Abstract

In a process for making a thermal insulating body from highly insulating material, opacifier, reinforcing fiber mix and, if desired a binder, the materials are mixed together. The opacifier and/or the reinforcing fiber mix being mixed with a dispersant for forming a first-stage mix, which is then nextly mixed with the rest of the materials. The material is then compacted.
