Abstract: An improved weathersealed door system includes a sill and a cooperating weatherseal member which has a tubular depending portion deflected by the sill in the closed position so as to provide firm surface engagement therewith. A header weatherseal member extends across the top edge of the door and is also resiliently deflected in the closed position of the door. Extending vertically along the hinge side of the door is a first hinge jamb weatherseal member which seats against the surface of the door in its closed position, and a second hinge jamb weatherseal member extends upwardly from the sill and is fabricated of highly compressible material of greater thickness than the space between the side edge of the door and the jamb. As a result, it is compressed by both the side edge of the door and the sill weatherseal member when the door is in its closed position.
