The UK's number one choice of warm edge technology

What is a Warm Edge Spacer Bar?

Warm Edge Technology drastically improves the energy efficiency of insulated glass units (IGUs). By using highly insulating warm-edge spacer bars, IGU manufacturers can maximise the thermal performance of their finished window products.

Why Warm Edge technology has radically altered the window market

Warm edge technology effectively improves upon the thermal performance of highly conductive aluminium spacer bars. Reducing thermal conductivity considerably, proactive IGU manufacturers are embracing Thermal Barrier technology within their designs to fully comply with commercial and residential energy codes.

Focused on energy efficiency for almost 30 years, Edgetech are pioneers in warm edge spacer bar technology; developing the world’s first flexible foam bar in 1985.

Component certified by Passivhaus, the fastest growing energy performance standard in the world, our building clients can rest assured that our glazing spacer products will significantly contribute towards energy savings, climate protection and improved levels of health and comfort.

Why choose Super Spacer?

Super Spacer was the world’s first foam warm-edge spacer bar, and thanks to years of intensive product development, it’s still the best.

Super Spacer is a non-metal, pre-desiccated, structural foam spacer system which provides excellent perimeter insulation for sealed glazing units and simplifies insulating glass production.

It’s no surprise that approximately a third of all UK IGUs are made with Edgetech warm-edge technology.
