A partitioning section comprising two metal side walls and a rigid corrugated board of a heat insulating material which is interposed between the side walls so as to hold them apart and out of contact and which is secured to the side walls by adhesive to form an integral assembly. The side walls have at one side edge of the section inturned flanges which are disposed in spaced parallel planes perpendicular to the walls and are each of a width less than one half of the thickness of the section. The other side edge of the section is either planar or provided with similar flanges. Two sections may be fitted together in a portion so that they are disposed in a common plane and two side edges thereof provided with flanges are disposed in abutting relationship, there being heat insulating material between the two pairs of abutting flanges and between each pair of abutting flanges and the opposite side wall. The abutting flanges are secured together by removable joints. |
