先进中间层解决方案部门 项目 Leatop Plaza
ADVANCED INTERLAYER SOLUTIONS
The visual appeal and brightness of the building is primarily down to the use of white ceramic glaze in over 70% of the hanging element of the overall façade. The façade also offers significant beneficial functional attributes thanks to the use of SentryGlas® ionoplast interlayer in its laminated construction.
At 303 m (994 ft), 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 159,500 m2 (1.700.00 sq ft), SentryGlas® was used over 63,000 m2 (678.000 sq ft).
Secured to the building to look like scales, the 1.95 x 4.2 m (6.4 x 13.8 ft) ceramic glazed laminated panels comprise 8 mm (5/16") HS low-iron + 1.52 (60 mil) SentryGlas®+ 8 mm (5/16") HS low-iron glass + air + 8 mm (5/16") low-iron glass. The panels exhibit a partial open-edge design, with 0.5 m (1,6 ft) of their 1.95 m (6.4 ft) width hanging out in the open. The architect took this approach for multiple reasons.
First to improve the façade's energy-saving capabilities; as the projecting façade acts as sun louver, helping to decrease energy using by 5%. Second, for aesthetic reasons, the scale façade looks white and transparent making the building brighter than any of the surrounding buildings. Finally there was a strict requirement concerning durability and delamination. Any potential panel failure would have led to the design being rejected.
SentryGlas® played a key role; as well as its compatibility with the ceramic material it has also seen deployment in many energy-saving installations around the world. Finally, its open-edge durability is very impressive, giving the architects and owners the confidence they need relating to the open edge design. According to the lead architect: "We were looking for a solution that offered enough durability for this design. And we finally found the answer in the form of SentryGlas®."
