A process is disclosed for manufacturing an angular insulating wall element consisting of an angular rigid foam plate linked to brick fillets. Angular, one-piece fillets are spaced a part in a lying mould having an essentially V-shaped cross-section and the spacings between the fillets are filled with a mixture of sand and isocyanate. Between the backs of the fillets and the sand/isocyanate mixture on the one hand and a countermould (10) on the other hand is introduced a rigid foam layer, whereas part of the rigid foam partially impregnates the sand/isocyanate mixture. The areas of the mixture that are not impregnated with rigid foam are removed after curing the rigid foam layer. A moulding box for carrying out this process is also disclosed.
