The Truth About Cheap Aussie Windows - Mindful Builder | Lyssna här

If you’ve ever wondered why Australian homes feel freezing in winter and brutal in summer, this episode makes it painfully clear. “Suppliers in Australia are still delivering single-glazed aluminium windows,” and that one sentence explains a lot about comfort, energy bills, condensation, and why so many people feel worn down inside their own homes.

We sit down with Monika Rogers from Eco Sky Windows to talk high performance windows, Passive House certified systems, and what “thermally broken” actually means. We discuss U-values, why the whole window unit matters (not just the glass), and how slimline design, hardware, and airtightness change real-world performance.

The conversation also goes beyond windows into indoor air quality and ventilation. Monika shares why she rates HRVs so highly, and the hosts describe what it felt like having 30 to 40 people in a sealed space that still felt fresh, clear, and comfortable. If you care about building better homes, this is a practical look at the details that actually move the needle.

We finish up with the realities builders and clients need to plan for: shop drawings, lead times, shipping, and cashflow. If you’ve been nervous about imported high performance windows, this episode breaks down the process and shows why organisation matters more than geography.
