Abstract (en)
[origin: EP0590629A2] There is described a bituminised (bituminous) roofing underfelt (under-roofing felt, sarking, underslating felt) comprising a spunbonded (nonwoven) of polyester, in particular polyethylene terephthalate, filaments having a filament linear density (individual titre) of 1-8 dtex embedded in a bitumen matrix, characterised in that the weight of the bitumen accounts for 40 to 90%, and that of the spunbonded for 10 to 60%, of the basis weight of the roofing underfelt, and in that the spunbonded is consolidated by a meltable binder whose melting point is below the processing temperature of the bitumen used in making the bituminised roofing underfelt and which is present in the spunbonded in a weight proportion from 5 to 20% of the total weight. The spunbonded preferably bears an embossed pattern, for example a plain-weave embossment. There is also described a process for manufacturing the roofing underfelt and the spunbonded present therein.
