The Architectural Glass Institute published a case study recently featuring our replacement of historic windows at the c. 1920s Alden Park Apartments in Philadelphia, a National Historic Register site. The project, as part of a massive renovation by L3C Capital Partners with architect BartonPartners and GC Briarwood Construction, included 6,688 deteriorated steel windows being retrofitted with carefully engineered, energy-efficient replicas manufactured by Graham Architectural of York, Pennsylvania. Our installation crews achieved completion in just 14 months, four months ahead of schedule. Read the full case study here.
