A heat insulating molded body made of inorganic material and inorganic reinforcement fibers is disclosed, as well as a process for producing the same and its use. The molded body is characterized by the following composition: (a) 30-70 wt. % blown vermiculite; (b) 15-40 wt. % inorganic binder; (c) 0-20 wt. % infrared opacifier; (d) 15-50 wt. % microporous material; (e) 0.5-8 wt. % reinforcement fibers which contain maximum 2 wt. % B,O,and at most 2% alkalimetal oxide, based on the weight of the reinforcing fibers.

Heat insulating moulded body and process for producing the same

The invention relates to a panel-shaped, evacuated and thermally insulating molded element which contains pressed and optionally hardened, microporous insulating material, wherein the insulating material is in one or more sheathed and evacuated layers, and the molded element has a surface with a lamellar structure, the lamellae being produced by elongate incisions into the surface and having a depth of 40 to 95% of the thickness of the molded element. The invention also relates to a method of insulation for curved surfaces with thermally insulating material, wherein the molded element is made to fit with the surface with a lamellar structure snugly against the curved surface, is fixed in position, and the vacuum is destroyed in at least one layer.
