Common sandwich constructions used in construction consist of a foam core and two metallic cover layers. In the vast majority of cases, it is a core made of polyurethane foam (PUR) or mineral wool (MW). The bond (adhesion or gluing) of the cover layers with the shear-resistant core results in a high load-bearing capacity and great rigidity for the sandwich panel .
The linear sandwich theory is used to calculate the load-bearing capacity of sandwich panels .
At the same time, the core ensures very good thermal insulation of the building envelope . Sandwich constructions are quick to assemble and are mainly used in the roof and wall area of industrial, office and administrative buildings and cold stores. Around 12 million m² of sandwich panels are currently being laid in Germany each year . In Europe as a whole, it is 80–100 million m².
In the context of the major fire of Grenfell Tower in London in June 2017, the use of sandwich panels in fire protection was discussed.
