Internal Coating

High performance insulation for internal walls

CorkSol SprayCork is the ideal solution for internal as well as external coatings.

As a natural product cork is breathable and has great thermal properties so can be used internally to solve issues with damp and mould.

Internal Wall Insulation

Our approved applicators use a thin layer of spray-applied natural cork, one of the world’s most incredible and sustainable natural resources. This can then be over skimmed and painted giving you the freedom to decorate over it as you please.

  • Sustainable and breathable natural product
  • Final coating is only 6-8mm thick so no need to worry about replacing fixtures and sockets etc.
  • Can be plastered over with a thin layer for a smooth finish
  • You are left with an invisible solution that mould or damp cannot form on
