Nov 02, 2024

ThermoLite Inc., a manufacturer of insulated glass, announced that it is celebrating its 50-year anniversary.

“In our 50th year, we are stronger than ever and have adapted exceptionally well to the ever-evolving window and glass manufacturing landscape,” says President John Mesko. “I am very proud of the state-of-the-art vinyl window and glass products we provide our customers. I am equally proud of ThermoLite’s loyal employees that we interact with daily.”

ThermoLite was founded in 1974 by Joe Mesko Sr., and three of his sons—Joe, Gary and George—as a vertically integrated supplier of insulated glass. The launch of ThermoLite 50 years ago enabled Mesko Glass to better control the quality and timely delivery of insulated glass to better serve their growing customer base.

Today, through its corporate headquarters and manufacturing facility, both located in northeast Pennsylvania, ThermoLite produces vinyl windows in various sizes and shapes, and also distributes sliding patio doors. ThermoLite provides vinyl windows and insulating glass for homes and businesses and coordinates with contractors and architects throughout a 150-mile multi-state radius of Scranton, Pennsylvania.
