The Window Energy Rating Scheme (WERS) provides a scientifically based, fair and credible rating system for the assessment of fenestration products for their energy efficiency performance. WERS is accredited by the Australian Fenestration Rating Council (AFRC) and adheres to AFRC protocols and procedures for the rating of Total System windows and glazed doors. Energy Ratings provided by WERS are third party certified to the AFRC requirements, compliant with the National Construction Code (NCC), and able to be used to meet regulatory requirements.

Projects designed under the Passive House (Passivhaus) methodology – using the Performance Solution pathway to the NCC – require glass-only performance data assessed to European Standards (EN). To support this, we provide performance data for all of our glass products in accordance with these standards.
