How Do I Insulate a Wall Without Losing Internal Space?

Traditional internal wall insulation — rigid boards on battens — typically consumes 50–100mm of internal space per wall. In small rooms, existing buildings, plant rooms and commercial spaces, that space loss is often unacceptable. Yet the wall still needs thermal improvement to prevent condensation and cold surfaces.

A spray-applied natural cork thermal coating offers a way to improve the thermal behaviour of a wall without significant space loss. Applied in thin layers — typically a few millimetres — it adds a thermal layer directly to the wall surface, raising its internal surface temperature and reducing the conditions that lead to condensation.

By improving the thermal behaviour of the cold wall surface, an appropriate VIPEQ cork-enhanced thermal coating can help raise its surface temperature with minimal loss of internal space — and without the battens, frames and cavities that rigid boards require.
