Glazing

Anneled glass is supplied as standard in Jason Fixed Windows range. Other upgrade options include:

  • Low E
  • Double Glazing

Learn more about these glass types here.

Low E
To improve energy efficiency further, consider Low E energy efficient glass to reduce the transfer of heat or cold through the glass. Your home will stay warmer in the winter and cooler in the summer. Low E glass is like insulation panels for your home.

Double Glazing
Traditional window glazing consists of a single sheet of glass. Double glazing consists of two panels of glass in a sealed unit separated by a layer of air or argon gas. The Jason Double Glazing Range uses argon gas to create a more effective insulation break. This greatly reduces both heat flow and thermal conductivity through the window. The thermal benefits of double glazing make it ideal for rooms where greater control of heat gain or loss is required.
