A well-insulated house helps you maintain optimum temperature throughout all seasons. It protects you against cold in winter and heat in summer. This way you spend less on additional heating and cooling systems which makes insulating your home a very good investment. Insulation also provides a healthy environment for your home by preventing the build up of mould.
The four main areas that you can expect heat loss is your ceilings, walls, floors, and windows. Single glazed windows (or pane of glass) has been insulating and protecting our homes for centuries, but is there anything better than glass? The answer to this is double glazed windows and doors.

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
