🔬 What Are Microspheres – and Why Do They Matter in Thermal Paint?

You’ve probably heard us mention that Bloktherm® uses microsphere technology. But what exactly are microspheres – and what makes them so effective at insulating your home?

Let’s break it down.

🧪 What Are Microspheres?

Microspheres are tiny, hollow ceramic balls – so small that you could fit hundreds on the tip of a pin.
They’re lightweight, heat-resistant, and extremely durable.

When mixed into a coating like Bloktherm®, they create a dense network of air pockets within the paint layer – and that’s where the magic happens.

🌡️ How Do They Work?

These air-filled spheres act like mini-insulation chambers.
When applied to a wall, they:

• Reflect heat back into the room instead of letting it escape

• Block thermal bridges (the cold spots that attract condensation and mould)

• Improve wall surface temperature – making rooms feel warmer and drier

• Create a breathable, yet protective barrier

The result? A coating that looks like paint, but works like a smart insulation layer.

🎯 Why Not Just Use Standard Paint?

Standard paint only decorates – it does nothing to improve energy efficiency.
Microsphere-based coatings combine aesthetics with function – giving you both comfort and protection in one layer.

With Bloktherm®, you don’t just repaint – you upgrade your walls.
