How to Choose Quality Windows and Doors (and a Supplier You Can Trust)

Choosing new windows and doors is a bigger decision than most homeowners realise. It’s not just about the look, it’s about what they’re actually made from, how well they’re built, and who stands behind them once they’re installed. With recent industry testing and media reporting raising real questions about the quality of some imported aluminium windows, including issues with water sealing and structural performance under storm conditions, it’s never been more important to know what you’re buying and who you’re buying it from.

Here’s how to spot a genuinely good window or door, and how to choose a supplier you can trust to deliver one.

What Makes a Quality uPVC Window or Door

Not all uPVC is created equal. Here’s what actually separates a quality window from a budget one.

Check the profile system

Performance comes down to the quality of the profile the window is built on. Look for windows built on established, engineered systems, such as Aluplast, engineered in Germany, rather than generic or unbranded uPVC, which can vary widely in strength and insulation performance.

Check the glazing specification

A good uPVC window should be paired with proper double glazing, and ideally you’ll be able to see the U-value (the measure of heat transfer through the unit). Lower U-values mean better insulation and lower energy bills.

Check the hardware and seals

Hinges, locks and seals are where cheaper windows tend to cut corners first. Ask what hardware brand is used and how the seals are rated for weather resistance and security, since this determines how well the window performs over time, not just on day one.

Check UV stability and colour options

Good uPVC should be UV-stabilised so it won’t yellow or degrade under Melbourne’s summer sun. Vue’s range of colours and finishes are built on the same UV-stable profile, so appearance doesn’t come at the cost of durability. If a supplier can’t speak confidently to this, it’s a sign the profile may be lower grade.

The Quality Checklist

Use this as a quick reference when comparing options:

• Manufactured locally for Australian conditions
• Complies with AS2047 (windows) and AS1288 (glass)
• Clear WERS energy rating available on request
• Warranty covers frame, glazing, hardware and installation
• Steel-reinforced frame construction where needed for strength
• Weather-rated compression seals
• Secure multi-point locking system
• UV-stabilised profile with genuine colour options

Why This Matters Right Now

Recent independent testing commissioned as part of an ongoing investigation into imported aluminium windows has raised serious concerns across the industry, with reports of products failing to meet Australian Building Code requirements, struggling with water tightness, and in some cases risking structural failure in storm-force conditions.

This isn’t about scaremongering. It’s a reminder that not all windows are built to the same standard, and a window that looks fine in a showroom can perform very differently once it’s facing Melbourne’s wind, rain and temperature swings for the next twenty years. The supplier you choose, and where your windows are actually made, matters just as much as the material.

How to Choose the Right Window or Door Supplier: Things to Consider

Where are the windows actually made?

Ask directly. Locally manufactured windows are built and tested for Australian conditions from the ground up, rather than adapted from a design made for a different climate. This is exactly the gap that’s been showing up in recent testing of imported product.

Is the product compliant and certified?

Look for compliance with both AS2047 (the Australian Standard for windows and doors) and AS1288 (the companion standard covering glass thickness and safety), and check whether the supplier can show you a WERS rating. A reputable supplier won’t hesitate to walk you through this, and Vue holds its Aluplast uPVC windows and doors to both standards.

What does the warranty actually cover?

Not all warranties are equal. Ask how long it runs, and whether it covers the frame, the glazing, the hardware and the installation itself, or just some of these. A supplier confident in their product will offer a warranty that reflects that confidence.

What’s their reputation like?

Check reviews and past customer experiences, ask for references, and look at how long they’ve been operating locally. A supplier with a long track record in your area has a reputation to protect, which tends to show up in the quality of their work.

What does their installation process actually look like?

Even the best window can underperform if it’s installed poorly. A good installer measures precisely, protects your home during the work, and keeps you informed at every stage. If you’re weighing up a full window replacement, ask exactly how the process runs from measure to final fit, not just what the finished product looks like.

How do you read a quote properly?

A trustworthy quote breaks down exactly what you’re paying for: the frame material, the glazing type, the hardware, and the installation, each listed separately rather than bundled into one number. If a quote is vague about what’s included, ask for the breakdown before comparing it to anyone else’s. The cheapest quote isn’t automatically the best value, and the most expensive isn’t automatically the best quality; what matters is understanding exactly what sits behind the number.

Red Flags to Watch Out For

• A supplier who can’t clearly explain where the windows are manufactured
• No certification or compliance documentation available on request
• A warranty that’s vague about what it actually covers
• A quote that doesn’t break down materials, glazing and installation separately
• Pricing that seems significantly below every other quote you’ve received, without a clear explanation why

Quick Recap

• Check the profile, glazing spec, hardware and UV stability before anything else
• Confirm AS2047 and AS1288 compliance, plus a WERS rating
• Read the warranty in full, not just the headline length
• Ask how installation actually runs, from measure to final fit
• Get an itemised quote, not a single lump sum
• Locally made and independently reputable beats a cheap, vague promise every time
