Abstract

The invention relates to composite elements having a structure comprising the following layers: (i) between 2 and 20 mm of metal, (ii) between 10 and 300 mm of polyisocyanate polyaddition products which can be obtained by reacting (a) isocyanates with (b) polymer polyols, as compounds which react with ioscyanates, and (iii) between 2 and 20 mm of metal. The invention is characterised in that the metallic layers (i) and (iii) are fixed in such a way that area (R) is formed between the same for layer (ii), (R) is sealed, with the exception of at least one opening for filling (R) and at least one other opening, and the sealing of (R) is checked by measuring the pressure difference on the opening(s), before filling (R) with the starting components for producing (ii).
