How do windows and doors achieve NCC 2022's 7-star NatHERS rating?

NCC 2022 mandates a 7-star NatHERS rating for new homes, requiring high-performance glazing and thermally broken frames to manage heat transfer. While double glazing isn't always mandatory, optimising window properties like U-value and SHGC, alongside design choices such as orientation and size, is crucial. This approach helps reduce energy bills and improve comfort across Australia's diverse climate zones.
