Residential Energy Ratings

Commercial Energy Ratings

They are specific ratings of glass and frame combinations that have been independently simulated and then passed through an audit process by WERS for independent companies.


The Window Energy Rating Scheme rates the whole of window or door energy efficiency performance.

WERS enables windows and doors to be rated and labelled for their annual energy impact on a whole house, in any climate of Australia.

To participate in WERS, energy ratings must be obtained by manufacturers for their products from a rating organisation that is accredited by the Australian Fenestration Ratings Council (AFRC).


Rated windows and doors display the WERS logo.

Each rated product has a certificate which certifies that it has been energy rated.

As compliance for energy rated products increases it becomes especially important you are able to ensure that you are purchasing compliant products.

WERS has produced a fact sheet to ensure that your window products are AFRC compliant.

To download the fact sheet, click here. This Fact Sheet includes a simple check list to determine if your products are compliant.
