Windows are a key component in restoration projects. The Union Station in Winston-Salem, North Carolina, was no exception. Originally designed by Fellheimer & Wagner, it was built in the 1920s when Winston-Salem was the largest city in North Carolina. It represented the level of growth and industry at that time.

In later years, the station was shut down and sold. The building itself ultimately fell into disrepair and desperately needed to be restored when the city bought it back. As part of the restoration, the City of Winston-Salem sought to improve the thermal performance of the building. With over 1500 windows throughout the station, improving them became a key feature to consider when looking at thermal control.

Installing contemporary IGUs would require that the existing metal windows get ripped out entirely. To avoid this, Walter Robbs Callahan & Pierce Architects had planned to use interior storm windows improving performance while preserving the look of the original windows on the outside.

With Pilkington Spacia™ VIG technology, they could get the desired thermal performance without having to add storm windows or having to rip out the historic metal windows. At ¼” thick, and with the performance values of a contemporary IGU, Pilkington Spacia™ is an ideal fit for many restoration projects.
