The Southern Star Group is a member of various industry groups including:

  • Australian Window Association
  • Housing Industry Association

Energy Efficiency and WERS

The Window Energy Ratings Scheme (WERS) rates the energy impact of windows in housing anywhere in Australia. With up to 40% of a home’s energy for cooling or heating being lost or gained through windows, improving their thermal performance reduces energy costs and Australia’s greenhouse gas emissions.

WERS is a proprietary scheme whose members agree to a formal code of conduct and participate in an annual audit.

WERS results can only be claimed and used by WERS members.

All window and door products manufactured by the Southern Star Group are WERS rated and our alliance with all of these groups ensures that our products comply with their standards and codes and meet best practice.
