  • hard roofing is used in the State building regulations and in the guidelines for the Use of flammable building materials explained in more detail. As a result, there is a so-called hard roof, if the component to be used as roof skin against flying fire and radiant heat to a certain extent resistant is. The measure is defined by the test DIN 4102, part 7 "Hard roofing”.
  • a very serious disadvantage of the known component is, for example, that the connection of the Glass fabric with the top of the plastic part prolonged weathering is not permanent enough.
  • the Glass fabric coating takes off due to its wicking relatively much moisture on it, causing it to Signs of delamination between plastic plate and Coating can come.
  • the glass fiber top layer is very dirty strong because it is relatively rough.
  • DE-OS 40 42 265 discloses a translucent Roof element, which is between a transparent Outer plate and a transparent inner plate, the is arranged parallel to the outer plate, a translucent Has intermediate layer, which is a glass fiber and / or has a glass mat.
  • WO-A-92/09760 shows translucent thermal Insulation materials with a mineral wool base (glass fibers) with a top layer (coating layer) as Protection from dust and putrefaction.
  • the non-flammable, against flight fire and Radiation heat resistant coating is not or only exposed to very little weather; costly modifications to the coating can eliminated or reduced accordingly; Adhesion problems due to moisture absorption (wicking) with outside weathering are minimized; the association of Plastic plate with the coating is simple producible and the requirements according to DIN 4102 are also over an extended timespan without significant aging of the translucent component for the hard roofing.

  • the woven, knitted, crocheted or Fleece also from other materials, such as. B. asbestos, Mineral fiber and metals exist.
  • the fabrics are advantageously covered or impregnated with a layer of thermoplastic, in particular acrylate, polyurethane or PVC, at least on the side with which they are to adhere to the plates serving as the basic structural element.
  • a film generally known as weatherproof, in particular PTFE or PVF, can preferably be laminated onto the component.
  • weatherproof film can, if desired, also be laminated onto the coating, in particular the fabric or nonwoven, to be precise on the side of the coating facing away from the component.
  • a film generally known as anti-adhesive, in particular made of PTFE or PVF.
  • the coating of the component can advantageously also contain flame-retardant substances.
  • the preferred way to manufacture the components is that the non-flammable fabric, knitted fabric, tangle or Fleece, which consists in particular of glass fibers, during the Manufacture of plates in a generally known manner done, run into the calibration and on the Bottom of the plates sticks.
