ABSTRACT:
An insulating plate unit comprises a first engaging end and a second engaging end. The first fin extends longitudinally from an upper edge of the first engaging end and along a length of the upper edge. A first wing extends longitudinally from a lower edge of the first engaging end and along a length of the lower edge. The first wing extends to a distance greater than that of the first fin. The first wing has an inward facing surface and an outward facing surface. A channel is defined by the first fin and the first wing. A recess is formed in the outward facing surface and extends along the length of the lower edge of the first engaging end. A ridge is formed on the inward facing surface and extends along the length of the lower edge of the first engaging end. A groove is correspondingly formed in the second engaging end for engaging with the ridge of another insulating plate unit. The second engaging end is complimentary to the first engaging end so that the insulating plate units can be interconnected.
