Abstract: The invention relates to a sealed and thermally insulating tank wall comprising a thermally insulating barrier defining a support surface for a sealing membrane, the thermally insulating barrier comprising two adjacent insulating panels jointly delimiting an inter-panel space, the tank wall further comprising an insulating insert arranged in the inter-panel space so as to fill the inter-panel space, the insulating insert comprising an insulating core at least partially covered by a wrapper, the insulating core comprising layered glass wool, the layered glass wool comprising laps of fibers superposed in a direction of layering, the insulating insert being arranged in the inter-panel space in such a way that the direction of layering of the layered glass wool is parallel to a widthwise direction of the inter-panel space.

Abstract: The invention relates to a method for manufacturing a sealed and thermally insulating tank wall comprising: providing a thermally insulating barrier comprising two insulating panels delimiting an inter-panel space, providing an insulating insert comprising a wrapper completely covering an insulating core, inserting a suction nozzle of a suction system into the insulating insert through an orifice in the wrapper, applying a vacuum pressure in the insulating insert so as to reduce the thickness of the insulating insert through vacuum pressure, inserting the insulating insert into the inter-panel space while maintaining the suction of the suction system, when the insulating insert has been inserted into the inter-panel space, removing the suction nozzle from the insulating insert.

Abstract: The present invention relates to a preparation of a block of fiber-reinforced polyurethane/polyisocyanurate foam in which the expansion of the foam is constrained by the walls of a double belt laminator forming a tunnel, the block of fiber-reinforced polyurethane/polyisocyanurate foam being composed of cells storing a gas, advantageously having low thermal conductivity, and exhibiting a density of less than 50 kg·m?3 with a content of fibers Cf representing at least 4% by weight of the block of fiber-reinforced foam, in which the impregnation time of the fibers ti is less than the cream time tc of the polyurethane/polyisocyanurate foam.
