    How to obtain WERS ratings for windows and doors

    Infolink

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

    The AFRC's main function is to provide independent verification of product performance. The AFRC develop, administer and approve the only uniform, independent, comparative rating and labeling system for the energy performance of windows, doors, skylights and attachment products.

    The AFRC's data process and auditing flowchart demonstrates the lengthy process that's involved in obtaining energy ratings for windows, doors, skylights and attachment products.

    The AFRC's main goal is to provide fair, accurate, and reliable energy performance ratings so that:
    • Architects, builders, code officials, contractors, homeowners, and others can compare different products and make informed product choices. 
    • Building officials, state government employees, and others in code development and enforcement can determine if products meet local codes. 
    • Government and utility-run energy efficiency programs can establish performance requirements and standards. 
    • Manufacturers have a fair and level playing field to compare products and an accurate method of showing the energy benefits of new designs or technology.
    The Window Energy Rating Scheme (WERS) enables windows to be rated and labelled for their annual energy impact on a whole house, in any climate of Australia. WERS has compiled a list of factors that help determine which window and glass type is right for cold, mixed or hot climate zones.

    Window types:
    • aluminium
    • aluminium thermally broken
    • timber
    • uPVC
    • fibreglass
    • composite
    Glass types:
    • Clear Low E
    • Clear IGU
    • Clear IGU Low E
    • Tint
    • Tint, Clear Low E
    • Tint, Clear IGU
    • Tint, Clear IGU Low E
    • High performance tint
    • Tinted Low E (low gain)
    • Tint IGU
    • Tint IGU Low E (low gain)
