Provided are door systems having a plurality of door panels and a frame, the door panels being movable horizontally between an extended position closing an opening in a building structure, and a folded retracted position opening the opening in the building structure. When in the extended position, the door panels interlock with each other forming a barrier to wind, dirt, dust and insects. The frame is movably attached to the building structure and when the door panels are in the extended position, the frame moves and engages the door panels with a sealing member to provide an airtight seal of the opening in the building structure.

An acoustical seal system that utilizes a sound absorbing material-based sound seal for the gap or flanking path between a closed door and the nearby surfaces (e.g., the door jam or frame and the floor). When the door is in a closed position, the acoustical seal system may leave a small gap around the door so that the door does not have to make contact with the surrounding structural components. The small gap is an air passage between the two adjacent rooms. The acoustical seal system includes a housing with one or more cavities. The housing is mounted on the sides of the door core or body or on the surrounding components such that the cavities face the small air gap when the door is in the closed position. The cavities are filled with sound-absorbing material, such as an acoustical foam, that is exposed to the air gap.

A sliding window assembly (35) including a window frame and at least two glass panes (38, 39). At least one of the glass panes (38, 39) slides within the frame between an open position and a closed position, wherein one of the edges of each pane overlaps to form overlapping edges (42, 43). First and second rails (44, 45) are connected to the overlapping edges (42, 43) and cooperate to form a seal between them in the closed position. Each rail (44, 45) is formed from a metal component (46) and a plastic component (51) that are formed separate from each other and are assembled in nesting connection. The seal in the overlap between the overlapping edges (42, 43) in the closed position of the panes (38, 39) is formed between the plastic components (51) of the first and second rails (44, 45). The metal components (51) of the first and second rails (44, 45) are spaced from contact with each other and extend to overlie outwardly facing surfaces of the first and second panes (38, 39).

The subject invention provides for a weatherstrip assembly for sealing between a frame and a closure member of a vehicle. The assembly includes a trim portion having a body and a flange extending from the body. The flange is capable of moving between an initial position and a final position. A seal extends from the body for abutting and sealing the closure member. An adhesive is disposed on the body for coupling the trim portion to the frame. The adhesive is disposed opposite the seal such that the seal extends away from the adhesive. A retaining member is selectively mounted to the flange and spaced from the adhesive for selectively engaging the frame to selectively hold the flange in the initial position relative to the frame. The retaining member is removed from the flange while concurrently moving the flange toward the final position.
