Claim:
A method of constructing a building, the method comprising: providing a skeleton for the building, said skeleton including at least upright building elements, each of the upright building elements having a side facing in a direction toward an outside of the building; placing at least one, lightweight, heat insulating and fire retarding wall element between each adjacent pair of said upright building elements which are positioned before the wall elements are placed, such that the wall elements completely fill the space between the upright building elements to form a complete wall, wherein each of the wall elements includes a front side facing toward the outside of the building and a back side that faces a direction that is opposite the front side, and wherein the front side of each of the wall elements is positioned further toward the outside than the side of each corresponding building element, and wherein at least some adjacent wall elements on each side of a corresponding upright building element abut each other on the front side facing in the direction toward the outside of the building; covering said upright building elements at least on the outside to provide at least a substantially closed outer wall surface; providing a cover panel in contact with first and second adjacent wall elements to form a substantially closed inner wall surface, wherein the cover panel is formed separately from the first and second adjacent wall elements and is placed after the first and second adjacent wall elements are placed and providing on each of the front side and the back side of the wall elements and in contact therewith, and at least on the outside of the upright building elements, a covering layer which has properties so as to provide at least fire-resistance to the complete wall, wherein the covering layer is placed after the wall elements are placed.
