The Chinese city of Guangzhou may have many skyscrapers, but one has been designed specifically to be a bright beacon against the often gloomy backdrop provided by the city's weather.

 At 303 m, the Leatop Plaza is Guangzhou's fifth tallest building. Of the total façade area of 159,500 m2, SentryGlas® was used
over 63,000 m2, for its strength and energy-saving capabilities.

At 303m, the Leatop Plaza is the city's fifth tallest building. It has 69 floors in total, 5 of which are below ground, 35 elevators and 838 parking spaces. Designed by a team including more than 10 design firms, the developer invested some 2 billion RMB in the project, which was finally opened in 2012. Of the total façade area of 159,500m2, DuPont™ SentryGlas® was used over 63,000m2.

The visual appeal and brightness of the building is primarily down to the use of white ceramic glaze in over 70 percent of the hanging element of the overall façade. The façade also offers significant beneficial functional attributes thanks to the use of SentryGlas® in its laminated construction.

  • Improve the façade's energy-saving capabilities, as the projecting façade acts as a sun louver, helping to decrease energy use by 5%

  • Scale façade looks white and transparent, making the building brighter than any of the surrounding buildings.

  • Met strict requirements concerning durability and delamination; potential panel failure would have led to the design being rejected.

  • Very impressive open-edge durability gives architects and owners the confidence they need relating to the open-edge design.
