Super Spacer® — The Flexible, Warm-Edge Spacer for Modern Glazing
Introduced by Edgetech Europe in 1989, Super Spacer® was the world’s first metal-free structural foam spacer system for insulating glass units (IGUs), pioneering the development of warm-edge technology. Warm-edge spacers are designed with significantly lower thermal conductivity than traditional aluminium spacers, reducing heat transfer around the perimeter of the window and improving its overall thermal performance.
For IGU manufacturers, Super Spacer® offers significant performance and productivity advantages:
✅ Superior thermal performance — As one of the most thermally efficient spacer systems available, Super Spacer® supports modern window and facade construction driven by increasingly stringent building standards and growing energy-efficiency requirements.
✅ Greater design flexibility — Suitable for rectangular, curved and irregularly-shaped IGUs for residential windows and doors, as well as commercial facades and curtain walls, enabling IGU manufacturers to meet diverse project specifications.
✅ Faster, simpler IGU production — Supplied on easy-to-use reels, Super Spacer® eliminates the need for cutting to size, bending, desiccant filling, spacer frame assembly and manual application of polyisobutylene (PIB) sealant, reducing labour requirements and shortening lead times.
✅ Better unit quality and consistency — The flexible spacer follows the contours of the glass for precise application, particularly on multi-pane and shaped units. A streamlined application process reduces opportunities for human error, supporting repeatable production and consistent unit quality.
✅ Lifespan of more than 40 years — Super Spacer® is designed to withstand prolonged UV exposure, temperature extremes, pressure fluctuations and wind loads, for long-term edge seal durability and performance beyond typical IGU warranty periods.
✅ Proven over 30 plus years in service — Trusted worldwide and installed in millions of buildings, Super Spacer® has a proven track record across varying climatic conditions and demanding architectural applications.
