A folding screen is formed by a plurality of successively hinged, rigid, radiation-controlling planar panels supported so the screen can be opened (or extended) and closed (or collapsed). Adjacent panels are supported only at their edges, by a hinge member having symmetrical back-to-back tubular channels. The hinge member possesses sufficient rigidity to permit hinged, side-by-side coaction of the panels from a stacked, generally vertical relationship when the screen is collapsed, to an undulating planar relationship when the screen is opened, which relationship is essential if the screen is to be collapsed without binding. The screen is translatable on a pair of parallel, mono-level tracks, and operated by a flexible drive member extending along a rail and connected to the screen's leading ("lead") panel. A novel skylight includes a curb assembly, a "bubble" (or "dome") and a folding screen translatable to-and-fro below the bubble. The curb assembly is mounted on a curb provided on the roof, and the assembly includes an access panel which allows access to the folding screen housed in the assembly.
