What’s wrong with Australian windows?

“We’re dumping energy to maintain comfort.” 

That’s how Andre Griffs from BINQ sums up what’s happening in far too many Australian homes. We crank the heater, blast the air con, and wonder why the house still feels off. Often, the culprit is simple. The windows are not performing.

We sat down with Andre to unpack what’s going wrong with Australian windows, why it matters more than most people realise, and what BINQ is doing differently to lift the standard.

The Problem with Australian Windows 

Andre didn’t mince words. Most windows in Australian homes aren’t doing anywhere near enough to handle real-world conditions, especially in places like Victoria, where temperatures can swing from minus 2 to 40 degrees. That kind of range isn’t mild climate territory. It’s a stress test.

And yet, the story we keep telling ourselves is that Australia doesn’t need high-performance windows. Andre’s take is simple. This belief has become an excuse. Weak regulations and buyer habits have kept the market stuck, and the result is homes that waste energy are generally inefficient and never quite feel comfortable.

What BINQ Is Doing Differently

BINQ’s approach starts with a basic premise: design for performance from day one. Andre explained that a lot of window systems in Australia were originally designed for single glazing, then awkwardly upgraded later. BINQ doesn’t do that. Their windows are built to accommodate double glazing from the start, which makes the jump to better performance far more straightforward.

We also got into materials, specifically uPVC (unplasticised polyvinyl chloride). Andre’s argument is practical. uPVC delivers strong insulating performance and long lifespan, with lower embodied carbon than many traditional aluminium options. Aluminium gets points for recyclability, sure, but Andre’s view is that recyclability doesn’t automatically equal high performance, especially when thermal efficiency is the priority.

The Real Barrier: Adoption (and Messaging)

The benefits are obvious once you understand them. Better comfort, lower energy bills, and less reliance on mechanical heating and cooling. But adoption is still slow.

Andre thinks part of the problem is cultural inertia, and part of it is messaging. People don’t buy windows because they’re excited about window specs. They buy them because they want a home that feels good to live in. BINQ is trying to shift the conversation by educating clients properly. Less “trust us”, more “here’s what this means for your house.”

What’s Next: Composite Windows

Andre also shared what’s coming next for BINQ. Composite windows are designed to bring together the warmth of timber aesthetics with the durability of aluminium cladding. The goal is simple. Make high-performance windows easier to say yes to, without forcing people to choose between looks and function.

Windows aren’t a finishing touch. They’re a performance decision.

And if Australia wants healthier, more comfortable, more energy-efficient homes, we can’t keep treating windows like a commodity. Conversations like this, with people like Andre pushing the industry forward, are how standards lift.

If you’re building or renovating and you’ve never thought deeply about your windows, we hope this article and episode help you to think differently and do more research in the future.
