25th anniversary of STARPHIRE glass traces history, heritage to Fallingwater

Historic home among first to feature PPG low-iron glass, precursor to STARPHIRE glass

PITTSBURGH, Aug. 31, 2015 – Frank Lloyd Wright’s 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 Industries (NYSE:PPG) in the 1930s to make glass clearer and more transparent.

In 2009, the Western Pennsylvania Conservancy, owners and caretakers of Fallingwater, honored Wright’s allegiance to low-iron glass by initiating 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.

An historic product in its own right, Starphire glass remains the clearest, most transparent commercial float glass available today – a quarter-century after its debut – with visible light transmittance (VLT) of 91 percent in a standard ¼-inch (6-millimeter) thickness.

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 commonly selected by today’s leading architects to achieve a similar objective.
