again, you are discussing an industry with a culture all of it's own
take time, document the buildings you see - take pictures, take pictures of things like frames, roofs, foundations - note pest control, look closely at windows.
then - head overseas - look how new houses are built - France, maybe Finland - whilst Finland is cold and Oz hot - many same principles apply for keeping heat out and heat in
see the differences
NSW has over HALF of all new apartments with serious building defects. Why?
Cheap, shoddy.
Look very closely at the windows in Oz and the windows overseas - it's a revelation.
Oz house culture - is cheap materials, inefficient performance and very high price -----
an example -
The percentage of houses with double glazing in Australia is significantly lower compared to the UK, US, and other parts of Europe.
Specifically:
- In Australia, around 11.3% of new Class 1 dwellings (houses) included low U-value (high-performance) windows in 2022, with 10.1% including low solar heat gain coefficient (SHGC) windows[1]. These percentages are much lower than other developed countries.
- In the UK, around 87.7% of houses had full double glazing installed as of 2022[4]. This is a stark contrast to the low adoption rate in Australia.
- Similarly, in the US and New Zealand, around 80% of new houses have high-performance windows installed[3], which is vastly higher than Australia's 10-11% adoption rate.
- In Europe, while exact percentages are not provided, the search results indicate that high-performance windows are commonplace in new and existing housing[1], implying much higher adoption rates compared to Australia.
So in summary, the percentage of houses with double glazing or high-performance windows is extremely low in Australia at around 10-11%, whereas in the UK, US, New Zealand and other parts of Europe, the adoption rates are around 80-90%[1][3][4]. This highlights the significant gap in the uptake of energy-efficient windows between Australia and other developed nations.
