Because we are serious about energy efficiency, our supplier is one of the few manufacturers who have obtained WERS testing on all of their products.
The Window Energy Rating Scheme (WERS) is an organization that enables windows and glazing products to be rated and compared based on their ‘whole of window’ performance.
This means WERS tests not just the glass, but the window frame as well (super important!)
For a manufacturer to participate and be rated in WERS, they must submit their products to an independent testing authority accredited by the Australian Fenestration Rating Council.
Very few, if any, of our competitors have accredited their product through the Window Energy Rating Scheme (WERS), which is a subset of the Australian Window Associated. To quote the website:
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.
In other words, if the product is not accredited through WERS, there is no guarantee of the thermal performance of the glazing based on Australian standards.
Many of our competitors will quote thermal conductivity values (U-values) that are not based on Australian performance standards and are instead based on European performance standards. The European values generally sound more impressive (such as U-values of less than 1), but these performance values are simply not achievable when measured against Australian performance measures (a U-value less than 1 is not realistic).
Our products (manufactured by Australian Glass and Glazing) are listed here and the performance values are verifiable through WERS.
