Abstract: An extruded aluminum elongated sill member is supported by a wood base member and includes a sloping top wall integrally connected to a lower base wall positioned within a recess in the wood base member. A longitudinally extending wood trim member is attached to the wood base member and cooperates with the lower base wall to define a longitudinally extending cavity which receives a vertically adjustable rail member. The sill and rail members define corresponding longitudinally extending adjacent slots, and a longitudinally extending sealing member of extruded plastics material includes opposite semi-rigid edge portions with flexible fins which are pressed into the slots. The edge portions are integrally connected by a flexible U-shaped intermediate portion which is confined between the sill and rail members and forms a rolling diaphragm for vertically adjusting the rail member while maintaining a positive water-impervious seal therebetween.

Abstract: An elongated extruded door sill member is supported by a wood base and includes a sloping top wall and a rear wall connected by integral channel portions and a thermal barrier. The channel portions and barrier cooperate to define an upwardly facing cavity, and strips of resilient closed cell foam material are mounted within the channel portions. A vertically adjustable rail member extends longitudinally within the cavity and has side flanges projecting downwardly into the foam strips to form fluid-tight continuous seals. Opposite end portions of the rail member carry pads of the resilient foam material between the flanges for engaging the strips, the channel portions and the thermal barrier to form fluid-tight seals at the ends of the rail member.

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.
