Sustainability

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.

Windows are often one of the greatest contributors to energy loss in Australian homes. Choosing the right energy-efficient window solution can reduce heating and cooling demand, improve indoor comfort and help meet modern energy standards.

If you're renovating or building and want to improve your home's energy efficiency, Low-E glass is worth considering. Short for low-emissivity glass, this high-performance glazing helps regulate indoor temperatures, reduces energy bills and boosts comfort—all without sacrificing natural light.

Yes, but the benefits vary depending on location. In cooler parts of Australia (like Victoria, Tasmania or the ACT), double glazing significantly improves warmth retention. In hotter areas (like Queensland or northern NSW), it helps prevent heat gain, especially when combined with low-E glass or reflective coatings.

When it comes to designing a home that stays naturally warm in winter and cool in summer, thermal mass plays a big role. But what many homeowners don’t realise is just how much the effectiveness of thermal mass depends on the windows around it.
