Windows - what to look for

Double glazing works by creating an insulating layer of gas between two panes of glass.

Retrofit double glazing is still quite expensive in New Zealand so it's worth repeating that it's not required in HomeFit as long as the home has 'good' curtains. However, double glazing is very effective at reducing heat lost through windows and will make the home significantly more comfortable. Consider retrofitting when carrying out a major refurbishment or replacing windows.

Double glazing has an inner and outer pane of glass separated by a small gap. Single glazing has only one piece of glass. Look at the edge of the window - double glazing has an obvious gap between the two panes.
