Why are so many houses in Cyprus damp – and hardly anyone knows why?
Most buildings on the island are too airtight.
Moisture cannot escape, gets trapped inside the wall, and leads to cool surfaces, mold, and an unhealthy indoor climate.
👉 The reason lies in the sd-value.
Once the sd-value exceeds 0.14 m, the material is no longer vapor-open.
What works in Central Europe often fails under Mediterranean conditions —
causing moisture buildup, salt efflorescence, and long-term structural damage.
In this new post, we explain:
➡️ Why Cyprus’ climate demands vapor-open construction
➡️ What the sd-value really means
➡️ Which wall and roof assemblies prevent moisture and ensure durability
💡 Building physics determines the health and lifespan of your property –
not just the design.
