Abstract:
1. An insulation panel comprising: an inner layer of a first material having an inner surface and an opposing outer surface, an outer layer of a second material having an inner surface and an opposing outer surface, said inner surface of said outer layer facing toward said outer surface of said inner layer, at least one intermediate rigid layer of a third material having an inner surface and an opposing outer surface, said inner surface of said at least one intermediate layer facing toward said outer surface of said inner layer, said outer surface of said at least one intermediate layer facing toward said inner surface of said outer layer, said at least one intermediate layer being positioned in a spaced relationship with said inner layer and with said outer layer so a first air space is formed between said inner surface of said outer layer and said outer surface of said at least one intermediate layer and a second air space is formed between said inner surface of said at least one intermediate layer and said outer surface of said inner layer, upper and lower plates extending generally transversely to said inner and outer surfaces of each of said inner layer, said outer layer, and said at least one intermediate layer such that said upper plate seals an upper end of each of said first and second air spaces and said lower plate seals a lower end of each of said first and second air spaces, at least one upper and at least one lower first openings in upper and lower portions of said outer layer so said first air space is in open communication with ambient air so as to permit airflow between said at least one upper and lower openings and thereby create heat exchange between said inner surface of said outer layer and said outer surface of said at least one intermediate layer and the ambient air as ambient air passes through said at least one upper and lower openings and flows along said first air space due at least to convection, wherein said inner layer is imperforate so air cannot flow through said inner layer, and wherein said at least one intermediate layer is imperforate so air cannot flow through said at least one intermediate layer such that said second air space is not in communication with said inner surface of said inner layer and said first air space, at least one upper and at least one lower second openings in said at least one intermediate layer so that said inner surface of said at least one intermediate layer and said outer surface of said inner layer are in an open heat exchange relationship with ambient air flowing through said second air space between said inner layer and said at least one intermediate layer.
