Disclosed is a non-inflammable insulating, composite material capable of being shooted onto a surface to be coated, such as the wall of a building to be insulated. This material comprises a fibrous-like, synthetic forsterite obtained by calcination of chrysolite asbestos fibers at a temperature from 650.degree. to 1450.degree.C; an inorganic, ligthweight filler selected amongst vermiculite, perlite and their mixtures; and a non-inflammable, hydraulic or silicate binder contained in such an amount as to make the material sufficiently adhesive to be shooted as a coating, either as such or after wetting, onto the surface to be insulated. The weight ratio of the synthetic forsterite to the inorganic filler is ranging from 20:80 to 80:20 to adjust the volumic weight of the final product from about 0.20 to about 0.50 gram per cm3. Also disclosed are methods of manufacturing such a non inflammable, insulating, composite material in a wet, ready-to-be-shooted form.
