Vinyl Window Biography

June 29, 2018

Although German window manufacturer Trocal introduced the first commercially viable vinyl windows in the 1950s, the technology first appeared in the U.S. in 1964, when Thermal Industries began offering a vinyl unit to the replacement window market. Vinyl windows didn’t become a player in the new construction market until the late 1980s, but growth since then has been rapid. By 2009 they accounted for about 60 percent of all window sales.
