Definitions

  • the invention relates to a lower cover plate for use as a substructure in roof structures.
  • Such panels are generally placed on the rafter construction and fastened there before the actual roofing is applied.
  • such plates are also assigned to noise and heat insulating properties.
  • DE 4322745 describes a roof insulation board with a mountable on the rafters of a roof vapor-permeable insulation board, which is provided with a waterproof, vapor-permeable film to ensure waterproofness, for example, in driving rain and consists of compressed polyester fibers. Due to the waterproof, vapor-permeable film, however, this solution entails dangers such as, for example, the delamination of the layers or even the formation of holes in the film during the laying phase. When processing such panels, special care must be taken to avoid damage to the roof insulation panels.
  • an insulating element is disclosed with a walk-in cover plate, is fixed under a continuous insulating plate, are formed in the longitudinal and transverse ventilation channels.
  • the insulating plate consists for example of PU foam, stone and mineral wool or wood fiber material, while for the cover plate wood-based panels, gypsum and gypsum fiber boards are used.
  • the object of the present invention is to avoid the mentioned disadvantages of the prior art with the features mentioned in claim 1 and in the subclaims.
  • the lower deck according to the invention is able to significantly increase not only the basic requirement for accessibility and permanent waterproofness, but also the noise insulation and the thermal insulation despite the small thickness of the panel in the roof space.
  • this bottom cover plate of a carded, cross-laid nonwoven fabric of synthetic staple fibers which is mechanically consolidated and compacted, as well as thermally consolidated.
  • thermal insulation measures are carried out in the construction of new buildings and refurbishments.
  • old building renovations are by the rafter height
  • limits are set for the height of the insulating layer between the rafters.
  • the rafter height is often limited by the financial framework of the client.
  • the legislation has narrow limits here, which must be complied with in order to achieve a permanent insulation from an economic point of view.
  • An inventively designed lower deck plate makes it possible to move a portion of the thermal insulation in the outer area of the roof structure, so that it is not necessary to work with large thicknesses especially in the renovation of old buildings in the interior.
  • the undersheet according to the invention comprises a mechanically formed nonwoven made from a mixture of thermoplastic and / or duroplastic staple fibers with melt fibers, which is first mechanically consolidated and compacted. An adjoining thermal treatment activates the melt fibers, so that after cooling of the material results in the inventive rigid bottom cover plate.
  • the raw materials used should also be a To provide permanent mold resistance without this being due to a chemical treatment.
  • one or both sides of the lower cover plate is hydrophobic. This is achieved according to the invention by the use of at least one hydrophobic fiber type. Melt fibers are then used in the fiber mixture. In addition, other fibers are used with large fiber diameters.
  • melt fiber is used in the present specification synonymously for fibers which are usable for the thermal consolidation of nonwovens.
  • such fibers contain thermoplastic regions which have a lower melting point than the remaining non-woven fabric forming fibers.
  • These fibers may consist entirely of a low melting point polymer, but may also be so-called bicomponent side / side or core / sheath type fibers.
  • polymers all common variants of polyesters, polyamides or polyolefins are suitable. Also fusible fractions with higher crystalline proportions can be used.
  • the proportion of melt fibers according to the invention is at least 40 weight percent.
  • the fibers have a commercial crimp.
  • the fiber diameter of the melt fibers used is between 10 and 60 ⁇ m.
  • the hydrophobic fibers have a smaller compared to the other fibers in the fiber mixture fiber diameter.
  • the fiber diameters used are included maximum 20 ⁇ m, preferably less than 18 ⁇ m.
  • these fibers are called fine fibers.
  • Such fibers may consist of thermoplastic polymers, but thermoset polymers are also conceivable.
  • the fine fibers have a crimp, which can be either two-dimensional but also three-dimensional nature. By crimping the fibers have a more or less strong restoring force against mechanical loads. The greater the crimping, expressed in terms of number of crimps / cm, the greater the restoring force. Fine fibers which have a number of at least 4 crimps per cm are suitable according to the invention; fibers having greater than 6 sheets / cm are preferred.
  • This restoring force can be further influenced by the polymer forming the fibers.
  • Suitable are polyolefins, polyamides, polyacrylics and polyesters. Due to the good recovery properties, preference is given to fibers of linear macromolecules whose chain consists of at least 85 percent by weight of the ester of a diol with terephthalic acid. They are referred to in the context of the present invention as polyester fine fibers.

During this dry phase, most of the moisture in the building diffuses outward through the roof area. Depending on the temperature conditions, it may lead to the formation of condensation on the Unterdeckpatten.

The stone presses into the surface and perforates the film, the roof has defects. This is also the case with chemically bonded wood fiber boards. Once there is a partial overload, such a bottom plate is disturbed in its integrity and vulnerable to impinging water.
