The casting compound layer forms the first planar surface of the insulation tile and the insulation material layer forms the second planar surface of the insulation tile. Furthermore, the insulation material layer of the insulation tile comprises grooves in the area of the planar surface which will be against the casting compound layer. The insulation tile according to the invention can be used in floor, roof and wall structures. ## Claims ### Claim 1 An insulation tile having a first planar surface, a second planar surface and four side surfaces, the insulation tile consisting of: a casting compound layer having a first and a second surface and four side surfaces, and an insulation material layer having a first and a second surface and four side surfaces;
