What are energy efficient windows?

Windows are one of the main reasons a home loses heat in winter and gains heat in summer. Selecting high performance windows is critical to achieving modern energy efficiency standards and reducing ongoing energy bills.

Climate considerations for windows

When selecting windows for a new build or renovation, it is essential to consider Australia’s varied climate zones and the latest energy efficiency requirements. The National Construction Code (NCC) now mandates a minimum 7‑star NatHERS rating for all new residential projects.

Window Energy Rating Scheme

The Window Energy Rating Scheme (WERS) enables windows and glazed doors to be rated and labelled according to their annual energy impact on a house in any Australian climate. WERS is managed by the Australian Glass and Window Association and complies with the protocols of the Australian Fenestration Rating Council.
