What affects the cost

Size of the window: Larger windows require more materials and labour, increasing the cost.
Frame material: Aluminium frames are generally cheaper than timber or uPVC, which offer better insulation but at a higher price.
Glass type: Specialised glass such as low-E or laminated glass can add to the cost due to their superior insulation properties.
Installation complexity: More complex installations, such as those requiring structural modifications, will incur higher labour costs.
Brand and quality: Premium brands with higher energy ratings often come at a premium price.
Additional features: Features like tinting, noise reduction, or security enhancements can further increase costs.

Regional variation across Australia

The cost of double glazed windows can vary depending on your location in Australia. In metropolitan areas like Sydney and Melbourne, prices tend to be higher due to increased labour and material costs. For instance, you might pay 10-15% more compared to regions like Adelaide or Perth. In Brisbane, costs are generally moderate but can rise in more affluent suburbs. Regional areas may offer lower prices but could involve higher transportation costs for materials.

Hidden or extra costs to budget for

Transport costs: If the supplier is far from your location, expect additional charges for delivery.
Old window removal: Removing and disposing of old windows can add to the overall cost.
Custom designs: Customised window shapes or sizes usually incur additional fees.
Permit fees: Some installations may require council approval, which can add to your budget.
Maintenance costs: Although minimal, periodic maintenance to keep frames and seals in good condition may be necessary.
