Abstract: A demountable wall system is disclosed in which panels are removably connected to H-shaped metal studs. The principal structure of the panel is provided by a wallboard having a width less than the modular spacing between studs. Sheet metal mounting strips are adhesively secured along the opposite edges of the wallboard and are positioned with respect to each other so as to provide the assembled panel with an exact modular width. Each mounting clip includes a connector portion which releasably secures the panels to the studs and a finish portion which extends along but is spaced from the side edges of the wallboard. A facing sheet of flexible sheet material is laminated to the forward face of the wallboard and extends across the gap between the finish portion of the mounting clips and the wallboard to hide such gap. The facing sheet then extends back along the finish portion and is provided with an edge positioned where it is not likely to be loosened during the handling and assembly of the panels.

Abstract: A window system for demountable walls is disclosed which eliminates the necessity of custom-sizing of windows to compensate for variations in floor-to-ceiling spacing. The window system provides jacking means mounted on the lower window frame member which are operable to adjust the height of the window from the floor to compensate for variations in floor-to-ceiling spacing. A floor trim assembly includes cover plates which extend up and over the lower framing member and jacking system to obscure both from view. Such cover plates rest on the floor to provide a uniform height lower window trim that follows the floor line. A baseboard and upper trim system extends uniformly along the window and adjacent wall panels to provide an integrated window and wall system. The side framing members connect to sheet metal wall studs for additional strength and enclose the adjacent stud in instances in which windows are mounted adjacent to each other.
