Definitions

  • the present invention refers to an insulation material element, according to preamble of claim 1 .
  • Such a “clamping felt” is known, for example, from DE 36 12 857 and is being successfully used for many years, especially for insulation purposes between rafters in vertical roofs.
  • a glass wool felt is being used, whose fibers are being obtained by internal centrifugation, according to the centrifuging basket process, bound with a binding agent quantity of approximately 6 to 7 weight % (dried, relative to the fiber mass), which is increased with respect to conventional glass wool, and the gross densities with nominal thickness of such insulating material sheets produced is between 10 and 30 kg/m3.
  • the felt sheet produced is rolled up with an average compression of 1:5 as a roll felt and, compressed in this fashion, it is being packed in a foil.
  • the foil is cut and the roll felt, as a result of its internal tension, rolls out in the form of a plane insulating material sheet with plate-like character, in a certain nominal thickness. From this rolled out insulating material sheet, normally supported by marking lines foreseen transversally to the longitudinal direction of said insulating material sheet, it is possible to cut off plates corresponding to the local width of a rafter area, which are then being mounted into said rafter area transversally towards the production and roll up direction (“The plate from the roll”).
  • the cutting procedure takes place with a certain excessive measure, so that during introduction into the rafter area, the plate segment is laterally compressed against the rafters, which is reinforced by the relatively high tensions then arising inside the clamping felt, in the form of clamping forces, which, by friction at the contiguous rafter area, avoid falling of said plate segment. From this clamped assembly originates the expression “clamping felt”.
  • the insulation material sheet there are also insulating plates made of mineral wool and being clamped between rafters available that feature marking lines, which serve here as a cutting aid for inserting the insulation material plates between the rafters.
  • Said roll felt sheet also has to be manufactured with a certain excessive thickness, in order to insure that after rolling out, the sheet effectively attains the nominal thickness, required for assembly of the clamping felt plates. It must be observed, in this case, that opening of the roll does not take place immediately after packing, but after a warehousing period at the manufacturer, in the shop or consumer, comprising weeks or months. During this period, the internal tension of the material may progressively be lessened, as a result of aging factors, so that the insulating material sheet for the clamping felt, when being rolled out, does not recover its original thickness as desired, as would occur when the roll is immediately opened after its production.
  • This possibly reduced resetting feature with the passage of time is being considered by am excessive thickness during the production phase.
  • This excessive thickness which in addition to aging phenomena, also considers a partial fragmentation of fibers during the roll up procedure, as a consequence of the compression feature, is highly important. So, a clamping felt with a nominal thickness of 160 mm, may require a production in a thickness of 200 mm, in order to insure that also months later a resetting to the nominal thickness of 160 mm takes place surely.
  • clamping felts of rock wool are known (DE 199 104 167), with the rock wool being produced in the so called nozzle blowing process or by means of other centrifuging, eventually with the so called cascade centrifuging process.
  • the conventional rock wool fibers thus obtained consist of relatively short, however thick and therefore comparably less elastic fibers with a bead portion, i.e. a portion of not fiberized material of 10 to 30% of the fiber mass.
  • the beads are of non-defibrated material, therefore rougher fiber components.
  • the gross densities of this material are practically above 25 kg/m3, and the binding agent content of these clamping felts of conventional rock wool, compared to clamping felts of glass wool, with eventually 2 to 3 weight %, is relatively low.
  • the integration of binding agent is comparable to the integration which takes places with clamping felts of glass wool.
  • clamping felts of conventional rock wool in the way they have to be rolled for transportation in the form of roll felts, before the rolling up station, are eventually recompressed and decompressed, in order to render them more “elastic”. With such an elastification by means of application of pressure, however, there will forcibly result a fiber rupture.
  • a gross density of approximately 40 to 45 kg/m3 is required, while with the same thermal conductivity group, with glass wool material, a gross density of less than 20 kg/m3 is being attained.
  • a clamping felt plate of conventional rock wool felt is at least twice as heavy as a plate of conventional glass wool felt, which is negatively observed vis-a-vis the clamping condition, based on the higher specific weight of the rock wool felt.
  • a characteristic feature of differentiation between glass and rock wool as subgroups of the category of mineral wool consists in the alkali/earth alkali mass relation of the composition, which in the case of rock wool is ⁇ 1 and in the case of glass wool >1.
  • conventional rock wool has a high portion of CaO +MgO of 20 to 30 weight % and a relatively low portion of Na2O and K20 of approximately 5 weight %.
  • conventional glass wool on its turn, features earth alkali components of approximately 10 weight % and alkali components above 15 weight %.
  • the invention is distinguished by an alkali/earth alkali mass relation of the mineral fibers of ⁇ 1 and a fine fiber structure of the insulating element, determined by the factors of average geometric fiber diameter ⁇ 4 ⁇ m, gross density in the range of 8 to 25 kg/m3 and a binding agent portion in the range of 4% to 5,5 weight %, referred to the fiber mass of the insulating material element.
  • the fibers Based on the chosen alkali/earth alkali mass relation of ⁇ 1, the fibers evidence a high temperature resistance, similar to conventional rock wool fibers.
  • the fine fiber structure is essentially used due to the fact that fibers with an average geometric fiber diameter of ⁇ 4 ⁇ m are being used.
  • Such a fiber structure may also be attained with glass wool, however as compared to rock wool, it is considerably less temperature resistant.
  • the range of the average geometric diameter of conventional rock wool fibers is normally above 4 to 12 ⁇ m, so that the fibers are configured in relatively coarse fashion.
  • this structure may be adjusted to a lower gross density, and the gross density range, according to the invention, is from 8 to 25 kg/m3 for the desired usage of the clamping felt.
  • the insulating element is distinguished by a satisfactory insulation capacity.
  • the use of a preferentially organic binding agent may be reduced with the product according to the invention, as compared to glass wool, i.e. to a range of 4 weight % up to 5,5 weight %, preferably to a range of 4,5 weight % until 5 weight %, with which the applied fire load is being reduced, without negatively affecting the clamping behavior.
  • the insulation material element is sufficiently stiff. In the case of an insulation material sheet this is at the same time windable up to a roll without damaging the fibers.
  • the insular mineral fiber plate, cut off from the roll, is thereby sufficiently rigid for clamped integration between beams, i.e. rafters.
  • both the insulation material sheet and the insulation material plate are homogenously formed in the range applicable for the clamping effect, meaning that they feature the same density relations via the cross section.
  • the fibers according to the invention distinguish themselves as a result of the alkali/earth alkali mass relation of ⁇ 1 by the high temperature resistance and correspond, therefore, to the properties of conventional rock wool. Based on the finer fiber structure, however, and on the comparably lower gross density, there results for the structure according to the invention, a far more elastic behavior.
  • the insulation material sheet, before the roll up step does not require special treatment, eventually a fulling or flexing process, so that the compression and decompression steps, required with conventional rock wool, are no longer needed.
  • the mineral wool felt, during the roll up phase is being compressed to a roll with a compression ratio of 1:3 to 1:8, preferably from 1:4 to 1:6.
  • the clamping felt of the invention distinguishes itself by an outstanding resetting behavior, so that the required insulation material element advantageously may be produced with a comparably lower excessive thickness, than this takes place with conventional products.
  • This resetting behavior remains preserved also after longer warehousing periods of the rolled up roll felt, so that the insulation material sheet, when being used, again is being reset advantageously to its nominal thickness, which is important also vis-a-vis the technical insulation features.
  • insulation material sheet has to be broadly seen and it comprises a never-ending sheet, as it is coming out of the hardening oven for further mechanical processing, meaning edge-trimming, cut-outs, etc. therefore also to a roll convertible, meaning rolled insulation material sheets, which can be separated on the site at the right distance to the plates.
  • the limiting parameter is a minimum gross density, technically predetermined by the hardening oven, being defined from the initiating configuration of heterogeneous phenomena in the fleece by the passage flux of hot air during the hardening process.
  • clamping felt of the invention it is also possible to attain fire protection constructions of at least a fire resistance category EI 30 according to EN 131501, where the clamping felt is integrated between beams, such as roof rafters, without additional interior lining.
  • the mineral fibers for the insulation material of the invention may especially be produced by internal centrifugation according to the centrifuging basket procedure, with a temperature at the centrifuging basket of at least 1.100° C., with the obtention of fibers with a fine fiber diameter in the indicated range.
  • Mineral wool fibers, produced with the internal centrifugation according to the centrifuging basket process are known from EP 0 551 476, EP 0 583 792, WO 94/04468, as well as from U.S. Pat. No. 6,284,684, to which reference is expressly being made with a view to additional details.

  • the frequency distribution can be determined with the microscope, based on a wool sample.
  • the diameter of a large number of fibers is being measured and applied, resulting in an oblique distribution towards the left side (see FIGS. 2, 3 and 4 ).
