Abstract: The present invention concerns a method for heat insulating a building surface with insulation boards, wherein each insulation board has two parallel main surfaces and four side surfaces connecting the two large surfaces, whereby the insulation boards are arranged adjacently on the building surface with each insulation board having a lowermost of the main surfaces facing the building surface, wherein each insulation board is divided into an upper part and a lower part with an interface that is substantially parallel with the two main surfaces, and wherein the method comprises the steps of arranging an insulation board on the building surface and then shifting the upper part of said insulation board a distance to at least partly cover a lower part of at least one neighbouring insulation board. The invention also concerns an insulation board for use in the method.
