DETAILED DESCRIPTION
[0060] According to the invention, the object is to provide a building envelope 100, as shown in FIG. 12, with a bird protection effect. Here, the building envelope 100 shown in FIG. 12 has a partially-glazed faade with four faade elements 110 which have either already been provided with a film product 10 according to the invention during the production of the main faade body 112 or are subsequently provided with a film product 10 according to the present invention by affixing this to the individual faade elements 110 as transparent sections.
[0061] FIG. 1 shows a particularly simple possibility of a bird protection function, which does not however limit the invention. To illustrate the function, FIG. 1 shows the UV range UV, i.e. the perception as experienced by a bird. Here, several strip-formed UV bird protection sections 30 are integrated into a film body 20 which provides the film product 10. The bird protection effect is formed by a bird protection position BPP of the individual protection sections 30, so that here the bird protection position BPP forms the direction of extension, represented by the vertical double arrow, and the gap width between adjacent UV bird protection sections 30, represented here by the horizontal double arrow. An installation marking 40 is shown in the upper right corner of the film product 10. This contains an orientation section 42, which in this case represents an arrow-shaped information section 44. It is thus shown that the arrow pointing upwards shows in which direction the bird protection position BPP contains the individual UV bird protection sections 30 in an aligned manner. This provides an information display, which also represents information for the installer in the VIS range, as shown in FIG. 2. As FIG. 2 shows, the individual UV bird protection sections 30 are not recognisable in the VIS range. Simply for the sake of clarity, they are shown here schematically with dashed lines, whereas for the installer the film body 20 appears as a uniform and undivided surface. In the VIS range, they can only recognise the installation marking 40, so that they now know in which orientation the UV bird protection sections 30 lie in front of him, although they cannot see them.
[0062] FIG. 3 shows a further development of such a film product 10. Since film products 10 of this type are often transported and made available for installation rolled up on rolls, a repetitive application of an identically repeating installation marking 40 takes place here. These are all designed with an arrow-shaped information section as orientation section 42, as explained with reference to FIGS. 1 and 2.
[0063] FIG. 4 shows another variant which represents the installation marking 40 substantially across the film body 20 in the form of a watermark. The orientation section 42 is here again provided as an arrow with an information section 44 which points to the top right and thus again clearly correlates the desired installation position with the bird protection position BPP. Such a watermark is in particular designed in such a way that the effect in the VIS range is designed for a temporary fading period, so that, for example by using UV unstable dyes in the installation marking, this fades over time through exposure to sunlight after being applied to a building envelope 100 and thus loses visibility over time.
[0064] FIG. 5 shows another embodiment of the installation marking 40. The orientation section 42 is provided here with an origin section 46, represented schematically here as a circular logo. Here, there is no information section 44; rather, the information is encoded in that the installation marking 40 should always be arranged at the top left of the film body 20. Here, the bird protection position BPP is indicated in an indirect way, so to speak.
[0065] FIG. 6 shows a continuous design of the orientation section 42 of the installation marking 40. This correlates in particular with an additional indication, namely the indication of a trimming allowance TA, which will be explained later.
[0066] The functional principle for installation is briefly explained with reference to FIGS. 7 to 10. This can clearly be seen in particular if, in the case of wide faade elements 110, two or more film products 10 are to be arranged abutting each other. FIG. 7 shows the correct arrangement of the two adjacent film bodies 20 in the VIS range and FIG. 8 shows the same situation in the UV range. As can clearly be seen here, the right-hand film product 10, as a repeat pattern, seamlessly continues the strip-formed pattern of the UV bird protection sections 30 of the left-hand film product 10. This was ensured because the installer was able to take this desired relative correlation into account in the arrangement in the VIS range through the installation markings 40 of both film products 10.
[0067] FIGS. 9 and 10 show the same situation, but with an incorrect and thus false relative alignment of the film products 10 in relation to each other. This would be the case if, as shown in the UV range of FIG. 10, the right-hand film product 10 were incorrectly applied, rotated by 180. This leads to a defective formation of the pattern repeat between the two film products 10 and to the formation of a gap width which is twice as wide, and thus undesirable, between the adjacent UV bird protection sections 30 at the join. This could lead to this larger gap width being perceived by birds as a fly-through path, so that the bird protection function is significantly minimised by this incorrect relative positioning. However, this is avoided, or the risk of such a misalignment is reduced, since, in the VIS range, as shown in FIG. 9, this misalignment is also visible to the installer due to the relative positioning of the two installation markings 40, so that they will recognise this installation as being incorrect and avoid it.
[0068] FIG. 11 shows a detail of the abutting arrangement as explained in FIGS. 7 to 10. In order to enable a gap-free arrangement of film products 10 next to each other, in this case an overlap OL is formed during installation which is then trimmed off, preferably after the adhesive connection to the building envelope 100 has been completed. This is referred to here as the trimming allowance TA and is taken into account in particular in forming the geometric correlation of the UV bird protection sections 30 and thus in the formation of the bird protection position BPP. Another advantage of the embodiment of FIG. 11 is that the installation marking 40 is integrated here into the trimming allowance TA, so that, by trimming off the overlap OL as the last installation step, the installation marking 40 is removed from the film product 10 as part of the trimming allowance TA. Thus, after this last step, an installation marking 40 is no longer included, and is no longer included, as an impairment, in the film body 20.
[0069] FIG. 12 shows the finished formation, in which the facade elements 110 with their main facade bodies contain the film products 10 and thus the building or building envelope 100 is provided with the desired bird protection function.
[0070] The above explanation of the embodiments describes the present invention exclusively in the context of examples. Of course, individual features of the embodiments can be freely combined with each other, where technically expedient, without departing from the scope of the present invention.
