[ I claim:] [1.] A container compartment for refrigerators and similar household electrical appliances, said container compartment comprisinga rear wall,a wall opposite the rear wall and forming a door of said compartment,an upper wall,a lower wall and two lateral walls,said walls having a composite structure formed from an outer sheet and an inner sheet of rigid material having a thickness substantially less than that of an interspace existing between them, said interspace being filled with expanded polystyrene, the expanded polystyrene occupying the interspace being directly bonded to the inner and outer sheets of rigid material, the interspace being divided into two portions along center planes so that one resultant portion is inserted into the remaining portion, said two portions being joined together along edges of said rigid material sheets, andat least one wall chosen from the upper wall, the lower wall and the lateral walls comprises within said interspace a seat freely housing a laminar element opaque to infrared rays,the laminar element opaque to infrared rays being formed from a plurality of aluminum sheets spaced apart by at least one sheet of material having properties of expanded polystyrene.
