That is why we started looking for other, out of the box, solutions. We came across a product called Spray Cork, cork but applied in spray form. It is a mixture of 80% cork granules and 20% water-based paint that comes in many color options. It’s surface is soft to feel and textured. It feels warm compared to the steel.
Spray Cork is waterproof but breathable and allows vapour to move through the material. It seals the surface completely so that there are no warm- or cold bridges. Cork is environmentally friendly and has very good insulation properties.
Spray Cork is mainly used for insulating homes on the outside, with very good insulation against sun, rain and frost. It can last decades on the outside and that will probably be even much better when applied to the inside.
