The Steel Window Institute (SWI) is celebrating 100 years. Officials for the institute say they’re proud of its century-long efforts to serve door and window manufacturers, while promoting steel and educating the public.

“The prominence and use of steel windows and doors are rooted in history, and they have long been recognized as the premier solution for residential, commercial, institutional, government, and healthcare buildings,” says Randy Manitta, SWI chair.
