Definitions

  • the invention relates to a mineral fiber web with an insulation layer made of soft, loose mineral fiber felt according to the preamble of the claim.
  • the thermal insulation layer is arranged directly on the uppermost ceiling structure and is therefore on the warm side of the roof, while on the outside of the thermal insulation layer only the roof covering, which protects against the weather, is arranged without the interposition of a ventilation-capable air layer.
  • the roof covering or roof skin is rear-ventilated and the thermal insulation layer lies at a distance from it on the inside of the roof structure. The air gap between the outside of the thermal insulation layer and the roof covering is necessary, especially in a humid indoor climate, in order to convert condensation water on the outer, cold side of the thermal insulation layer back into the gas phase by passing, drier ambient air to avoid damaging moisture accumulation.
  • a vapor barrier or vapor barrier is arranged on the warm inside of the thermal insulation layer.
  • the mineral fiber webs with an inner liner are usually laid out of aluminum foil in a thickness which is reduced compared to the overall height of the rafters; Mineral fiber webs of this type are manufactured and sold by the applicant under the name ROLLISOL (registered trademark).
  • the required air gap for roof ventilation or roof battens is created, while the membranes are fastened to the inner surfaces of the rafters via protruding edge strips of the lamination membrane, the edge strips of adjacent membranes overlapping one another nailed or pinned to the inside surface of the rafters.
  • a major problem in connection with such mineral fiber webs arises from the fact that the final height of the loose insulating material web in the unloaded, aged state, as it is ultimately installed between the rafters, cannot be predicted exactly.
  • webs made of extremely loose mineral fiber felt with a nominal bulk density of 15 kg / m * are produced with a considerable excess over the nominal thickness, with a nominal thickness of 100 mm, for example, with an actual thickness of more than 150 mm on the production line.
  • the nominal thickness is determined by applying a test load to DIN 18165 Part 1 on the web is, which compresses the web significantly, especially in the case of extremely looser structure, and must first result in the nominal thickness of 100 mm.
  • the production must be designed so that at least the nominal thickness is retained even under the test load; Without a test load, i.e. in a completely unloaded state, this regularly leads to greater thicknesses due to springs, which cannot be exactly predetermined. If the mineral fiber web delivered in roll form under tension is opened and rolled out at the assembly point with a nominal thickness of, for example, 100 mm, the mineral fiber felt can certainly have a thickness of e.g. B. spring open 120 or even 130 mm and reach behind a corresponding rafter height during installation.
  • a gap of, for example, 4 cm height is to be provided for ventilation, then taking into account these fluctuations in thickness as well as tolerance fluctuations in the area of the rafters, a significant undersize would have to be chosen with regard to the nominal thickness of the mineral fiber web to be installed, in order to provide the important air gap provided for in the construction to actually get with certainty.
  • the installation specialist chooses a correspondingly low nominal height and the built-in mineral fiber web only springs slightly above the nominal height, the insulation height of possibly a few centimeters is lost in addition to the air gap, which in view of a usual rafter height of 15 cm or a little more is a very significant part of the theoretically possible insulation thickness.
  • the air gap can be added by insulating material by springing open accordingly, so that moisture can form.
  • the invention has for its object to provide a mineral fiber web of the type outlined in the preamble of claim 1, which is suitable for the thermal insulation of cold roofs and ensures sufficient rear ventilation without loss of thermal insulation thickness in any case, even with different spring properties of the mineral fiber felt of the insulating material web.
  • holding down devices are arranged in parallel, discrete zones running in the longitudinal direction of the mineral fiber web, the material on the bare surface of the insulation layer is securely held locally in the area of the holding down device at a defined distance from the lamination web. Between The rows of hold-down devices can spring up more, but depending on the lateral distance between the hold-down devices, the overall spring capacity is limited.
  • a precisely predeterminable distance remains between the head ends of the hold-down device and the supporting structure of the roof covering, which, in combination with the limited elasticity of the material on the bare surface, ensures sufficient ventilation either by leaving a desired ventilation gap over the entire width of the rafter spacing , or at least in the longitudinal direction of the web and thus of the roof, there are rear ventilation channels in the area of the rows of hold-down devices, via which moisture can be removed accordingly.
  • the distance secured by the hold-downs between their ends on the head side and the lamination web can be specified at or slightly below the nominal thickness.
  • the distance secured by the hold-down devices is selected, for example, around 10% - 20% below the nominal thickness, since the material between the hold-down devices can spring up relatively strongly, while in the case of larger bulk densities and, in particular, binder-free qualities with bulk densities of up to 60 or 70 kg / m ', the distance secured by the hold-down devices can correspond approximately to the nominal height or be only slightly less.
  • the lamination web 4 may consist of two metallic cover foils, in particular made of aluminum, between which reinforcing threads running in the longitudinal and transverse directions of the mineral fiber web 2 are glued.
  • single-layer metal foils such as, in particular, aluminum foils, single-layer foils or composite foils based on kraft paper or similar materials known or customary in the present context can be used to form the lamination web 4, provided that these can serve as a vapor barrier; a particularly high-quality vapor barrier in the area of the lamination web 4 is not important, since in the area of the bare surface denoted by 8 towards the battens there is in any case a ventilation gap 9 in which air can circulate and moisture can form.
  • Discrete zones hold-down device 10 are arranged, by means of which the adjacent fibers of the bare surface 8 of the insulation layer 3 made of mineral fiber felt are kept to a reduced thickness compared to the adjacent zones free of hold-down devices 10.
  • the height of the rafters measured in the vertical direction in the drawing may be 18 cm, while the nominal thickness of the mineral fiber web 2 is 15 cm.
  • the insulation layer 3 made of mineral fiber felt could unfold to a thickness of over 18 cm in the worst case, so that the space up to Battens 5 would be completely filled and no moisture could be removed by ventilation.
  • the hold-down devices 10 used in this example trap may have a height of 13 cm, so that their head end on the bare surface 8 is 5 cm from the battens 5.
  • the mineral fiber felt springs up between the rows of hold-down devices 10, but its spring-back capacity is limited by the adjacent head ends of the hold-down device 10.
  • Threads can also be used in the form of quilting seams, as is known per se for improving the strength and improving the homogeneous integrity of mineral fiber webs.
  • the insulation layer 3 is first provided with this and then the lamination web 4 is applied in a conventional manner to the insulation layer 3 treated in this way. This has the advantage that the vapor barrier effect of the lamination web 4 is ensured.
  • the hold-down devices 10 can reach through the lamination web 4, but this means that the lamination web 4 is coated with a rubber-like or viscoelastic material which promotes healing of punctures when the vapor barrier effect is to be restored.
  • the hold-down devices 10 can be produced with particular advantage by shooting in a flowable, solidifying material from the bare surface 8, as is explained in more detail in the parallel patent application P 34 38 417.0-16 by the same applicant, to which reference is expressly given in full terms for further details is taken.
  • the spring-up is sufficiently limited to the nominal thickness range even with low bulk densities or, through the formation of the channels 9a, even when the ventilation gap 9 is closed locally, spring-up ensures air circulation, so that extremely soft, loose mineral fiber felt can be used.
  • conventional binder-containing material it is therefore possible to work with low nominal bulk densities of less than 30 kg / m 3 , in particular less than 25 kg / m l and in particular at 15 kglm 3 , while correspondingly higher bulk densities must be expected for lower binder contents. as the ability of the binder to form a loose, relatively stiff structure from fibers then becomes increasingly less.
  • the height of the suspension between the hold-down devices 10 can be influenced in a suitable manner by their spacing.
  • Mineral fiber webs 2 according to the invention are not restricted for use on roofs, but can be used in any comparable problem cases if the degree of springing is limited, for example, to maintain an air gap and should be predeterminable.
