  • the present new development relates to roofing material, which is formed from one or more bituminous layers and is also provided with a plastic insert and / or a reinforcement, in particular of plastic and / or glass.
  • roofing material Such a roofing material is known.
  • the insert and / or reinforcement is formed for example by a polyester fleece and / or glass fleece or a fabric or cloth, or a combination of these materials. This is passed through a bath of molten bituminous material, with the bituminous material settling on the opposite sides of the liner or reinforcement to form a coating.
  • the insert and / or reinforcement necessarily has a melting point, which is considerably higher than the temperature of the bituminous coating bath of about 180 ° C, through which it is passed with a corresponding force through.
  • a melting point which is considerably higher than the temperature of the bituminous coating bath of about 180 ° C, through which it is passed with a corresponding force through.
  • bitumen To be able to process bitumen into a bituminous roofing membrane, it has to be liquid. When bitumen is heated to melting temperature, for example to 50 ° C or 60 ° C, it becomes soft. It is therefore not liquid and not yet suitable for processing in a roofing membrane.
  • the materials that are generally used for the deposits behave differently. When the melting temperature is reached, these materials almost immediately turn into a liquid form. This is partly due to the fact that they have a too low mass, the z. B. at 100 g / m 2 .
  • the temperature at which the bitumen becomes liquid depends on the type of bitumen.
  • filler and modifier are added to the bitumen and the bitumen is modified, it produces a bituminous mass, ie a bitumen compound that has a high viscosity.
  • a type of modified bitumen and thus a bitumen compound with numerous additions fillers, modifier
  • the bitumen compound may already be liquid at a lower temperature, say at 100 ° C.
  • the processing temperature of the corresponding bitumen type is thus 100 ° C.
  • the melting point of the plastic insert is about 250 ° C, as is the case with the often used polyester fleece.
  • the bituminous coating bath usually has a processing temperature of about 180 ° C.
  • the life of the bituminous roofing material is about 25 to 30 years, after which, for example, a cracking occurs or the roof covering must be removed for other reasons.
  • the bituminous components remain almost untouched during this period and are thus ideally suited for recycling.
  • the waste of the roofing material in addition to bitumen and bituminous mixtures, also contains the material of the deposits or reinforcement, this is often burned. This has a very harmful effect on the environment and leads to a high C0 2 emission.
