Claim:
A no-through-metal enclosure, the enclosure comprising: a floor comprised of a plurality of generally C-shaped panels, each of said panels being formed from a sheet of bent metal, and each of said panels comprising: an outer wall which comprises the back of the generally C-shaped panel; two legs attached to opposite terminating ends of said outer wall which extend from the plane of the outer wall; and two connecting surfaces attached to the terminating ends of each of the legs, each connecting surface extending inward from the legs towards each other in a plane generally parallel with the outer wall, the two connecting surfaces being spaced from each other by a distance; wherein said plurality of panels of said floor are connected adjacently together along the length of said legs of said panels such that the outer walls of the plurality of panels are generally linear; wherein a panel whose outer surface forms a portion of an outer metal surface of said floor is connected to an interior metal surface of said floor only via insulative strips which are placed on the side of said connecting surfaces opposing the outer wall; and wherein said floor has no-through-metal from said outer metal surface to said interior metal surface; and a wall substantially perpendicularly connected to said floor, said wall comprised of at least two generally C-shaped panels, each of said panels being formed from a sheet of bent metal, and each of said panels comprising: an outer wall which comprises the back of the generally C-shaped panel; two legs attached to opposite terminating ends of said outer wall which extend from the plane of the outer wall: and two connecting surfaces attached to the terminating ends of each of the legs, each connecting surface extending inward from the legs towards each other in a plane generally parallel with the outer wall, the two connecting surfaces being spaced from each other by a distance; wherein said at least two panels are partially connected together via a portion of said connecting surfaces only via insulative strips which are placed on the side of said connecting surfaces opposing the outer wall and such that the length of the connected panels is greater than the length of one of the individual panels; and wherein said wall has no-through-metal between the outer walls of the connected panels.
