Abstract: The present invention relates to a low-flammability shingle comprising at least one double-sidedly bituminized textile sheet material to whose surface has been applied a pulverulent or flaky flame protectant at least single-sidedly, and to roofs comprising these shingles.

Abstract: There are described a dimensionally stable laminate whose surfaces are formed by spunbonded webs and comprising at least two layers of spunbonded and at least one laid layer of reinforcing yarn, the laid layer or layers each being disposed between two layers of spunbonded and having a thread density of from 0.5 to 3 threads/cm, spunbonded and laid layers having been joined together by needling at about 20-70 stitches/cm2, a process for manufacturing this laminate, and its use for manufacturing roofing sheets and roof sealing sheets.

Abstract: There is described a bituminous roofing underfelt comprising a spunbond of polyester, in particular polyethylene terephthalate, filaments having a filament linear density of 1-8 dtex embedded in a bitumen matrix, wherein the weight of the bitumen accounts for from 40 to 90% and that of the spunbonded for from 10 to 60% of the basis weight of the roofing underfelt, and the spunbond is consolidated by a meltable binder whose melting point is below the processing temperature of the bitumen used in making the bituminous roofing underfelt and which is present in the spunbonded in a weight proportion of 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 spunbond present therein.
