"SIPS will never work in Australia" - that's what many builders said about Structural Insulated Panels just a few years ago. Today, we're exploring why companies like Fenster & Panel are proving them wrong.

We sit down with Dave to understand why SIPS are gaining traction in Australian construction. These engineered panels combine structural strength and insulation, offering faster construction times, reduced waste, and better thermal efficiency. For an industry facing skilled labour shortages and rising energy costs, these benefits are becoming increasingly attractive. Dave shares practical insights about shifting from traditional methods to prefabricated solutions, addressing common concerns while demonstrating real-world value.

"We love the design, but can you make it cheaper?"

Every builder has heard this request, and it highlights one of the biggest challenges facing our industry today. The gap between what clients want and what they can afford is widening, leaving architects, builders, and clients frustrated. We need to talk about why this is happening and what we can actually do about it.

The solution requires cooperation between clients, architects, and builders from day one. Everyone needs to understand pricing complexities, and we need to work towards realistic briefs that align with financial realities without compromising quality or sustainability.

This means involving builders in early design conversations, establishing clear budget parameters upfront, and maintaining open communication throughout the process. When all parties understand the constraints and possibilities, better outcomes become achievable.

The industry is evolving, and those who embrace collaborative approaches will be best positioned for success.

In this episode, we sit down with Harley Truong, the godfather of Passive Houses in Australia, to explore his incredible journey from public servant to sustainability pioneer. Twelve years ago, Harley was working at the Department of Defence in Canberra when he decided he'd had enough of Australia's zero-star energy efficiency housing and drafty homes. We dive into how he took on the ambitious challenge of building his own passive house without ever having stepped foot in one, using research from Germany's Passive House Institute to create what would become a trendsetting masterpiece.

We talk about the reality of building without a blueprint and how Harley had to literally rewrite the rules to achieve his vision. His meticulous approach resulted in an astounding 0.1 air changes per hour—and we explore what that actually means and why it matters. The conversation gets really interesting when we discuss how one exceptional house wasn't enough for Harley, leading him to recognise a massive gap in the Australian market and found Logikhaus to import high-performance European windows, essentially becoming both consultant and supplier to help other builders achieve their eco-dreams.

Throughout our chat, we explore Harley's bigger vision for the industry and how he's catalysing crucial conversations about providing better, more sustainable housing for all Australians. We discuss his goal of making high-performance windows the norm rather than the exception, and why he believes we're just at the beginning of an inclusive industry revolution. If you're interested in sustainable building, pioneering business moves, or just love hearing about someone who dared to dream bigger, this conversation will inspire you.

"What happens if I make my house airtight but have no mechanical ventilation?" This question comes up more often than you'd think, and the answer might surprise you. We sat down with Cameron Munro from Passive Analytics and Brad McEwan from Sanford BuildCo to tackle this and other building questions from our social media following that every builder should understand.

Building a high-performance home isn't just about achieving airtightness - it's about understanding how all building elements work together. The key takeaway? You cannot have an airtight building without proper mechanical ventilation. The energy and comfort benefits only work when you maintain healthy indoor air quality.

For builders serious about high-performance construction, remember that details matter, and investing in proper ventilation systems isn't optional - it's essential for creating truly healthy homes.

Winter hits different when you're working outdoors. The sun disappears by 4 pm, the cold seeps into your bones, and suddenly that motivation you had in summer feels like a distant memory. If you've noticed your mood dropping with the temperature, you're not imagining things. We sat down with our good friend and psychologist, Julie to understand why winter affects us so deeply and what we can actually do about it.

Winter challenges are normal, but they don't have to derail your mental health. These strategies work best when implemented consistently, not just when you're already struggling. If you notice symptoms persisting or worsening, professional help can make a significant difference.

Remember, acknowledging winter's impact on your mental state isn't weakness, it's awareness that leads to better self-care.

Window installation may not instantly grab your attention, but for anyone involved in building or renovating, it's a critical aspect that cannot be neglected. Think about why we have windows: they connect our living spaces with the outside world, offering natural light, beautiful views, and essential ventilation. However, beyond these obvious reasons, there is a layer of complexity and science in window installation that is necessary to explore further.

When it comes to window installation, the type of window is fundamentally essential. Each type has its nuances. It’s these differences that require us to break down and approach each installation uniquely. Matt aptly noted during our latest podcast that while there are some industry standards, every project has nuance and a unique set of challenges.

If you’re navigating window installations—whether you're a seasoned builder or an enthusiastic DIYer, it’s about more than just inserting glass into a gap. It's about strategising each move, considering the materials, and above all, applying a thoughtful blend of science and practicality to the process.

This is part 2 of our conversation with Cameron Munro about insulation. We recommend listening to part 1 first before listening to this episode.

—

When it comes to building or renovating a home, insulation is one of those topics that seems simple on the surface, but quickly gets complicated. That’s why we brought in Cameron Munro from Passive Analytics to help us break down how insulation really works. In part two of this conversation we pivot the topic to focus on insulation used in walls and roof spaces.

After talking with Cam, we’re more convinced than ever that insulation is about more than just picking a product off the shelf. It’s about understanding how heat and moisture move through your home, choosing the right materials for your climate and design, and making sure everything is installed with care. If you want a healthy, comfortable, and energy-efficient home, don’t cut corners on insulation—or on the expertise you bring in to get it right.

In our latest episode, we had the pleasure of sitting down with Dr. Cameron Munro from Passive Analytics to really dig into the world of insulation. If you’ve ever wondered why your house feels too hot or too cold, or if you’re curious about how the colour of your roof actually affects your comfort, this one’s for you.

Key Takeaways

• Insulation is about controlling heat transfer—conduction, convection, and radiation all matter.
• The colour of your roof or cladding has an impact, but it’s less important in well-designed, high-performance buildings.
• Still air is a great insulator; moving air (convection) is not.
• Windows are complex—double/triple glazing, air gaps, and coatings all affect performance.
• Context is everything: what works in one climate or building type may not work in another.
• Moisture management is just as important as thermal performance.

A huge thanks to Dr. Cameron Munro for sharing his expertise and helping us unpack the science (and myths) around insulation. If you’re designing, building, or renovating, we hope this episode—and this article—gives you a clearer understanding of what really matters when it comes to keeping your home comfortable and efficient.

We recorded this episode in two parts, so look out for part two where we move further into wall and roof insulation.
