According to one embodiment, a flood vent includes a frame forming a fluid passageway through an opening in a structure. The flood vent further includes a door pivotally mounted to the frame in the fluid passageway for allowing a fluid to flow through the fluid passageway. The door has two opposing faces that include a first face and a second face. The flood vent further includes a first float positioned within the door in a location in-between the first face and a second float. Additionally, the first float is configured to allow the door to pivot in a first direction. The flood vent further includes the second float positioned within the door in a location in-between the second face and the first float. Furthermore, the second float is configured to allow the door to pivot in a second direction.

1. A flood vent, comprising: a frame forming a fluid passageway through an opening in a structure;a door pivotally mounted to the frame in the fluid passageway for allowing a fluid to flow through the fluid passageway, the door having an outer perimeter defined by a top edge of the door, a bottom edge of the door, a first side edge of the door, and a second side edge of the door; andone or more pieces of insulation positioned on the top edge of the door, the bottom edge of the door, the first side edge of the door, and the second side edge of the door, the one or more pieces of insulation extending at least substantially along an entire length of the outer perimeter of the door;a first float positioned within the door, the first float having a first float pin that extends horizontally in a first direction from the first float and out of the outer perimeter of the door, the first float pin being configured to be received within a first opening disposed within the frame;a second float positioned within the door, the second float having a second float pin that extends horizontally in a second direction from the second float and out of the outer perimeter of the door, the second float pin being configured to be received within a second opening disposed within the frame, wherein the first float, the first float pin, the second float, and the second float pin are configured to allow the door to pivot to an open position when the first float pin and the second float pin are vertically raised out of the first and second openings;wherein the one or more pieces of insulation comprise a first piece of insulation positioned on the top edge of the door, a second piece of insulation positioned on the bottom edge of the door, a third piece of insulation positioned on the first side edge of the door, and a fourth piece of insulation positioned on the second side edge of the door;wherein the third piece of insulation includes a first insulation opening dimensioned to allow the first float pin to be raised and lowered vertically within the first insulation opening, wherein the first insulation opening is covered by a first flap positioned between the first float pin and an exterior side of the structure, and further covered by a second flap positioned between the first float pin and an interior side of the structure, wherein the first flap and the second flap are configured to at least partially prevent air from passing through the first insulation opening; andwherein the fourth piece of insulation includes a second insulation opening dimensioned to allow the second float pin to be raised and lowered vertically within the second insulation opening, wherein the second insulation opening is covered by a third flap positioned between the second float pin and the exterior side of the structure, and further covered by a fourth flap positioned between the second float pin and the interior side of the structure, wherein the third flap and the fourth flap are configured to at least partially prevent air from passing through the second insulation opening. 2. The flood vent of claim 1, wherein the one or more pieces of insulation extend along the entire length of the outer perimeter of the door. 3. The flood vent of claim 1, wherein the one or more pieces of insulation comprise a single piece of insulation positioned on the top edge of the door, the bottom edge of the door, the first side edge of the door, and the second side edge of the door. 4. The flood vent of claim 1, wherein the one or more pieces of insulation are attached to the outer perimeter of the door using an adhesive. 5. A flood vent, comprising: a frame forming a fluid passageway through an opening in a structure;a door pivotally mounted to the frame in the fluid passageway for allowing a fluid to flow through the fluid passageway, the door having two opposing faces, the two opposing faces comprising a first face and a second face, the first face being positioned to face a location exterior to the structure and the second face being positioned to face a location interior to the structure, the first face being separated from the second face by a thickness of the door;a first float positioned within the door in a location in-between the first face and a second float along the thickness of the door, the first float configured to allow the door to pivot in a first direction; andthe second float positioned within the door in a location in-between the second face and the first float along the thickness of the door, the second float configured to allow the door to pivot in a second direction. 6. The flood vent of claim 5, wherein: the first float is further positioned within a first chamber within the door;the second float is further positioned within a second chamber within the door; andthe first chamber is not in fluid communication within the door with the second chamber. 7. The flood vent of claim 5, further comprising: a third float positioned within the door in a location in-between the first face and a fourth float, the third float configured to allow the door to pivot in the first direction; andthe fourth float positioned within the door in a location in-between the second face and the third float, the fourth float configured to allow the door to pivot in the second direction. 8. The flood vent of claim 5, wherein: the frame includes a baseplate that extends vertically into the fluid passageway;the first float includes a first blocker configured to extend vertically below a top portion of the baseplate; andthe second float includes a second blocker configured to extend vertically below the top portion of the baseplate. 9. The flood vent of claim 5, wherein: the door has an outer perimeter defined by a top edge of the door, a bottom edge of the door, a first side edge of the door, and a second side edge of the door; andthe flood vent further comprises one or more pieces of insulation positioned on the top edge of the door, the bottom edge of the door, the first side edge of the door, and the second side edge of the door, the one or more pieces of insulation extending substantially along an entire length of the outer perimeter of the door. 10. The flood vent of claim 5, further comprising one or more pieces of insulation extending at least substantially along an entire length of an inner perimeter of the frame.
