Great Glazing: PNC Legacy Project, Lantern Building
Photos by Edge Studio and PNC.
The basics: PNC Bank transformed Pittsburgh's Liberty Building into the modern, glass-clad Lantern Building. The 800-square-foot building is part of the PNC Legacy Project that celebrates the city's history—its culture, commerce and community, according to the company. The glass tower, with almost 1,600 square feet of channel glass, is topped by a green roof designed to naturally cool the building, lower energy consumption, and address storm water management.
The glass and systems: Exterior, vertical, curtain wall/double glazed project with 1,580 square feet of Lamberts channel glass. The five stacked openings are filled with tempered P26/60/7 Rough Cast as the outside plank, TIMax fiberglass thermal insulation, and Low E-coated P26/60/7 Rough Cast as the inside plank. All tempered Lamberts channel glass is SGCC-certified tempered and is 100 percent heat soak tested. The framing system is BWS SF60 in clear anodized finish.
