On hot days, up to 87% of heat gain in our homes is through windows. On cold days, it's 40% of heat loss. Here's how we can fix that

Thu, 2023-09-07 06:13
Compared to roughly 80% in the US, UK and NZ, only 11% of Australian homes have high-performance windows. Installing them can transform a household’s comfort, energy use and emissions.
