Traditionally, insulating glass units used a metal double glazing spacer bar to separate the two panes of glass. Typically made from aluminium, these metal spacer bars were highly conductive and facilitated heat loss rather than preventing it.
Warm edge double glazing spacer bar systems were developed to overcome the challenges of using aluminium and help prevent heat transfer and condensation on insulating glass units. We launched our first Super Spacer warm edge spacer bar in 1989.
Super Spacer is a non-metal, pre-desiccated, structural foam spacer system, which provides excellent perimeter insulation for sealed glazing units, whilst significantly simplifying insulating glass production.
Creating insulating glass units with our warm edge Super Spacer bar removes a significant amount of labour from the manufacturing process. This streamlines and enhances the production line and improves productivity. The warm edge Super Spacer bar is less labour intensive as it doesn’t need to be cut into bar length form. It doesn’t need to have a PIB primary seal applied and it doesn’t need to be filled with desiccant either.
We offer three entry levels for warm edge Super Spacer bar production, with proven equipment choices selected from several leading manufacturers. Whatever your production levels and budget, we’ll have a Super Spacer bar solution to suit.
Window spacers are essential components in double-glazed units, maintaining the gap between two glass panes and providing structural support and thermal insulation.
Traditionally, metal spacer bars made from aluminum were used, but they facilitated heat loss. Modern solutions like Super Spacer® utilize non-metal, foam materials to enhance insulation and reduce condensation.

Super Spacer passes EN1279 Part 2 and Part 3; a legal requirement for all sealed insulating glass unit manufacturers in the UK. We’ve also subjected the warm edge spacer bar system to rigorous testing worldwide, to meet our customers’ needs internationally. Super Spacer is proven to withstand temperatures from -40° to 85°C – well beyond any temperatures we experience in the UK.
From improving energy efficiency to enhancing the productivity of manufacturing insulating glass units, our Super Spacer warm edge technology delivers many great benefits.

94% of energy loss through a window using an aluminium spacer system occurs at the edge of the glass. This is due to the highly conductive nature of the metal used. Over 950 times less conductive, our warm edge Super Spacer bar is the ideal solution to achieve energy-efficient windows. It also blocks heat loss and notably reduces energy costs. Super Spacer windows reduce window U-values by up to 0.2W/m2K. This allows windows to achieve the highest Window Energy Ratings possible.
Our Super Spacer warm edge spacer bar delivers unrivalled product quality and has consistently been shown to outlast other dual seal systems by 2½ times. Long-lasting quality is our guarantee and at Edgetech we stand behind our best-in-class products with our 40-year performance guarantee.
Super Spacer warm edge spacer bar systems take on the appearance of the colour of the profile into which it is glazed. For example, if Super Spacer is glazed into a white profile, the spacer bar will reflect white. This unique feature eliminates the need to stock a wide range of different colours and simplifies ordering and stock control, making for easy identification.

A spacer on a double-glazed unit refers to a component that helps maintain the gap between the two glass panes in a double-glazed window or door. It is typically a thin, rectangular strip made of materials such as aluminum, stainless steel, or thermally insulating materials like foam or rubber.
The primary purpose of a spacer is to create an insulating barrier and provide structural support for the double-glazed unit. The spacer is placed along the edges of the glass panes and forms a sealed space between them, known as the “insulating glass unit” (IGU). This space is typically filled with insulating gas, such as argon or krypton, which further enhances the insulating properties of the unit.
Find out moreThermal spacer bars, like those offered by Edgetech in our Premium range, are considered worth it for several reasons. They are designed to enhance the thermal performance of windows, which can lead to significant energy savings by reducing heat loss. These spacer bars help in maintaining a consistent temperature at the edge of the glazing unit, thereby reducing condensation and improving the overall comfort within a room. Additionally, by improving energy efficiency, they contribute to a reduction in heating costs and environmental impact.
