The invention relates to a hydrophobically finished roof lining which allows diffusion. The roof lining comprises a membrane (3) which is impermeable to water but is, however, permeable to water vapor and which is joined on one side or preferably on both sides to a covering consisting of nonwoven material (1, 2) using a thermoplastic hot-melt-type adhesive. In order to improve the endurance of the hydrophobic finishing, the invention provides that a constituent of the hot-melt-type adhesive (4, 5) is a waterproofing agent which has approximately the same melting temperature as the hot-melt-type adhering constituent, whereby the melted hot-melt-type adhesive material exhibits a property which enables it to suffuse the covering consisting of non-woven material. |
