To achieve the best performance, it’s important to consider not only the type of windows and doors you select but also their placement within your home’s design.
Window replacement
Thoughtful placement of windows and doors allows you to take advantage of passive design principles, delivering excellent thermal outcomes. Orientation, insulation, shading, and product selection all play a role in optimising energy efficiency.

Window energy rating scheme (WERS)
Bayview Glass aluminium window and door systems are tested under the Window Energy Rating Scheme (WERS), which measures the energy impact of windows in homes across Australia.
Since up to 40% of a home’s heating and cooling can be lost or gained through windows, WERS provides a clear way to compare products. Windows and doors are rated on a 10-star scale:
- Low star rating = poor energy efficiency
- High star rating = strong energy efficiency
- 10 stars = the theoretical perfect system
In practice, the highest-performing windows in Australia typically achieve 6–7 stars for heating and 4–5 stars for cooling.
Our ThermalHEART™ aluminium windows and many of our high-performance standard systems fall within this range.
