1. A damper comprising: a frame;a first blade pivotally engaged with the frame, the first blade comprising a first end portion, the first blade comprising a hollow portion for receiving an insulating material;a second blade pivotally engaged with the frame, the second blade comprising a second end portion, the second blade comprising a hollow portion for receiving an insulating material;a first seal connected to the first end portion of the first blade;a second seal connected to the second end portion of the second blade;the first seal and the second seal disposed to cooperatively engage an adjacent first blade end portion and second blade end portion such that a dead air space is created between the adjacent first seal and second seal in a damper closed position; andthe first thermal gap and the second thermal gap disposed within said dead air space in the damper closed position. 2. The damper as in claim 1, wherein the first seal comprises a flexible material. 3. The damper as in claim 1, wherein the second seal comprises a flexible material. 4. The damper as in claim 1, wherein the first seal is hollow. 5. The damper as in claim 1, wherein the second seal is hollow. 6. The damper as in claim 1, wherein the first blade rotates in a direction opposite of the second blade during operation. 7. The damper as in claim 1, wherein the insulating material is foam. 8. The damper as in claim 1, wherein the first seal has a rolling engagement with the second blade end portion as the damper is closed. 9. The damper as in claim 1, wherein the first blade rotates in the same direction as the second blade during operation. 10. A damper comprising: a frame;a first blade pivotally engaged with the frame, the first blade comprising a first end portion;a second blade pivotally engaged with the frame, the second blade comprising a second end portion;a first seal connected to the first end portion of the first blade;a second seal connected to the second end portion of the second blade;the first seal and the second seal disposed to cooperatively engage an adjacent first blade end portion and second blade end portion with the damper in the closed position; anda dead air space disposed between the first seal and second seal with the damper in the closed position. 11. The damper as in claim 10, wherein the first seal has a rolling engagement with the second blade end portion as the damper is closed. 12. The damper as in claim 10, wherein the first thermal gap is disposed between the first seal and the second seal with the damper in the closed position. 13. The damper as in claim 12, wherein the second thermal gap is disposed between the first seal and the second seal with the damper in the closed position. 14. The damper as in claim 10, wherein the first seal comprises a flexible material. 15. The damper as in claim 10, wherein the second seal comprises a flexible material. 16. The damper as in claim 10, wherein the first seal is hollow. 17. The damper as in claim 10, wherein the second seal is hollow. 18. A damper comprising: a frame;a first blade pivotally engaged with the frame;a second blade pivotally engaged with the frame;a first seal connected to a first end portion of the first blade;a second seal connected to a second end portion of the second blade;the first seal and the second seal disposed to cooperatively engage an adjacent first blade end portion and second blade end portion with the damper in the closed position; andwherein the first blade and second blade are filled with insulation. 19. The damper of claim 18 wherein a dead air space is disposed between the first seal and second seal with the damper in the closed position.
