabricated panels in order to complete the secondary sealing membrane between the prefabricated panels. Insulating blocks arranged on the sealing strips have a layer of thermal insulation covered by a rigid board and a reinforcing mat having a stiffness under tension which is greater than or equal to the stiffness under tension of the sealing strips and is glued to the layer of thermal insulation on a face of the layer of thermal insulation opposite the rigid board, the insulating block being each time fixed to the prefabricated panels by gluing the reinforcing mat to the underlying sealing strip.
