Installation of the One World Trade Center antenna is now complete with the addition of a 408-foot, 758-ton glass-enclosed spire. Oldcastle BuildingEnvelope supplied the glass panels for the spire, which are treated with the EnduroShield glass protection coating on the exterior. EnduroShield chemically bonds to the glass substrate, protecting the surface against staining and etching, company officials report.
