Trinity Glazing construct Heritage Double Glazed Units with:

  • A select cavity sizes of 4mm, 6mm, or 8mm - the wider cavity size increases the insulation of the unit
  • A select insulating inert gas - specifically designed to perform in smaller cavities
  • An inner pane of 3mm or 4mm low emissivity glass – the emissivity coating is on the inside face of the cavity and reflects the long wave radiation or heat back into the room
  • A Warm Edge Technology perimeter spacer – this improves the thermal efficiency of the window, reduces the risk of condensation, and significantly lowers the temperature differential between the edge and the centre of glass

By using and maximising the latest technology, Trinity Glazing construct Heritage Double Glazed Units with a small cavity or space between the panes. The addition of a selected insulating inert gas into the cavity ensures low U-Values that are compliant with building regulations. The U-Values of Heritage Double Glazed Units are comparable or better than U-Values in standard double-glazed units.

Heritage Double Glazed Units are constructed with a warm edge spacer to increase the U-Value, low emissivity glass to reflect the heat back into the room, and low conductive inert gas to ensure that the maximum possible insulation is obtained. Heritage Double Glazed Units utilise and maximise the latest technology to reduce the heat loss by convection, radiant heat loss, and conduction. The unique small cavity and small perimeter seal in Heritage Double Glazed Units provide the best possible insulation available today.
