and as you will see - I back what I say with references ----------------- all we get from you is arse birthed opinions of no value in advancing debates forward

did you know that Oz is a hot country?

did you know that about 80% of heat entering a house, comes in via the windows?

and yet the uptake of high performance windows in Australia is dismal -

cheap shitty windows provided by builders who charge top dollar ----------- you don't need to be an expert to see a scam ---------- you do have to have some observation skills and a few functioning neurones - connected

In Australian homes, up to 87% of heat gain in summer is through the windows[1][4]. Single-glazed windows are common in Australian housing, and heat travels easily through these windows, making them a thermal weak spot[1][4].
On hot days, most of the heat that gets into Australian homes is through the windows[4]. This makes it harder to maintain a comfortable temperature inside and increases the need for energy-intensive cooling systems like air conditioning[1][4].
## Improving Window Performance
Double-glazed and triple-glazed windows offer much better thermal performance, reducing the need for heating and cooling[1][4]. These windows have insulating layers of air or gas between the glass panes, which act as a barrier to heat transfer[1][2].
Other elements like low-emissivity coatings, thermal breaks in the frames, and window films can further improve the thermal performance of windows[1][4].
Retrofitting existing single-glazed windows with secondary glazing, which involves installing an additional glazed panel inside the existing window frame, is a cost-effective option to improve thermal performance without full window replacement[1][4].
High-performance windows not only enhance thermal comfort but also offer benefits like better natural light control, reduced outdoor noise, and improved physical and mental health by maintaining comfortable indoor temperatures[1][4].

shut up , dribbler, you know nothing about building for a start builders dont make the windows, they install what the client wants and can afford, get your hand off it
