Abstract

A shaped thermal insulation body comprises inorganic material. The shaped body has the following, weight-related composition: approx. 20 wt. % inorganic filling material: approx. 40 wt. % opacifier; approx. 10 wt. % fibrous material; and approx. 15 wt. % hardening agent as well as approx. 15 wt. % water. The shaped body only contains a small amount of fumed silica with a comparatively small BET surface. Water glass is excluded during its manufacture. It can be used as a spacer for radiant heaters.
