A first thermal break spans the insulation layer and is in contact with both the metallic exterior surface and the metallic interior surface. A frame supports the cover. This frame has a second metallic exterior surface separated from a second metallic interior surface by at least a second insulation layer, where the second metallic exterior surface is thermally isolated from the second metallic interior surface by a thermal break component. A non-metallic, thermally insulating gasket is disposed between the cover and the frame.
