The invention relates to a panel with a coating which reflects thermal radiation, comprising at least one substrate (1) and at least one thermal radiation-reflecting coating (2) at least on the interior-side surface of the substrate (1), wherein - the panel has a transmission in the visible spectrum range of less than 5%, and - starting from the substrate (1), the coating (2) at least comprises: - an adhesive layer (3) which contains at least one material with a refractive index of less than 1.8, - a functional layer (4) which contains at least one transparent electrically conductive oxide, - an optically high-refractive-index layer (5) which contains at least one material with a refractive index greater than or equal to 1.8, and - an optically low-refractive-index layer (6) which contains at least one material with a refractive index of less than 1.8. |
