The R value of wood is not great [1] and would depend on the type of wood used and thickness. Double pane windows tend to have an R value of 1-2, which increases if filled with a gas [2]. Your hypothesis that we'd curb more energy loss is a bit misplaced without more nuance.

- Qwertious 6y agoDouble glazed windows might be more efficient, but that's irrelevant if you simply don't use double-glazed windows. I know single-glazed is quite common in Australia, apparently because there's no local factory for mass producing double-glazed and there's no market base right now because it's so expensive because it's imported, so nobody wants to take the risk.
- kube-system 6y agoProbably less risky to open up a double-glazed window factory than it is to open up a transparent wood window factory.
- spockz 6y agoDouble glazed has been standard for at least 20 years if not 30 here in the Netherlands. It is primarily intended to keep warmth inside during colder periods. Newer projects tend to have triple or quadruple glazed glass with all kind of coatings. To keep the heat out in summer an infrared blocking coating is applied. In office buildings here it is more efficiënt to heat a bit more in winter due to loss of IR than to cool extra in summer.
- nightcracker 6y agoHere in the Netherlands most everything newly built is built with double glass.
- cfn 6y agoThat is surprising given the amount of AC you use. I lived for a few years in a similar climate to Melbourne and double glazing made a huge difference in the Summer.
- hutzlibu 6y ago"so nobody wants to take the risk" And everyone just uses more AC. Which surely is not more expensive. Oh and right, thats the reason Australia absolutely needs coal to burn.
- doctor_eval 6y agoI’m not sure that’s true. We had gas filled double glazed windows made for us in Eltham, an outer suburb of Melbourne, during a renovation about 6 years ago. We replaced all the single paned glass with double panes. And we were on the edge of the Yarra valley, not particularly close to the city. So my experience doesn’t match this at all.
- Mandatum 6y agoIt's because it isn't true. There's a number of outfits and pretty much every new apartment building has double glazing. I've lived in 4 properties since moving to this country, 2 with and 2 without. Of those with, 1 new and 1 probably last renovated 15 years ago.
