Owning or maintaining a listed home is a privilege – but also a challenge.
Many historic properties were built long before modern insulation standards, leaving them vulnerable to:

  • Heat loss through walls and ceilings

  • Persistent condensation

  • Damp and mould problems

And because listed properties are protected, traditional insulation methods like external cladding or heavy internal modifications are often not an option.

🧱 The Problem: Old Walls, Modern Expectations

  • Solid brick or stone walls are beautiful but highly porous.

  • Minimal or no insulation means rapid heat loss.

  • Heating costs rise, comfort drops – and mould thrives on cold surfaces.

At the same time, any solution must respect the original structure and be reversible, breathable, and non-invasive.

🎯 The Solution: Thin-Layer Thermal Insulation Systems

At TopTherm, we offer advanced thermal coatings that:

  • Are applied like paint – no major structural changes

  • Reflect heat back into the room

  • Raise wall surface temperatures – reducing condensation risk

  • Allow the wall to breathe – preventing trapped moisture

  • Are thin, discreet, and fully compatible with listed home requirements

Our systems like Bloktherm® INTERIOR and WARM LAYER offer a practical, minimally invasive upgrade for heritage buildings.

✅ Why Smart Coatings Make Sense for Listed Properties:

  • No visible external alteration

  • No heavy insulation boards

  • Breathable and vapour-permeable

  • Quick to apply with minimal disruption

  • Improve comfort and help reduce energy bills

🔍 Case Example:

In traditional stone-built cottages, applying a breathable thermal coating on internal walls can reduce heat loss by up to 25% without changing the appearance of the room – all while fighting condensation and damp.

🛡️ Respect the History. Upgrade the Comfort.

Listed homes deserve to be preserved and lived in comfortably.
Smart insulation coatings provide a respectful, effective solution for a new generation of heritage homeowners.
