Abstract
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.
