Abstract: The present invention concerns an insulating wall system for a building structure, wherein the wall system comprises a first wall having an exterior surface with insulation material attached to the exterior surface of the first wall by elongated fastening members extending through at least one wall member of a second wall and the insulation material and being fixed to the first wall, wherein the elongated fastening members are mounted substantially perpendicular to the exterior surface of the first wall and that the elongated fastening members are mounted pre-stressed with a predetermined amount of tension so that frictional forces between the insulation material and the exterior surface of the first wall and the inner surface of the second wall, respectively, are established. A wall system according to the invention includes fewer components and may provide an improved insulation as the components constituting thermal bridging may be reduced.
