How Much Do Double Glazed Windows Cost in Australia?

Double-glazed windows take priority among Australian house owners because they deliver energy performance and sound blocking alongside enhanced comfort. The expenses related to double-glazed windows vary in Australia's market. The complete expense breakdown regarding materials and installation for double-glazed window installation helps homeowners decide better when they choose between retrofitting an existing property or designing new construction.

This detailed cost guide will outline typical double glazing expenses and essential price factors, as well as evaluate different frame types and present installation cost estimates for various Australian states.

Average Cost of Double Glazed Windows in Australia

Price Range Per Window

• Standard double-glazed windows cost between $400 and $1,500 per unit when suppliers only provide them (without installation labour).



• The cost of windows extends from $600 for supply and labour up to $2,000 or more, depending on the installation requirements.

• Frame material (uPVC, aluminium, timber)



• The different window options include casement, sliding, awning and tilt and turn.



• Size and number of panels



• Glazing type (standard, low-E, argon-filled)

The total expense for double-glazed windows in Australian homes falls into the following cost ranges per window:

• An installed fixed window normally ranges in price from $600 to $1,200. Non-opening windows used to maximise both indoor illumination and exterior views cost $600 to $1,200 in supply-only form.



• An installed awning window usually costs between $800 to $1,500 based on current market rates. Hinged from the top, these windows open toward the outside for ventilation with light rain protection.



• The installation costs for sliding windows fall between $750 and $1,600. Because of their horizontal sliding mechanism, these windows serve as a common, lightweight and space-efficient choice.



• When installed, the price range for casement windows stands between $850 and $1,800. These windows swing from the side to reveal themselves as doors that allow great ventilation.



• The installation prices for tilt and turn windows start at $1,000 before reaching $2,000 with optional features and vary according to window size. These windows offer two functions since they both pivot inward on the top and also operate like doors for outside access.



• The installation expenses for bay windows extend from $2,500 to $5,000 and above. These window designs protrude beyond the house structure to generate interior room extension while enabling vast light admission.

Cost by Frame Type

UPVC (Unplasticised Polyvinyl Chloride)

• Cost: $600 – $1,200 per window (installed)



• These windows excel at insulation while needing minimal care due to their resistance against decay and rust factors.



• The choice does not align with buildings that require traditional historic construction.

Australian consumers often select uPVC frames as their preferred and affordable choice for double-glazed window applications. This product operates effectively throughout both hot and chilly weather conditions.

Aluminium

• Cost: $750 – $1,500 per window



• High strength and modern appeal, together with durability, make up its main advantages.



• The material allows heat to pass through easily because of which means energy efficiency needs thermal break systems.

Aluminium works well in coastal regions because it resists corrosion, yet its thermal efficiency needs thermal breaking to avoid decreased effectiveness.

Timber

• Cost: $900 – $2,000+ per window (installed)


• These windows boast visual attractiveness while being eco-friendly when sustainably harvested and showing insulation properties.


• The material needs extra upkeep because humidity causes it to warp.

The interior of homes constructed with timber frames appears best suited for historical properties that also seek a classic rustic design. Prices run higher on these windows due to material costs, together with maintenance expenses.

Glazing Options and Their Impact on Cost

• The standard option uses two glass panes with air trapped between them. This constitutes the minimum requirement for most installations.



• Low-E glass enables heat reflection inside rooms and light entry through windows, with an additional expense of between $50 to $100 per unit.



• Windows that contain argon gas insulation cost between $50–$80 more than units that use air instead.



• The installation of triple-glazed windows, including three glass panes, represents a very uncommon glazing option in Australia and adds 30-50% to the price of double glazing.

Retrofitting vs. New Installations

Cost: $800 – $1,800 per window

Double glazing retrofits existing frames when the frames are in good condition, especially for timber or aluminium constructions.

Specialised companies in Australia focus on installing double glass panes through secondary glazing systems for single-pane windows. Installing double-glazing on the exterior of windows proves both affordable and suitable as an alternative method.

Cost: $600 – $1,500 per window

It becomes cheaper and easier to install double-glazed units at new construction time because workers need less labour, and frames can accommodate specific glazing requirements.

Labour and Installation Costs

The labour cost for window installation normally falls within the range of $150 to $300 for each window, yet some variations are based on the following factors:

• Accessibility (ground floor vs. upper floors)



• Complexity (bay windows, tilt and turn, custom shapes)



• The glazing expenses in regions mostly depend on whether you live within a municipal area or a state location. Metro areas usually charge higher costs than others.

The installation expenses are higher in Sydney, Melbourne and Brisbane than in regional locations, although trades tend to be more expensive in metropolitan areas while remaining less accessible across the region.

State-by-State Pricing Guide

The installation prices for standard double-glazed casement windows range from $1,000 to $1,800, including labour across New South Wales (Sydney). Here are the average cost range for all states:

• New South Wales (Sydney): $1,000 – $1,800



• Victoria (Melbourne): $950 – $1,700



• Queensland (Brisbane): $900 – $1,600



• Western Australia (Perth): $850 – $1,500



• South Australia (Adelaide): $800 – $1,400



• Tasmania: $900 – $1,600



• ACT (Canberra): $950 – $1,700

Full Home Double Glazing Cost Estimates

Thinking of double glazing your entire home? Property size determines the cost estimates with the following general values:

• 1-bedroom unit (5–7 windows): $5,000 – $12,000



• 3-bedroom house (10–15 windows): $10,000 – $25,000



• 4-bedroom house (15–20+ windows): $20,000 – $40,000+

The total unit cost might decrease through bulk purchases and a single job window project.

Final Thoughts: Is It Worth the Investment?

Later life benefits from double-glazing windows start with initial high costs because they help reduce utility expenses and bring lower heating and cooling bills, and lead to higher property market value. Constructing new homes requires double-glazed windows, probably because the advantages are obvious in this situation. The return on investment for double-glazing homes located in cold or noisy locations will show benefits in the long term.

You should obtain multiple quotes and assess materials and styles before purchasing double-glazed windows to ensure financial assistance from available rebates or schemes. The proper planning methods enable double glazing to serve as a smart home upgrade with sustainable benefits for Australian residential properties.
