World-class performance from the leading warm-edge spacer bar

Spacer bars separate the panes of glass in a double-glazed unit. Warm-edge spacers achieve that with modern materials that deliver exceptional thermal efficiency.

Since its invention, warm-edge has helped dramatically improve the thermal performance of buildings all over the world – and Super Spacer® has been leading the warm-edge market since 1989.

Unlimited possibilities with Edgetech’s flexible spacer bars

It’s Super Spacer’s unparalleled flexibility that’s the secret to its success. Where using rigid spacers limits you to using traditional window shapes, without expensive bending machinery, Super Spacer makes the most complex and unconventional designs possible with ease.

That’s why, when building designers want to create without restraints, it’s Super Spacer they turn to.

TriSeal™ – the ultimate in endurance

For the most demanding commercial applications, we’ve developed Super Spacer TriSeal.

Its incredible strength makes longevity issues a thing of the past, while its flexible design allows it to move with the glass itself when subjected to strong winds or changing pressures.

TriSeal has excelled in some of the most stringent testing global construction has to offer.

At Fiva Glass in Norway, for example, the product was used to create a huge glass unit weighing nearly 312kg. Then, the unit was held aloft in an extreme shear test for 15 minutes, relying solely on TriSeal’s pre-applied PIB sealant to keep it together – and once the test was finished, the two panes hadn’t moved at all.

What is the purpose of spacer bar?

The purpose of a spacer bar in a window is to create a gap between the panes of glass in double or triple glazing systems. This gap is essential for the insulation properties of the window. Spacer bars help to seal and maintain the space between the panes, preventing the movement of air and moisture. This contributes to reducing heat transfer and condensation, enhancing the thermal efficiency and overall performance of the window.
