Abstract: A threshold system for a door incorporating a seal and a threshold plate. The seal mounts to the door and has a flap extending therebeneath. The threshold plate has a raised inner section connected to a recessed outer section by an upstanding lip. The threshold plate disposed below the door so that the flap of the seal contacts with the upstanding lip of the threshold plate, thereby creating a seal between an outside area and an inside area. An outer deflector is mounted on the door body to deflect air and moisture away from the threshold plate and seal.

Abstract: An angulated door assembly affording reduced entry and exit time and motion therethrough. Each door is angulated relative to the adjacent walls and/or the conventional path of ingress/egress therethrough. Such an assembly configuration affords increased sealing capacity as well as convenience for the user. The door opens and closes faster by swinging less than a conventional door, which presents itself orthogonally to the path of ingress/egress. By utilizing a pair of angulated doorways, the doors self-seal against each other while providing the advantages of angulated disposition relative to the path of ingress/egress.

Abstract: An improved panel mounting system for curtain wall construction of the type comprising a plurality of transparent and non-transparent panels secured to structural millions and disposed adjacent each other wherein the panels are constructed with an outer hollow region integrally formed with structural interconnection means.

Abstract: An improved mullion for a building system. The mullion has a plurality of peripheral wall and web sections defining a load bearing structure adapted for supporting the panel in sealed engagement therewith. The mullion is roll formed from thin gauged metal and further includes an integrally formed, hollow body section having portions defining a glazing pocket therein. Structural members are adapted to be disposed within the mullion body for the engagement and structural integrity thereof. The structural members are secured to the mullion body for maintaining the hollow mullion profile under loading conditions.
