ABSTRACT:
A hollow body which has a flexible envelope and can be pressurized from inside by a pressure medium, the envelope consisting of a foam material, preferably neoprene, with closed cavities whose volume can be altered by changes in the pressure medium to correspondingly alter the thermal insulation capacity of the envelope. A coating may be applied to the foam material on the outside of the hollow body to enhance the stability of its shape when inflated.
