A thin and flexible, effectively heat insulating material for articles of clothing or for furniture use, e.g. as a water bed sheet, consists of outer textile cover layers (2 and 10) and one or more inner layers of a thin plate material (4 and 8) of expanded polystyrene of a thickness of 1-2 mm. Between two such layers is mounted a thin layer (6) of quilting cotton or plastic foam, which prevents the polystyrene layers from rubbing directly against each other. The polystyrene layers may be broken locally, but they are kept in place by the material being quilting stitched (12, 24). The material can to a wide degree replace electrically heated pads etc., and as far as cleaning is concerned it can be handled and treated as ordinary laundry.
