Recent renowned projects like the 50storey Manulife Tower, the 62storey Cheung Kong Center, the 80storey “Center”, the 88storey International Financial Center, and a number of recent residential buildings exceeding 60storey tall, are without exception, using curtain wall as their external envelope. Using thin wall as external envelope for tall buildings has always been a challenge to designers and builders, in particular in terms of cost, energy, watertightness, installation, dimensional and structural stability, interfacing arrangement with other building ponents and maintenance etc. Making use of the Hong Kong’s experience, the writer wish to highlight some local practices and summarize how such thin wall systems are designed and installed. USING CURTAIN WALL IN BUILDIGNS OF HONG KONG Highrise buildings started to spring up in the skyline of Hong Kong since the 1970’s in parallel with her economic takeoff from a traditional manufacturingbased industrial economy and transforming herself into an worldrenowned international financial centre. Highrise buildings by that time were concentrated in the mercial districts like Central in the Hong Kong Island and Tsim Sha Tsui on the Kowloon Peninsula side. The first generation of buildings using whatsocalled a curtain wall system can hardly be described as a full system which is usually of proprietary design. The pioneer systems were just external fa231。ade/walling designed by local architects and with materials supplied by local manufacturers. The mon systems used by that time were in majority sticktype, spandrel and cover, or unitinframe systems, constructed of aluminum sections, sometimes incorporated with large areas of stone slabs to cover up solid walls. They were popular due to their highly adaptability, low cost, easy to designandinstall nature. More deluxe mercial buildings were built in the late 70’s as the economy of Hong Kong growing hotter and hotter. Developers tended to request for systems with higher performance as the external envelop for their buildings, in terms both of appearance, material, construction and maintenance concerns. Due to the relative lack of experience at that stage, the performance of these second generation curtain wall systems (from late 70’s to mid 80’s) could still hardly described as satisfactory. Problems like seepage, staining, deformation, deterioration and rapid aging of the jointing materials, were very mon to many walling cases, often to a condition that made repair and maintenance almost impossible. The replacement of these walling systems not only costly, but also created great disruption to the normal utilization of the building users, and at the same time badly lowered the property value of the entire premises. The third generation of curtain wall systems roughly started in the mid/late 80’s, by the time Hong Kong was experiencing her economic climax before the handing over of her sovereignty back to China in 1997. Acmodated experience in the application of curtain wall systems in highperformance buildings contributed solidly in the process of perfecting these systems. Throughout the period, the design and production teams, as well as the manufacturers and the engineering supporting teams, were growing more mature in the mastering of the local situation and market. Most problems appeared in the previous cases have been much effectively taken care of. Systems of this generation are in general much more satisfactorily received by most users. WHAT IS A CURTAIN WALL Metal and glass curtain wall systems have found growing favour in modern architecture. They are easily distinguished from other types of claddings by their thin mullions of horizontal and vertical metallic bars surrounding an all glass or metal panel. The curtain wall system has evolved rapidly over the last two decades, especially with respect to weather control performance. The early systems presented frequent rain peration problems。 water stain patches would form on the outside or condensation on the inside mullion surfaces。 glazing seals were sometimes pumped out of the rabbet of sealed double glazing window units. However, most of these difficulties were eventually overe with improved detail design of the system ponents. Today, most curtain wall manufacturers offer a quality product line of ponents which can be used to create one of the best overall exterior wall systems. A curtain wall system is a lightweight exterior cladding which is hung on the building structure, usually from floor to floor. It can provide a variety of exterior appearances but is characterized by narrowly spaced vertical and horizontal caps with glass or metal infill panels. These systems provide a finished exterior appearance and most often a sem
