Window Energy Rating Scheme - WERS


With up to 40% of a home’s energy for cooling or heating being lost or gained through windows, their performance is vital in reducing energy costs and greenhouse gas emissions.

We can measure the effectiveness of individual windows by using the Window Energy Ratings Scheme (WERS). WERS was specifically developed to rate and categorise the energy impact of windows in Australia.

WERS rates windows based on several factors including heating efficiency, cooling efficiency, U-value, solar heat, visible light transmittance and air infiltration.

The program is accredited by the Australian Fenestration Rating Council (AFRC) and adheres to AFRC protocols and procedures for the rating of windows and glazed doors.

You can rest assured that WERS ratings are third party certified, compliant with the National Construction Code (NCC), and able to be used to meet regulatory requirements.

All window products manufactured by the Southern Star Group are WERS rated and our alliance with industry groups like the Australian Window Association ensures our products comply with standards and codes.

We have a stellar range available including high performance windows that affect the comfort and resale value of your home, increasing energy efficiency, noise reduction and security.
