First podium glass installed at One World Trade Center
February 11th 2013
At ground level the specialized glazing provides one of One World Trade Center's most striking design features. More than 4000 glass fins, each measuring 13 feet 4 inches by two feet, will be positioned at varying angles in a regular pattern over the podium's 186 foot height. In combination with a reflective coating, they refract and transmit light to create a dynamic, shimmering glass surface. Work has now commenced on the installation of the glass, and will continue over the coming weeks.
