1. A screen for reflecting radiation, more particularly infrared radiation, intended for use at a given temperature equal to at least 900 degrees C, constituted on the one hand by a first layer (24) of a shining, polished material in order to reflect at least a part of the infrared radiation, and on the other hand by a second layer (21) of a material constituting a support, characterized in that the material of the first layer is not changed when it is raised to the said temperature, in that it comprises, placed between the two first layers, at least one third layer (22 and 23) of a material to hold back the actual radiation emanating from a layer (24) which is nearest to the source of radiation and/or a part of the radiation not reflected by the latter, and in that the layer or layers (22 and 23) placed in between is or are integrated with the two layers adjacent thereto. |
