Super Spacer® introduces no-metal warm edge technology to windows, helping to deliver windows of the highest standard. Super Spacer® is a no-metal, pre-desiccated, structural foam spacer system. Its award winning, patented Thermal Set Spacer (TSS) technology gives the ultimate in high performance spacer systems. Since it was first introduced in 1989, Super Spacer® has become the dominant force in thermally efficient spacer systems.

Super Spacer® has 100% memory and allows for expansion and contraction, a major cause of fractures in conventional sealed units. In accelerated testing Super Spacer® has been shown to last over twice as long as other dual seal systems and five times longer than single seal systems.

Cleartherm Glass Sealed Units have achieved EN1279 Part 2 and Part 3 – a legal requirement for all sealed unit manufacturers. In order to meet the demands of our customers worldwide, here at Cleartherm Glass Sealed Units, we subjected Super Spacer® to rigorous testing to meet the demands of the international market.  Super Spacer® is proven to withstand temperatures from -15° to 125° well beyond the temperature variances we experience in the UK.
