The free ends of the layers are engaged by undercut portions, e.g. hook-shaped projections 19, 20, of walls 11, 14 of the channels and the space between the layers is filled with a plastics thermal insulation foamed in situ. The breaker strip may be formed as a moulded construction of four lengths joined together at their ends with moulded corners to provide a rectangular door frame. The evaporator coil (not shown) is embedded in the foam insulation in contact with the layer 2.
