Abstract
Abstract A refrigerator cabinet having walls of a sandwich construction formed by an inner lining, an outer surface and an insulating body of foamed polyurethane plastic formed in situ therebetween. Channel-shaped breaker strips surround the opening of the cabinet and seal an edge of the insulation. The breaker strips are provided with a pair of ribs along the legs of the channel, and spacer means are arranged between the inner lining and outer surface when placed within the breaker strip so as to keep them spaced apart and properly located during the fabrication of the sandwich construction.
