A horizontal garage door assembly includes a plurality of panels, which are pivotally connected at adjacent side edges. A top rail receives the plurality of panels and includes a first straight portion, a curved portion, and a second straight portion. A motor is positioned at a first end of the first straight portion, a tensioning mechanism is disposed on a first panel, a gear mechanism is positioned at a second end of the first straight portion. A connecting band connects the motor, the gear mechanism, and the tensioning mechanism to form a loop along a length of the top rail. The motor drives the connecting band such that the plurality of panels moves between a closed position, in which the plurality of panels is substantially received in the first straight portion, and an open position, in which the plurality of panels is substantially received in the second straight portion.

The present invention provides a frame (10) for a sliding door which sits within a pocket, wherein the frame comprises of rigid vertical posts (20), which have channels (24) which contain a beam (22) for strengthening of the posts and allowing the fastening of plasterboard or other such wall panels to the vertical posts (20).

A panel door for traversing a curved track. The panel door includes front and back faces formed by membranes and a central area between the membranes with a core material. The back face has a plurality of openings having a set width. The openings in the back face align with channels in the central area. The channels have a width that varies along the depth or the depth of the channel extends to the opposite membrane such that a portion of the membrane is exposed by the channel.
