PCT No. PCT/DE92/00434 Sec. 371 Date Apr. 18, 1994 Sec. 102(e) Date Apr. 18, 1994 PCT Filed May 28, 1992 PCT Pub. No. WO92/21512 PCT Pub. Date Dec. 10, 1992A 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 space apart in a lying mold having an essentially V-shaped cross-section and the spacings between the fillets are filled with a mixture of san and isocyanate. Between the backs of the fillets and the sand and isocyanate mixture on the one hand and a countermold on the other hand is introduced a rigid foam layer, whereas part of the rigid foam partially impregnates the sand and isocyanate mixture. The areas of the mixture that are not impregnated with rigid foam are removed after curing the rigid foam layer. A molding box for carrying out this process is also disclosed.
