WERS Window Energy Rating Scheme


Click here for WERS energy ratings for Lidco Systems in pdf format.

The energy efficiency provisions of the Building Code of Australia (BCA) states that external glazing performance must be determined in accordance with the guidelines of the Australia Fenestration Rating Council (AFRC).

The Window Energy Rating Scheme (WERS) for windows in Australia is an independent scheme, owned and managed by the Australian Window Association.  WERS follows all AFRC protocols and processes as required by the BCA and is an accredited AFRC member. Lidco’s windows and door systems have been WERS rated, enabling specifiers to easily evaluate the relative energy performance of its different types of windows and doors and then make an informed decision suited to their requirements.

The window’s cooling and heating performance is rated separately on a scale of 0-10 stars: the more stars the better. These ratings indicate the effect the window will have on the energy performance of the whole house. The rating of a window is based on its U-Value and Solar Heat Gain Coefficient (SHGC) for the whole window, including glass, frame and seals.
