Abstract
Abstract In a roof beam for a conservatory roof, an upper capping has two sides and has gasket material attached to inwards edges of inwards returns of the sides so as to be substantially hidden by those returns, for sealing on glazing panels supported on glazing bars. Those returns are connected to the sides by lines of weakness, whereby those returns can reflex.

Claims Analysis
Total Claims: 28
Claim 1
Independent Claim
107 words
A roof beam for use in constructing conservatory roofs, said roof beam comprising a glazing bar and an upper capping having gaskets along edges of the upper capping for sealing on a glazing panel to be supported by the glazing bar, and means for locating the upper capping on the glazing bar, wherein the upper capping has two sides stepped inwardly and forming inwards returns having inwards ends, wherein the upper capping has gasket material on the inward ends, and wherein the inwards returns are connected to the sides of the upper capping by lines of weakness allowing the inwards returns to flex relative to the sides.
Claim 2
Dependent Claim
107 words
A roof beam for use in constructing conservatory roofs, said roof beam comprising a glazing bar and an upper capping having gaskets along edges of the upper capping for sealing on a glazing panel to be supported by the glazing bar, and means for locating the upper capping on the glazing bar, wherein the upper capping has two sides stepped inwardly and forming inwards returns having inwards ends, wherein the upper capping has gasket material on the inward ends, and wherein the inwards returns are connected to the sides of the upper capping by lines of weakness allowing the inwards returns to flex relative to the sides.
