25th Anniversary of PPG's STARPHIRE Glass Traces History to Fallingwater
Frank Lloyd Wright’s home, Fallingwater, is known for many architectural firsts. One of the least celebrated may be the architect’s use of whitewater glass, which incorporated a proprietary low-iron formulation developed by PPG in the 1930s to make glass clearer and more transparent.
In 2009, the Western Pennsylvania Conservancy, owners and caretakers of Fallingwater, initiated a five-year project to replace more than 300 windows in the historic, wood-bound home with replicas fabricated from STARPHIRE® ultra-clear glass, an advanced low-iron glass that PPG introduced 25 years ago. Frank Lloyd Wright specified low-iron glass for its capacity to diminish the visual barrier between Fallingwater and its iconic creek-top setting. Starphire glass is reportedly selected by today’s leading architects to achieve a similar objective. According to PPG, Starphire glass is the clearest, most transparent commercial float glass available today, with visible light transmittance (VLT) of 91% in a standard ¼-in. thickness.
