Abstract
The pleasing metal appearance of glass/glass ceramic panels (1) is typically produced by a metal foil/plate (6) on the side of the plate facing away or remote from the observer. According to the state of the art these foils/plates are glued to the glass/glass ceramic panel by means of a transparent adhesive. Because of the different thermal expansion coefficients of the metal foil/plate (6) and the glass/glass ceramic panel (1) this leads to mechanical stress. According to the invention the mechanical stress can be avoided when the metal foil/plate (6) is attached to the glass/glass ceramic panel in a force-locking manner without adhesive. In a preferred embodiment this attachment is made by a clamping joint, e.g. provided by springs. Also it is beneficial to provide a gap between the joined partners, which is filled by a heat conducting compensating mass (8), e.g. silicone oil.
