Abstract
Abstract A glazing bar used for forming a roof beam in a conservatory roof system has a generally inverted T-section. The T-section has an upstanding limb to which an upper capping may be fixed, and a cross bar with a central section and edges. The central section has an upper face defining a plane. The edges are shaped in the form of troughs extending below the central section and the plane to form a recess in the underside of the glazing bar. The central section has first parts extending at first angles way from each other and from the upstanding limb. The second parts, formed as continuous extensions of the first parts, diverge away from each other as they extend at second angles away from the first parts. The second parts form inner side walls for the troughs. The recess has outwardly extending faces formed by the inner side walls that diverge away from each other as they extend from the central section first parts.
