Window Ratings

Both Canterbury Timber Windows and Doors and Southern Star Aluminium Windows and Doors are a member of the Australian Window Association (AWA) and all timber and aluminium products are tested and rated under the Window Energy Rating Scheme (WERS). WERS is managed by the AWA and enables windows to be rated and labelled for their annual energy impact on a whole house, in any climate of Australia.

To participate in WERS, window makers must obtain energy ratings for their products from a rating organisation that is accredited by the AFRC (Australian Fenestration Rating Council) WERS is independent of any one manufacturer and acts as a fair, rigorous and credible system for testing performance claims. WERS-rated windows must meet all relevant Australian standards. The scheme forms part of the quality assurance that smart manufacturers offer their customers. It is all about certified performance.
