a first panel frame of a plurality of panel frames rotatably coupled together and movable, the first panel frame comprising a ledge and defining an opening, the ledge extending continuously along a majority of a longitudinal length of the first panel frame, wherein the ledge is cantilevered outward from a proximal end of the ledge and free of a vertical extension at a distal end of the ledge, the opening extending across a majority of an area defined by an outer perimeter of the first panel frame, wherein a bottom surface of the ledge extends perpendicularly outward from the first panel frame, wherein the bottom surface of the ledge is spaced apart from a bottom edge of the first panel frame in a direction opposite a direction in which the bottom surface faces, and wherein a top surface of the ledge is disposed on an opposing side of the ledge from the bottom surface, wherein the first panel frame comprises a bottom frame member, wherein the bottom frame member is formed as an aluminum extrusion;
a sheet of material having a rear surface and an opposed front surface, the rear surface coupled to a front surface of the first panel frame such that a bottom edge of the sheet rests on the ledge, wherein no portion of the first panel frame contacts the front surface of the sheet such that the front surface of the sheet is unobstructed;
a second panel frame of the plurality of panel frames, the second panel frame comprising a top frame member having a front surface, wherein the sheet of material coupled to the first panel frame is substantially entirely disposed outward of the top frame member of the second panel frame in a direction the front surface of the top frame member of the second panel frame faces; and
