Worlds tallest tower having double skin facade. one of the most admirable project in the world. i have personally visited the site in Mar'2013 , facade was under construction and the quality of workmanship is good.
Installation bracket design is superb , thanks to structural engineer and fabrication team for such a wonderful monument or we can say engineering marvel. i can understand the intricasy of the work. Inside glass used is low iron extra clear glass , i have personally the glass factory i.e. golden glass factory.
