Double Glazing

Low conductivity double glazing gases for energy efficient windows

Double Glazing

Energy efficiency of windows depends on the:

  • Glass type
  • Frame design and material
  • Double or triple glazing
  • Cavity size
  • Cavity filling gas.
With new replacement window legislation requiring the lowering of centre pane ‘U’ values, cavity filling window gases can greatly improve the energy efficiency of windows.

Low Thermal Conductivity

The thermal conductivities of the double glazing gases Argon, Krypton and Xenon are much lower than air, meaning they are efficient insulators and thus they are both ideal for keeping U-values low in sealed double and triple glazed units, either in combination with each other or with air.

As these are inert gases with low conductivity, they can also be used to up-rate the thermal performance of sealed units without adversely reacting with the high tech desiccants and sealants used in today's state-of-the-art glazing units.

Gas Specialist

BOC is a specialist supplier of Argon, Krypton and Xenon gases for sealed unit window manufacturers, and our products can be supplied in a range of cylinders sizes or in liquid tanks for large requirements.

Bespoke Windows

Bespoke window applications requiring a higher WER rating may require Window Grade Krypton or Xenon gases and these can be sourced in cylinders either as pure gases or as gas mixtures.
