The invention relates to a method for producing a sealed and thermally insulating wall for a fluid storage tank, comprising the steps of: ? attaching a plurality of anchoring elements (1) to a support structure (2); ? installing modular formwork elements (3) on the support structure (2), the modular formwork elements (3) having a shape that protrudes relative to the support structure (2) and that defines, with the support structure (2) and the plurality of anchoring parts (1), compartments (4) having an open side opposite the support structure (2); ? spraying insulating foam into said compartments (4) through the open side so as to form a plurality of insulating sectors (5) made from sprayed insulating foam; ? arranging insulating junction elements (8) in a stressed position in which they are stressed between said insulating sectors (5) and capable of expanding when said insulating sectors (5) contract, so as to ensure continuity of the thermal insulation; and ? attaching a sealing membrane to said anchoring elements (1).
