The invention relates to a multi-layered building wall provided with an inner wall comprising a building inner surface and an outer surface, and a façade layer forming the outer side of the building wall. The aim of the invention is to provide a multi-layered building wall, wherein damp penetrating the wall from the inside or the outside is reliably drained off. To this end, a draining vapor barrier (6) having a cavity-forming structure on both sides and an SSBD/SB-value=50 m corresponding to an equivalent air layer thickness is arranged on the outer surface of the inner wall (4).
