A system for impeding air or liquid penetration through an entry into the interior of a structure includes a door mounted to a door frame. The door frame includes at least one integral cavity. The system also includes a dual-sealing system between the door and the door frame. The dual-sealing system includes an inner seal and an outer seal. A drainage cavity is defined by a region bounded by the inner seal, the outer seal, the door, and the door frame. A gap is formed in the outer seal that permits equalization of pressure of the cavity with external atmospheric pressure.

1. A system for impeding air or liquid penetration through an entry into an interior of a structure, the system comprising: a door mounted to a door frame, the door frame comprising at least one first cavity formed therein;a dual-sealing system between the door and the door frame, the dual-sealing system comprising an inner seal and an outer seal;a second cavity defined by a region bounded by the inner seal, the outer seal, the door, and the door frame, the second cavity extending around a perimeter of the door;a first weep hole formed in a vertical member of the door frame that permits liquid within the first cavity to flow into the second cavity only under the influence of gravity; andwherein a gap is formed in the outer seal that permits equalization of pressure of the second cavity with external atmospheric pressure. 2. The system of claim 1, comprising a second weep hole formed in a threshold member of the door frame that permits liquid within the second cavity to flow into the first cavity. 3. The system of claim 2, wherein the threshold member comprises a groove that channels liquid from the first weep hole to the second weep hole. 4. The system of claim 3, wherein the threshold member comprises an outer third weep hole that channels liquid to an exterior of the door frame, the outer third weep hole interoperably coupled to the second weep hole. 5. The system of claim 1, wherein the gap reduces deformation of a gasket forming at least part of the outer seal. 6. The system of claim 1, wherein the door comprises a durable and rust-resistant extrudable material. 7. The system of claim 1, wherein: the inner seal comprises a gasket;the gasket comprises a generally J-shaped member; andthe generally J-shaped member forms at least one of a liquid-resistant and air-resistant seal responsive to a force applied against the gasket by the door. 8. The system of claim 7, wherein the gasket deforms responsive to being rolled over by a wheelchair. 9. The system of claim 1, comprising at least one unsealed hinge that channels liquid via the first cavity to the first weep hole. 10. The system of claim 1, wherein the door frame comprises a durable and rust-resistant extrudable material. 11. The system of claim 1, wherein the inner seal comprises: a first gasket fixed along a length of an exterior side of a door-jamb stop portion of the door frame; anda second gasket extending upward from an upper surface of a threshold member of the door frame. 12. The system of claim 11, wherein: the second gasket comprises a compressible gooseneck portion facing towards an exterior of the door. 13. The system of claim 2, wherein the threshold member comprises a groove spanning an upper surface of the threshold member and located outward of the inner seal. 14. The system of claim 13, wherein the second weep hole is formed in the groove, the second weep hole allowing liquid to drain into the first cavity. 15. The system of claim 1, wherein the outer seal comprises a sweep gasket. 16. A method of using the system for impeding infiltration of air or liquid through a structure entry or claim 1, the method comprising: providing the door mounted to the door frame comprising the first cavity;providing the inner seal and the outer seal;wherein the second cavity is defined by a region bounded by the inner seal, the outer seal, the door, and the door frame;equalizing the second-cavity pressure with the external atmospheric pressure via the gap formed in the outer seal; anddraining liquid from the first cavity via the first weep hole formed in the door frame and interoperably coupled with the first cavity. 17. The method of claim 16, wherein the draining step comprises liquid flowing from the first cavity of the vertical member into the second cavity through the first weep hole formed in the vertical member of the door frame. 18. The method of claim 17, wherein the draining step comprises liquid flowing from the second cavity to into the first cavity of the threshold member of the door frame though a second weep hole formed in the threshold member. 19. The method of claim 18, wherein the draining step comprises channeling liquid from the first weep hole formed in the vertical member to the second weep hole formed in the threshold member via a gasket mounted to the threshold member of the door frame and forming at least part of the inner seal. 20. The method of claim 19, wherein the draining step comprises liquid flowing exterior to the structure entry via an outer third weep hole interoperably coupled to the weep hole formed in the threshold member. 21. The method of claim 16, wherein the equalizing step reduces deformation due to external air pressure of a gasket forming at least part of the outer seal. 22. The method of claim 16, wherein the inner seal comprises a gasket comprising a generally J-shaped member that forms a liquid-resistant and air-resistant compression seal responsive to an external force against the gasket by the door. 23. The method of claim 22, comprising the gasket deforming responsive to being rolled over by a wheelchair. 24. The method of claim 16, wherein the inner seal comprises a gasket fixed along a full length of an exterior side of a stop of the door frame and a gasket extending upward from an upper surface of a threshold member of the door frame. 25. The method of claim 16, wherein the inner seal comprises a compressible gooseneck gasket facing toward an exterior of the structure entry. 26. The method of claim 16, comprising a threshold member of the door frame, the threshold member having formed therein a groove spanning an upper surface of the threshold member and located outward of the inner seal.
