Edgetech celebrates 35th anniversary of flagship Super Spacer® product innovation

Edgetech, leading innovator in spacer technology and a Quanex company, is celebrating the 35th anniversary of its flagship product, Super Spacer®, the world’s first foam warm-edge spacer bar.

Introduced in 1989, Super Spacer revolutionised the fenestration industry by offering superior thermal performance and productivity compared to traditional metal spacers.

Super Spacer’s innovative foam construction boasted a staggering 950 times lower thermal conductivity compared to the mainstream metal spacers mostly used at the time. This significantly reduced heat loss at the crucial window edge, a major factor in overall window energy efficiency.

Over the past 35 years, Super Spacer has become the industry leader in warm-edge spacer bars, and the market has experienced a shift with warm-edge technology now used in the majority of units, thanks in no small part to Edgetech’s tireless campaigning.

And it’s innovative design is still leading the market today.

Used in iconic structures worldwide, from the renovation of the Eiffel Tower to Dubai’s Museum of the Future, Super Spacer empowers architects and manufacturers to achieve ambitious projects that prioritise energy efficiency.

Super Spacer enables faster window production with less labour, translating to significant cost savings. The latest high-speed automated Super Spacer lines can produce 23.5% more units with just three employees compared to a nine-person line using rigid box warm-edge spacers.

Super Spacer reduces heat loss, condensation, and noise transmission, creating a more comfortable and energy-efficient living environment.

What’s more, Super Spacer’s resilience has been rigorously tested, withstanding extreme wind speeds and temperature fluctuations.

“We’re incredibly proud of Super Spacer’s 35-year legacy,” says Chris Alderson, President of European Fenestration at Quanex.

“In an era of increasing focus on sustainability and energy efficiency, Super Spacer remains a vital tool for architects, builders, and homeowners alike, and as a company we’ll never stop challenging ourselves to create the products that propel our industry forward.”
