ABSTRACT OF THE DISCLOSURE The invention relates to heat insulating elements which may be connected with similar elements in a string to form a heat insulator used as a screen for limiting heat losses from heated material, e.g. bars and slabs in rolling mills. Such screens are provided for example in the form of strings of such heat insulating elements composed of metal shells containing insulating material. These screens may form curtains and/or covers for the hot material. Containing chambers for the hot material may be provided with such strings of elements and the chambers may also comprise means for limiting heat conduction losses through the material supports therein. The screens may be collapsed over the hot material thereby completely surrounding and insulating the material from loss of heat. A displaceable chamber installation is also described for limiting heat loss when holding and transferring hot material between processing stages.
