Abstract: A molded thermal insulator body, in particular a thermal insulator plate comprises, for the purposes of a better flexibility, a prepressed base body (1) substantially containing at least one center layer (3), predominantly made of a highly dispersed ceramic material such as silica aerogel (SiO.sub.2), and an upper and a lower support layer (2), predominantly made out of flexible paper, foil, cardboard, or felts of ceramic material, or of a mixture of at least two of the same, preferably of ceramic paper, foil or cardboard, and wherein the base body is enveloped by a shrinkable plastic foil (4).
