Window and Door for 7-Stars - Queensland

When it comes to evaluating the performance of your Windows and Doors, there are several factors to be considered when deciding the best options for keeping your home thermally comfortable. Glazing has the greatest impact and which glass is best depends on your climate and whether more energy is used heating or cooling your house: ‘Climate zones’ are defined by the Australian Building Codes Board, referenced in the National Construction Code and they are used in energy rating a home.

Achieving Energy Efficiency in Queensland

Climate Zones in Queensland

The Queensland coastal region (climate zone 2) is primarily a cooling climate, so it is most important that your Windows and Doors have a low Solar Heat Gain Coefficient (SHGC), as you want to prevent the heat from the sun from entering your house.

At the same time, climate zone 2 experiences mild winters, so having windows with a lower U Value is equally important. A lower U Value contributes to energy efficiency by minimising heat loss and reducing the need for heating in cooler seasons. In turn, this lowers energy consumption and associated heating costs.

For the Western region, including Toowoomba and Dalby (climate zone 5), please refer to the Window and Door Specification for 7-Stars - NSW guide.

Options for improving your Energy Efficiency through glass

To make your selection easier, we've created a good, better, and best glass offer for the Queensland climate zone, with tiered performance levels. While performance will be a major consideration in deciding which glass to use, other factors such as cost, window colour, availability, and lead times may also play a role. There are many other options available to meet a variety of needs; please contact your Trend representative for more information.
