High-performing windows and doors can make heating or cooling your home simpler and more cost effective, saving money on expensive electricity and gas. Although they are much larger framing systems, Elevate™ window and door systems are WERS-rated and tested to make choosing the right product as simple as possible to deliver comfort and performance in any environment.
To get the highest energy efficiency from your windows and doors, it’s important that they are installed by a qualified professional, and located in the best position to take advantage of natural cross ventilation, light and solar heat gain in both summer and winter.
U-values are the measure of how much heat is transferred through a window or door. The lower the U-value the more efficient it is at keeping the heat or cold out.
SHGC measures how much solar radiation passes through a window or door. In a cool climate, a high SHCG will allow more solar heat to enter your home.
WERS is the Window Energy Rating Scheme for windows and doors in Australia. It uses a 10-star system to rate the annual energy impact on a home, based on its U-value and Solar Heat Gain Coefficient (SHGC). The more stars, the better.

When EJE Architecture put forward an inspired façade for the GWH Darby Plaza project, Hunter Windows was tasked with making it a reality.
When EJE Architecture put forward an inspired façade design for the GWH Darby Plaza project, Hunter Windows was tasked with bringing it to life.
The challenge involved merging traditional strip windows with a glass curtain wall system—two typically incompatible systems—while following the building’s curved exterior form.
To achieve the desired seamless aesthetic, Hunter Windows developed a custom cast-in bracket system supporting glazed spandrels that appeared as continuous glass from the outside while functioning as balustrades inside. The result met all thermal, acoustic, and fire-rating requirements while maintaining the clean, contemporary look of a curtain wall.
The combination of the precast panelling, large glazed areas, and unique aluminium decorative panels gives Darby Plaza its standout architectural character—a striking addition to Newcastle’s evolving skyline.
