  • the panel components can be realized as wall, roof or ceiling panels. It is possible to provide foamed concrete or cement foams as an insulating layer, which is particularly advantageous on construction sites because such foams harden in the air and are easy to produce on the construction site by means of a foam generator. It is surprising that such sandwich constructions are stable at all. can be made, since typically both the expansion coefficient in the stretch layer is lower and the shrinkage of the material during curing. In addition, it is surprising that the sandwich panels are sufficiently permanently stable, since the E-modules of the individual layers are different, which is to be considered in a load distribution.
