The covering comprises a large number of strips of timber fixed by means of clips or other components to a supporting framework fixed to the surface to be covered and is characterised in that the edges of the greater sides of the strips are partially asymmetrical, having an arrangement of mating projections and recesses and being capable of engaging in one another while leaving an intermediate gap and in such a way that the projecting upper edge of one of the profiles overlaps mating projections of the adjacent strip situated therebelow, preventing the base on which is fixed the covering or the accessories for the fixing thereof from being seen from the visible face of the covering.
