Description	In the European Standards EN 15026 and EN ISO 13788, moisture transport in building envelopes is assumed one dimensional. In fact, three-dimensional moisture transport occurs due to layer perforation or building assembly details. The article is focused on cases of flat roofs where the vapour barrier is perforated. Water vapour permeability measurement of different vapour barriers with different degrees of perforation is done by the wet-cup method. Results are presented. A significant increase of moisture transport is found through vapour barriers which are perforated. A note on setting the apparatus to measure materials with very high water vapour resistance factor is presented. Finally, based on the results we discussed new recommendations to design more efficient flat roofs and avoid future failures.
