WERS Ratings
Choosing the right windows and doors can make a high difference to your home’s
energy efficiency and comfort.
Our CityView range of windows and doors are WERs-rated and tested, making
it easy for builders and home owners to choose the right product to suit their home.
The Window Energy Rating Scheme (WERS) is accredited by the Australian Fenestration Rating Council.
It is a 10-star system used to rate the annual energy of windows and doors based on its u-value and SHGC.
The higher the star rating for a system, the more energy efficient it is. Please refer to the table below to see the WERs ratings for the CityView range of window and door systems.
U-Value (Uw) measures how readily a window system conducts heat.
It is a measure of the rate of non-solar heat loss or gain through it.
The rate of heat is indicated in the terms of the U-value of a window assembly
which includes the effect of the frame, glass, seals and spacers.
The lower the U-value, the greater the window’s resistance to heat flow and the
better its insultaing value.
Next to the text for Solar Hear Gain Co-efficient (SHGC) could you please add the attached image?
The Solar Heat Gain Co-efficient (SHGC) measures how effectively a window or door system blocks heat caused by sunlight.
The lower a window’s SHGC, the less solar heat it transmits.
