The Tropical Rainforest at the National Aviary is an icon to Pittsburgh residents and bird enthusiasts alike. That’s why Vitro Architectural Glass (formerly PPG Glass) is proud to preserve the Aviary’s identity as it supplies 19,600 square-feet of Starphire Ultra-Clear® glass, featuring AviProtek® bird-friendly Velour acid-etched finish by Walker Glass. In this video, WTW Principal, Aviary Board of Trustees Member and Volunteer Tom Wiley discusses the history of the exhibit, its cultural significance and the positive attributes that bird-friendly glass provides.
