Claim:
A timber covering for exteriors and interiors, the covering comprising: at least one fastening clip for affixing timber strips to a supporting framework, the framework being fixed to a surface to be covered; a plurality of strips of timber; the plurality of strips being mutually parallel and disposed in the same plane and comprising grooves in mutually opposed lateral edges for engaging edges of the fastening clip; wherein 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 in such a way that a projecting upper edge of a profile of a respective strip overlaps mating projections of an adjacent strip situated therebelow, thereby preventing a base on which is fixed the covering or accessories for the fixing thereof from being seen from a visible face of the covering and allowing the passage of water through the intermediate gap to the base.
