Double glazing cuts heat loss, heat gain and noise. Retrofitting a pane to existing frames is far cheaper than full window replacement, though replacement with uPVC frames performs best. Prioritise the rooms you use most.
Ways to save
- Retrofit a second pane to existing frames to get most of the benefit for far less than full replacement.
- Do the rooms you use most, or the noisiest/sunniest windows, first if budget is tight.
- Compare aluminium versus uPVC frames, uPVC insulates better but costs more.

What a double glazing retrofit costs in Hobart
A double-glazing retrofit in Hobart is costed by the number and size of the windows and the method, because the choice runs from a secondary pane inside the existing window up to a double-glazed unit or a full window replacement, so the window count and the method lead the figure. A few secondary panes are cheaper, while replacing many large windows with new units costs much more, so the number, the size and the method drive the price.
Hobart's cold, damp climate makes double glazing one of the highest-value upgrades, because the long, cold winters mean a single-glazed window loses a lot of heat and sweats heavily with condensation that feeds mould, so a second pane makes a real comfort and health difference. A colonial or weatherboard home's single-glazed sashes are common candidates, and secondary glazing keeps a heritage window. Island freight across Bass Strait can add to a specialty unit. The small market can keep the retrofit firm.
