A mullion structure for enclosing sun spaces consisting of a system of straight and curved beams for supporting transparent plastic panels. The beams have cross-sectional configurations presenting end flanges which facilitate end-to-end and/or perpendicular attachment and side flanges presenting rabbets for receiving and enclosing the edges of the panels. Elongated spars having longitudinally extending rabbets are formed by joining the curved beams together in end-to-end relationship. The spars are connected to a host structure using a torsion relieving system which is made up of a torsion beam extending perpendicularly from the spar and a load bearing plate attached to the host structure. The spars are laterally flexible so that the panels may be inserted into the rabbets and flexed to assume the shape of the spars after the spares are secured to the host structure. All operations necessary for erecting the structure may be conducted from inside the space being enclosed.

A beam member for supporting sheets of construction material comprising: an elongated, generally planar, central web element, said web element having longitudinally spaced opposite ends and laterally spaced, longitudinally extending opposite edge portions; an outer flange member rigidly connected to the web element at each of its said edge portions, each of said outer flange members extending longitudinally of the web element along the corresponding edge portion and transversely outwardly away from the web element; at least an inner flange for each of the outer flange members, each inner flange being rigidly connected to the web element at a location between the outer flange members and extending longitudinally thereof from one of the ends of the web element to the other, each inner flange also extending transversely outwardly away from the web element to present an outer edge and being disposed in laterally spaced, generally parallel relationship relative to a corresponding outer flange member to present an elongated rabbet therebetween that is open at each end and which extends longitudinally of the web element for receiving the edge of a sheet of construction material; and an end flange extending laterally across the web element between the inner flanges at least one end of the web element in a position which does not cover the open ends of the rabbets, said end flange being rigidly connected to the web element and extending transversely outwardly away from the web element.
