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.
