Super Spacer™


What is warm edge technology?

Super Spacer corner with callouts

Warm Edge Technology refers to the type of spacer material used to separate the panes of glass (or glazing) in an insulating glass window unit. If the material is less conductive than a conventional aluminum spacer at the edge of the glass, it is said to be warm edge. Most newer window spacers are less conductive and outperform aluminum. But there’s still one small problem – they may contain some kind of metal, which is highly conductive.All of Quanex’s spacer products are considered to be low-conductivity, warm edge spacer products that effectively block the heat escape path and provide some of the best thermal performance and durability in the industry.
Windows that last

Long-Term Durability = Sustainability
When the elements come knocking, windows made with Quanex’s warm edge spacer technologies will more than meet the challenge.

Windows are constantly exposed to temperature changes, UV ray bombardment, barometric pressure changes and wind load. Rigid spacers containing metal don’t allow for the natural expansion and contraction that must occur in the insulating glass unit to offset the effects of these pressures on the glass. The results are stress cracks that eventually lead to seal failure. Windows made with flexible warm edge technologies develop far fewer stress cracks than windows made with rigid spacers.

If only the strong survive, Quanex spacers will outlast the rest.
