An oven has a first conveyor, a first burner that directs heat toward the first conveyor from above the first conveyor, and a second burner directs heat toward the first conveyor from below the first conveyor. A method includes providing foodstuff on a conveyor, exposing the foodstuff to heat directed toward the foodstuff from above the conveyor, and exposing the foodstuff to heat directed toward the foodstuff from below the conveyor. Another oven has a first conveyor and first conveyor insulators that surround the first conveyor and define a first zone. Another method includes introducing foodstuff to a first conveyor belt within a first insulated zone, introducing heat into the first insulated zone, and retaining a portion of the heat within the first insulated zone. Another oven has an insulated cooking zone that closely envelopes a cooking path and an insulated oven zone that substantially envelopes the cooking zone.

1. An oven, comprising: an uppermost oven top wall at least partially defining an uppermost boundary of an interior space of the oven;a first conveyor comprising a length and a width, the first conveyor being configured to move foodstuff along the length; anda first insulative barrier disposed vertically above the first conveyor, the first insulative barrier being configured to at least one of (1) restrict vertically upward movement of heated fluid away from the first conveyor and (2) promote movement of the heated fluid along at least one of the length and the width prior to the heated fluid exiting a space between the first insulative barrier and the first conveyor, the first insulative barrier being vertically offset relative to the oven top wall and the space vertically above and adjacent the first insulative barrier being in fluid communication with the interior space of the oven vertically below and adjacent the oven top wall. 2. The oven according to claim 1, further comprising: a first burner disposed vertically above the first conveyor, the first burner being configured to emit at least one of heat and the heated fluid into at least one of (1) the space between the first insulative barrier and the first conveyor and (2) a space between the first burner and the first conveyor. 3. The oven according to claim 2, wherein the first burner is configured to at least one of (1) restrict vertically upward movement of heated fluid away from the first conveyor and (2) promote movement of the heated fluid along at least one of the length and the width prior to the heated fluid exiting the space between the first burner and the first conveyor. 4. The oven according to claim 3, wherein the first burner and the first insulative barrier are configured to cooperate in requiring the at least one of the heat and the heated fluid to move along at least one of the length and the width until the at least one of the heat and the heated fluid are no longer vertically underneath either of the first burner and the first insulative barrier prior to the at least one of the heat and the heated fluid is allowed to rise vertically higher than at least one of the first burner and the first insulative barrier. 5. The oven according to claim 4, wherein the first burner is substantially adjacent the first insulative barrier in the lengthwise direction. 6. The oven according to claim 4, further comprising: a second insulative barrier substantially adjacent the first burner along a lengthwise side of the first burner opposite the lengthwise side of the first burner to which the first insulative barrier is substantially adjacent. 7. The oven according to claim 4, wherein a vertically lowest portion of the first burner is vertically offset a first distance from the first conveyor and the first insulative barrier is vertically offset from the first conveyor substantially the same first distance. 8. The oven according to claim 4, further comprising: a plurality of additional insulative barriers configured to cooperate with the first insulative barrier to extend substantially encircle a portion of the first conveyor. 9. An oven, comprising: an uppermost oven top wall at least partially defining an uppermost boundary of an interior space of the oven;a first conveyor comprising a length and a width, the first conveyor being configured to move foodstuff along the length; anda duct configured to substantially encircle at least a portion of the first conveyor, the duct being vertically offset relative to the oven top wall and the space vertically above and adjacent the duct being in fluid communication with the interior space of the oven vertically below and adjacent the oven top wall, the duct comprising: at least one insulative panel; andat least one infrared burner;wherein a vertical offset distance of the duct from the first conveyor comprises the greater of (1) an offset distance required to allow foodstuff to move along the length without contacting the duct and (2) an offset distance selected to substantially optimize delivery of at least one of heat and heated fluid to foodstuff within the duct. 10. The oven according to claim 9, wherein the duct extends along a majority of the length of the first conveyor. 11. The oven according to claim 9, wherein the duct defines an insulated cooking zone substantially enclosed within a larger insulated oven zone of the oven. 12. The oven according to claim 9, wherein the duct comprises openings configured to allow mechanical components of the first conveyor to extend therethrough in a widthwise direction. 13. The oven according to claim 9, wherein the duct substantially directs the heat and the heated fluid along the length of the conveyor until the heat and the heated fluid escape an open lengthwise end of the duct. 14. An oven, comprising: a first conveyor comprising a first length and a first width, the first conveyor being configured to move foodstuff along the first length;a second conveyor comprising a second length and a second width, the second conveyor being configured to move foodstuff along the second length, wherein the second conveyor being disposed substantially vertically underneath the first conveyor and wherein the space between the first conveyor and the second conveyor is substantially free of a conveyor substantially similar to either of the first conveyor and the second conveyor;a first duct configured to substantially encircle at least a portion of the first conveyor, the first duct comprising: at least one first insulative panel; andat least one first infrared burner; anda second duct configured to substantially encircle at least a portion of the second conveyor, the second duct comprising: at least one second insulative panel; andat least one second infrared burner;wherein at least a portion of the second duct is disposed substantially vertically underneath the first duct;wherein the first duct and the second duct are substantially enclosed within a larger insulated oven zone of the oven and wherein an empty space exists between a bottom of the first duct and a top of the second duct. 15. The oven according to claim 14, wherein a first vertical gap between the top of the first conveyor and an upper interior wall of the first duct is substantially similar to a second vertical gap between the top of the second conveyor and an upper interior wall of the second duct. 16. The oven according to claim 14, wherein at least one of the first duct and the second duct comprise an open lengthwise end to allow exit of the heat and the heated fluid. 17. The oven according to claim 14, wherein at least one of the first duct and the second duct comprise a plurality of substantially plate-like insulative panels. 18. The oven according to claim 14, wherein the heat and the heated fluid exiting at least one of the first duct and the second duct are free to move into at least one of the empty space, a space below the second duct, and a space above the first duct while remaining within the insulated oven zone. 19.
