A supporting guide rail for a scaffold, the guide rail being an elongated horizontal member with a top edge onto which the scaffold is hung and along which the scaffold moves horizontally thereon, to enable the scaffold to be movable over a part of a facade of a building, the facade exhibiting a plurality of facade cladding members, wherein one cladding member is movably attached to the building by telescopic guides, so as a) in an outer, active position spaced from the facade to form said guide rail, and b) in a retracted, inactive position to be located in a space between an upper adjacent cladding member and a lower adjacent cladding member to thereby form part of the facade along with the other facade cladding members, a lower edge of said upper adjacent cladding member having in a groove thereof a seal element, and wherein in said retracted, inactive position of said one cladding member the seal element seals against an upper edge of said one cladding member; and wherein the telescopic guides each comprise a guide rail supporting bracket telescopically movable in a guide having a mounting bracket attached to the building, the supporting bracket having a stop member movable in an oblong slot of the mounting bracket between outer and inner ends thereof, so as to define said active and inactive positions of said one cladding member, respectively.
