NOVELTY - Composition of an insulating material comprises expanded polystyrene (EPS) granules and a binding agent, characterized in that the binding agent comprises water, cement and nanocellulose. USE - Composition for solid insulating material (claimed). ADVANTAGE - The composition has a sufficiently high thermal insulation value and at the same time is composed of readily available components based on natural materials that are easy to recycle. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a kit comprising spatially separated components for production of an insulating material, which comprising a first component A and a second component B, where the first component (A) comprises EPS granules and the second component (B) a binder, characterized in that the binder is water, cement and nanocellulose; and (2) a method for manufacturing a solid insulating material in which EPS granules are equally distributed in a binding agent, resulting in a liquid insulating material, after which the liquid insulating material is cured into a solid insulating material, characterized in that the binding agent which comprises water, cement and nanocellulose.
