Heritage & Traditional Buildings — Breathable Thermal Coating
Vapour-permeable thermal coating for solid stone walls, lime walls and historic buildings. By raising surface temperature while allowing the building to breathe, an appropriate VIPEQ thermal coating helps control condensation in traditional buildings.
Heritage and traditional buildings — solid stone walls, lime-rendered facades, historic masonry — behave very differently from modern cavity-walled construction. Solid walls have no cavity to break the thermal path, so heat flows directly through the masonry, creating cold internal surfaces that fall below the dew point and condense moisture.
Trapping moisture in traditional buildings is one of the greatest risks of retrofit. Impermeable insulation and modern membranes prevent the building from breathing, driving moisture into the masonry and causing damp, decay and freeze-thaw damage. Any thermal treatment for a heritage building must be vapour-permeable.
A breathable thermal coating applied to the internal face of a solid wall raises its surface temperature and reduces condensation, while remaining vapour-permeable so the masonry can continue to breathe — the same principle that makes lime render suitable for traditional buildings. This links directly to VIPEQ cork-enhanced systems, which are naturally vapour-permeable.
Why Breathability Matters in Heritage
Traditional buildings were designed to breathe. Any thermal treatment must be vapour-permeable — otherwise moisture is driven into the masonry, causing the damp and decay that ruin historic fabric. A breathable thermal coating raises surface temperature without trapping moisture.
Condensation forms when warm, moisture-laden air meets a surface whose temperature has fallen below the dew point. By improving the thermal behaviour of a cold surface, an appropriate thermal coating can help raise the internal surface temperature and reduce the conditions that lead to surface condensation.

Thin-film, breathable thermal improvement suitable for sensitive heritage retrofit projects.
VIPEQ's cork-enhanced thermal coating systems are spray- or trowel-applied directly to the substrate, forming a thin, flexible, vapour-permeable thermal layer that conforms to irregular surfaces — steel, concrete, masonry and timber — without rigid boards, battens or significant loss of internal space.
