When renovating or building a home, windows often account for a significant portion of your overall budget. The standard cost of a window depends on a variety of factors, including type, size, material, glazing, and installation. 

Understanding these key elements will help homeowners make informed decisions when budgeting for new windows. This article breaks down the standard cost of a window in Australia, providing a clear guide to help you navigate the complexities of window prices.

1. Window Type And Its Impact On Cost

The type of window you choose can have a major impact on the overall cost. Windows comes in a wide range of styles, each offering different functions, features, and price points. Below are the most common window types and their associated costs.

• Fixed Windows: These are non-opening windows, offering a simple, low-cost solution. Fixed windows are typically the most affordable, with prices ranging from $150 to $400 depending on size and material.
• Sliding Windows: Sliding windows are popular in Australian homes for their ease of use and functionality. They are usually priced between $200 and $600 per unit.
• Awning Windows: These windows open outward from the bottom, offering weather protection and ventilation. Awning windows usually cost between $300 and $700 each.
• Double-Hung Windows: Known for their versatility, double-hung windows open from both the top and bottom. They typically cost between $400 and $800 per unit.
• Casement Windows: Hinged at the side, casement windows open outward like a door. These elegant windows generally cost between $400 and $900.
• Bay or Bow Windows: These larger, more complex windows create extra space and add a distinctive design element to a home. Bay or bow windows typically cost $1,500 to $3,000 or more per window, depending on size and customisation.

2. Material Of The Window Frame

The material of the window frame plays a crucial role in determining both the cost and the overall appearance of the window. Different frame materials come with varying price tags based on durability, aesthetics, and insulation properties.

• Aluminium Frames: Aluminium is a cost-effective and durable choice for window frames. The price range for aluminium frames is typically between $150 and $1,000, depending on the type and size of the window.
• Timber Frames: Timber is often chosen for its natural aesthetic appeal and excellent insulation properties. However, timber frames are generally more expensive, with prices ranging from $300 to $2,000 per window.
• uPVC Frames: Unplasticised polyvinyl chloride (uPVC) is a low-maintenance material known for its energy efficiency. The price of uPVC frames typically ranges from $250 to $1,500, depending on the size and design.
• Composite Frames: Composite frames are made from a blend of timber and aluminium, offering the benefits of both materials. These frames can cost between $400 and $2,500, depending on the complexity and size of the window.

3. Glazing Options And Their Effect On Price

The type of glazing you select for your windows can significantly influence the overall cost. With rising demand for energy-efficient solutions, glazing options like double and triple glazing are increasingly popular. Below are the common glazing options and their associated costs:

• Single Glazing: This is the most basic type of glazing, offering minimal insulation. Single-glazed windows typically cost $50 per square metre and are the least expensive option available.
• Double Glazing: Double-glazed windows are a popular choice for homes, offering improved insulation and noise reduction. The cost for double glazing generally ranges from $150 to $300 per square metre.
• Triple Glazing: Offering superior insulation and noise reduction, triple glazing is the most expensive option. Triple-glazed windows typically cost $250 to $400 per square metre.
• Low-E Glass: Low-emissivity (Low-E) glass is coated with a special layer that reflects heat, helping to improve energy efficiency. The cost of Low-E glass typically adds $50 to $150 per square metre to the price of the window.
• Tinted or Frosted Glass: Tinted or frosted glass is often used for privacy or to reduce UV rays. This option generally adds $30 to $100 per square metre to the price of the window.

4. Size And Customisation

Window size plays a significant role in the overall cost. Standard-sized windows are usually more affordable than custom-made windows, which require specialised manufacturing. Here’s a breakdown of how size and customisation affect pricing:

• Standard Size Windows: Small, standard-sized windows typically cost around $150 to $400. These windows are the easiest and most affordable to install.
• Large or Custom Windows: Larger windows, or those with custom shapes (such as bay windows), can significantly increase the cost. Prices for custom windows generally start at $1,000 and can go up to $3,000 or more, depending on the design and size.
• Oversized or Floor-to-Ceiling Windows: These large, high-end windows can exceed $2,000 per unit. These are typically used for grand architectural features or as part of a modern design.

5. Installation Costs

The installation of windows is another factor that contributes to the overall cost. The complexity of the installation, the number of windows, and any special requirements will influence how much you pay for fitting. On average, installation costs range as follows:

• Standard Installations: For typical window installations, homeowners can expect to pay between $150 and $400 per window for labour.
• Complex Installations: More complex installations, such as large or awkwardly positioned windows, may increase costs. These can range between $500 and $1,000 per window.
• Additional Costs: If old windows need to be removed or structural modifications are required, these tasks will add extra costs to your window installation. Expect to pay an additional $50 to $200 for window removal and disposal.

6. Brand And Supplier Variations

The brand and supplier you choose can also impact the cost of your windows. High-end brands may charge more for their products, but these often come with guarantees of quality, performance, and durability. 

Local suppliers may offer competitive pricing, though imported windows could incur higher costs due to shipping and import duties. Here’s a summary of how brand and supplier affect cost:

• Reputable Brands: Premium brands typically cost more due to their proven quality, long warranties, and reliable performance.
• Local Suppliers: Local suppliers may offer more affordable prices, though the range of options may be limited.
• Imported Windows: Windows sourced from international suppliers could be more expensive due to shipping costs, import duties, and other fees.

Tips For Reducing Window Costs

If you want to reduce the overall cost of your windows without compromising on quality, consider the following tips:

1. Get Multiple Quotes: Always compare quotes from different suppliers and installers. This helps you find the best deal and ensures competitive pricing.
2. Choose Standard Sizes: Standard-sized windows are usually cheaper than custom-made windows. Opt for these whenever possible to save money.
3. Consider Energy Efficiency: Although energy-efficient options like double or triple glazing may cost more upfront, they can lower energy bills in the long term. Look for windows that offer good insulation and heat retention.
4. Bulk Purchases: If you’re replacing multiple windows, consider purchasing in bulk. Many suppliers offer discounts for larger orders.
5. DIY Installation: If you’re skilled in DIY, installing the windows yourself can save on labour costs. Ensure that you follow all safety regulations and building codes.
6. Wait for Sales: Look out for promotional periods or off-season discounts. Many suppliers offer lower prices during these times, especially if you’re not in a rush to complete the installation.

Hidden Costs To Consider

• Old Window Removal: Removal and disposal of old windows can add between $50 and $200 per window.
• Structural Modifications: If you need to reinforce walls or resize window openings, these costs can significantly increase the overall price of the installation.
• Permits and Approvals: Depending on your local council, you may need a permit for window installation. Permits can cost anywhere from $100 to $500, depending on your area.
• Delivery Fees: Large or heavy windows may incur additional delivery fees, ranging from $50 to $300.

Conclusion

Understanding the factors that influence the cost of windows in Australia can help homeowners make informed choices that suit both their budget and design preferences. From the type of window and frame material to glazing options and installation, each decision can impact the final price. 

To reduce costs, consider standard sizes, and energy-efficient choices, and seek multiple quotes. If you’re looking to improve your home’s energy efficiency without replacing all your windows, retrofit double glazing is an excellent option to enhance insulation and comfort without breaking the bank.
