An insulating system for a refrigerating apparatus is described in which the side wall (1 min ), the upper wall (1) and the lower wall (1) of the cooling compartment (20, 21) are formed by two plates of air-impermeable material (11, 16, 30, 31) parallel to one another and with their facing surfaces made reflecting, and by a seal (14) which is also impermeable to air, which together form a cavity which is in the form of a hollow parallelepiped and in which a certain degree of vacuum is created. The two plates (11, 16, 30, 31) are held apart and parallel to one another by a grid (12, 33) of thermally insulating material, the profile of which is shaped in such a way that the surface of contact between the said spacer grid (12, 33) and the said two plates of air-impermeable material (11, 16, 30, 31) results in being as small as possible. The cooling compartment (20, 21) is completed by the addition of a door (4, 5) and an insulating back wall (2, 9) in conventional manner.
