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