How much does double glazing cost?

Double Glazing is the most expensive as compared to retrofitting or installing secondary glazing. This involves replacing your current windows with a IGU and new frames. If your priority is to increase the insulation of your home, then this is the best option to go with as it is the most effective. On an average it will cost around $35,000 to double glaze a 100m2 home in Auckland. If you choose Low-e glass panes along with Argon gas in the cavity then the price for double glazing will go up.

Tips to reduce the cost of double glazing for your home

Different combinations of your IGU (window-panes, sealant, gas or still air and frame) will yield different R values. Some combinations will be more effective in insulating your home but not all homes need a high level of insulation. For example, if your home does not need high insulation then it is a waste to install low-e glass panes or Argon gas in the cavity which is a more expensive combination.

Reduce costs by:

  • Choose clear glass or laminated glass instead of a low-e glass for your panes
  • Opt for still Air instead of Argon gas for your insulated cavity between your glass panes
  • Choose Aluminium as your window frame

To sum up

What is Double Glazing?

Double glazing involves removing the old windows and frame. A new frame for the window is manufactured which is fitted with an Insulated glass unit. An Insulated glass unit which consists of 2 panes of glazing or glass that are parallel to eachother with a gap between them. A spacer is attached between the glass which is bonded with the the panes of glass with a sealant. This keeps the two glasses in place and provides a stable structure. This cavity between the two parallel panes of glass is filled with either Still Air or Argon gas.

What is Retrofitted Double Glazing?

Retrofitting Double Glazing involves installing an Insulated glass unit into your existing joinery or frame. An insulated glass unit has two parallel panes of glass with a gap in the middle. This gap has a spacer which is bonded to the panes with a sealant. This cavity is then filled with Still Air or Argon gas.

How much does it cost to double glaze my home?

Double glazing an average 100m2 home in Auckland will cost around $35,000.00. The cost will vary depending on the glass you choose, whether you get Still Air filled cavity or an Argon gas filled cavity. The material of the joinery/frame you choose will also affect the price.
