In sustainable building, insulation often gets the spotlight. It’s what keeps homes warm in winter, cool in summer, and reduces energy bills. But without airtightness, insulation can be wasted. Gaps and leaks in the building fabric allow warm air (and…
When specifiers look at insulation options, PIR often gets the nod for its low thermal conductivity and slim build-ups. But performance on paper rarely tells the full story. At Back to Earth, we find it far more useful to evaluate…
When retrofitting solid wall buildings, especially those using external wood fibre insulation, choosing the right render is crucial. While traditional lime renders still have their place, they’re not always suited to modern performance demands. Silicone render offers a practical blend…

Can You Partially Insulate a Building? Risks, Strategies, and Best Practice It’s a question that comes up regularly: can you insulate a building in stages, rather than all at once?In short—yes, you can. But the real answer is more nuanced,…
Airtightness, Breathability, and Vapour Control: How to Make It All Work Together When it comes to building performance, few topics generate as much confusion—and controversy – as airtightness, breathability, and vapour control. Can you really make a building airtight an…
Why Do We Insulate Buildings? It might seem like a basic question, but it’s one that’s worth revisiting. Why do we insulate our homes and buildings? While many clients come to us already committed to insulation, the full scope of…
Solid Wall Insulation – Is External or Internal Insulation Better? When it comes to upgrading the insulation of solid-walled homes, one of the biggest decisions is whether to insulate from the outside or the inside. Both external wall insulation (EWI)…
