Definitions
- the present invention relates to a sealing member and a method of manufacturing a sealing member.
- the present invention relates to a sealing element which is provided for sealing a frame component, for example a window frame, with respect to a structural component, for example a roof region composed of roof shingles.
- a sealing element which is provided for sealing a frame component, for example a window frame, with respect to a structural component, for example a roof region composed of roof shingles.
- the prior art for example in the form of pleats, the possibility of forming an extension reserve, which allows the sealing element to extend in regions, in order to follow or counteract the distortions and undulations.
- a sealing element of this type is shown, for example, by EP 0 755 474 B1 and EP 0 942 1 09 A2.
- a sealing element with a sandwich structure in particular for sealing a frame element in relation to a building component, comprising:
- a filling layer comprising bitumen and / or a binder, which is arranged between the primary layer and the secondary layer.
- the bitumen-comprising flexible filling layer can be used to set a desired, comparatively large weight per unit area, which on the one hand is helpful during assembly and, on the other hand, in the mounted state causes its own weight, which supports a sealing functionality of the sealing element, so that advantageously can be dispensed with the use of lead-containing materials.
- the bitumen-containing filling layer contributes as the bituminous heavy layer for weight increase, comparatively thin primary layers and / or secondary layers are sufficient, which in turn advantageously reduces the proportion of the metal to be recycled. In this case, the reduction of the primary layer and / or secondary layer is further promoted by the fact that the primary layer is creped and does not pleat.
- Creping is understood by the person skilled in the art to mean, in particular, an irregular folding, in particular envelope folding, in which a folding height and a distance to the next fold are statistically distributed. Further, in a creping, a fold line is, for example, bent and not straight as in pleating.
- Suitable binders besides bitumen are, for example, ethyl vinyl acetate (EVA), butyl, polyethylene (PE), styrene-butadiene block copolymers (SBS polymers), amorphous polyalphaolefins (APAO), thermoplastic elastomers or similar materials.
- the sealing element is designed strip or strip-shaped and, for example, the creping is configured such that the creping allows an extension, in particular exclusively a unidirectional extension, along the longitudinal direction of the sealing element.
- the creping forms an extension reserve, which allows the sealing element to be stretched, at least in regions, if necessary, in order to counteract possible distortions or undulations during assembly of the sealing element.
- the creping of the primary layer extends over the entire sealing element or is embedded in the primary layer at regular intervals in the longitudinal direction.
- the primary layer is made of aluminum.

- the opposite crepe structures, ie folds, are different and can be positioned independently of each other.
- a degree of creping of the primary layer corresponds to the degree of creping of the secondary layer. It is also conceivable that the degree of creping of the primary layer differs from the degree of creping of the secondary layer.
- the filling layer comprising bitumen is designed such that it permanently elastically deforms during the stretching of the primary layer and / or the secondary layer, so that the stretch is maintained in the installed state of the sealing element and the renewed creping is prevented in regions. It is also conceivable that the creped areas of the primary layer and the secondary layer seen in the direction of layering overlap congruently or at least partially overlap. If the secondary layer is designed as an adhesive layer, the sealing element can be fixed in an advantageous manner by means of the adhesive layer on the building or on a Bauwerkskompo- component simply.
- the primary layer, the filling layer and the secondary layer adjoin one another directly and / or the sealing element consists, for example, exclusively of primary layer, filling layer and secondary layer.
- the filling layer comprises a filling material, in particular an iron oxide, heavy spar, strontium ferrite, limestone meal and / or quicklime comprising filling material.
- the filling material is composed such that a basis weight assumes a value between 2 and 10 kg / m 2 , preferably between 4 and 8 kg / m 2 and particularly preferably between 5 and 7 kg / m 2 .

- the primary layer and / or secondary layer has a thickness measured in the laminating direction of 0.02 to 0.1 mm, preferably 0.03 to 0.075 mm or a thickness of substantially 0.05 mm.
- the sealing element has thinner metal layers compared to those with pleats whose thickness is typically 0.15 mm.
- the thicknesses for the primary layer and / or the secondary layer are those thicknesses which are measured prior to creping or as they are before creping.
- the thickness is chosen so large that sufficient rigidity, dimensional stability and weather resistance can be ensured for the sealing element.
- the primary layer and / or secondary layer in a 50% crepe ie in a creping with a subsequent degree of crepe of 50%, a measured in the direction of layer thickness of 0.02 to 4 mm, preferably from 0.02 to 1, 4 mm or a thickness of substantially 0.04 mm or that the primary layer and / or secondary layer at a 30% creping, ie in a creping with a subsequent crepe degree of 30%, a thickness measured in the direction of layering of 0, 02 to 5 mm, preferably from 0.02 to 1, 8 mm or has a thickness of substantially 0.05 mm
- a proportion of the filling material is 50% to 80%, preferably 60% to 75% and particularly preferably between 65 and 73% of the filling layer. It is particularly preferable for the filler to comprise essentially 65% iron oxide and essentially a material based on 18% limestone.
- the term "essentially” in the context of the invention means deviations from the exact value by +/- 10%, preferably by +/- 5%, and / or deviations in the form of changes that are insignificant for the function

- the filling layer prefferably has a density of between 1.9 and 3.5 g / cm 3 , preferably between 2.2 and 3.0 g / cm 3 and particularly preferably between 2.4 and 2.8 g / cm 3 has.
- the filling layer is thicker than the primary layer and / or secondary layer. It is particularly preferred that, seen in the layering direction, the filling layer is 1 to 150 times, preferably 15 to 80 times and particularly preferably 20 to 40 times thicker than the primary layer and / or secondary layer, in particular as a sum of a thickness of the primary layer and the secondary layer.
- the thicknesses of the primary layer and the secondary layer are those prior to their creping. Furthermore, it is conceivable that the primary layer is thicker than the secondary layer. As a result, in the mounted state of the cover element, the primary layer facing an environment can advantageously be made weather-resistant and stable with respect to external influences.
- the layer thickness of the filling layer preferably has a value between 1 and 5 mm, preferably between 2 and 4 and particularly preferably between 2.2 and 3.2 mm, in particular if the density has a value of 2.6 kg / m.
- the thickness of the primary layer and the thickness of the secondary layer are each substantially 0.05 mm, and the thickness of the filler layer is substantially 2.2 or 3.2 mm.
