Abstract (en)

A film or foil of ethylene vinyl alcohol with a thickness of between 5 mu m and 50 mu m is used as a water vapour barrier or underroof (15) for buildings. At least parts of the opposite side surfaces of the film or foil are exposed to moisture of the ambient atmosphere. It is important that the vapour diffusion resistance of a vapour barrier is as low as possible under humid conditions and as high as possible under dry conditions. A film of ethylene vinyl alcohol has a very wide diffusion resistance range and provides a more durable vapour barrier or underroof as the material has excellent weather ability. Preferably, the film or foil of ethylene vinyl alcohol has a thickness of between 5 mu m and 50 mu m. <IMAGE>
