Quanex Celebrates 35 Years of Warm Edge Excellence

It didn’t take long for ‘warm edge’ to become common industry lingo and a staple in energy-efficient window designs.This game-changing, warm edge technology improved condensation resistance and provided a warmer edge of glass.



The concept of reducing thermal conductivity at the edge seal for improved thermal performance was revolutionary. So much so that it inspired further innovations, including the introduction of Super Spacer^®, the industry’s first structural, foam-based spacer in 1989 and, more recently, the Dura Spacer platform, which includes Duralite^®.



“The last 35 years have brought much advancement in IG systems – and many of the technologies have been tied to the individuals and companies that now make up Quanex Building Products,” said George Wilson, general manager, Insulating Glass Systems, Quanex Building Products. “To this day, we take pride in being innovators. We are always striving to help our customers find the next best thing that will improve performance and allow them to operate more efficiently. It’s ingrained in our history and will continue to be part of our future.”



Throughout 2014, Quanex will celebrate 35 years of warm edge excellence, including the next generation Dura Platform spacers, and 25 years of Super Spacer.
