<p>An insulated panel for rolling closures. The panel has a front wall and a back wall joined by side walls, and is filled with insulation. The side walls have thermal breaks formed by spacers. The size of the spacers can vary to vary the thickness of the panel. In one embodiment of the invention, the panel has a hinge socket formed in the back wall adjacent one side wall. An extension of the back wall, projecting past the other side wall, carries a hinge pintle. In another embodiment, the panel has a hinge socket in the back wall adjacent each side wall. A separate hinge member with a hinge pintle on each side joins two adjacent panels together via their nearest hinge sockets. The invention also relates to closures incorporating the above panel embodiments, and to a method of making the panels.</p> |
