Thermal cork spray is a natural exterior coating that creates an insulating, breathable, and protective layer on your walls.
The natural thermal performance of cork can reduce heating bills by up to 30 percent and is proven to be seven or eight times more insulating than traditional lime and sand renders.
It is water resistant, fire rated to Euro class B, breathable, and designed to help prevent mould and damp while improving appearance. Acting as a protective barrier, it shields your property from rain, wind, and UV exposure while maintaining long-term exterior durability.
