Abstract
A structure insulated for example by expanded polyurethane or the like, such as a refrigerator cabinet or freezer cabinet, comprises a plurality of compartments separated from each other by an interspace, the insulating material injected into said structure enclosing said compartments on all sides except the access side and positioning itself in the interspace. At opposing ends of said interspace there are positioned separator means openable in the manner of an envelope and arranged to separate, during its injection into the structure, the insulating material directed around the compartments from that directed into the interspace, said separator means comprising a flat portion parallel to the sides of the insulated structure.
