A thermal insulation material, and a method for its manufacture, in which the material is suited to underwater use. The material includes a matrix 20 of cured polymer material, most preferably polyurethane, in which are embedded insulation bodies 10 each including a core 12 of foamed material and an outer structural plastics layer 14 . The materials and the manufacturing conditions are chosen such that temperatures within the low density bodies during manufacture are not sufficient to destroy the foamed cores. The result is a material with excellent thermal insulation properties |
