Curtain walling is the generic name given to metallic lightweight cladding or glazed cladding systems that are directly supported by a structural frame. In some cases, a stone veneer or large tiled fascia may be attached to give the appearance of a more monolithic cladding system.
Curtain wall systems are an assembly of factory-made components which are either made up into panels in the factory and the interlocking units brought to site and installed (unitized curtain walling) or brought to site as components and assembled on the building (stick curtain walling). Stick curtain walling is more often used on low-rise buildings and in relatively small areas because external access is required to the building elevations, e.g. from scaffolding or wall-climbing work platforms. Unitised curtain walling can be designed to be installed without using the main crane and this method is favoured on high-rise buildings. Methods used are a mini-crane mounted on the office floor or a hoist mounted on a temporary rail round the perimeter of the building.
