How the metal-faced sandwich panel is composed?

Metal-faced sandwich panel by EuroPanels is composed from construction-insulation featured core and it is glued into the core metal facings (inner and outer).
The core can be made out of a polyurethane rigid foam (PUR) or a polystyrene (EPS).

In case of PUR, the foam is the glue, so we call such a panel a continuous-cored panel.

For EPS, there are EPS blocks used for production that are glued into facings with a poluyrethane-based glue. This kind of products are referred to us as discontinuous-cored ones.
