[0044] In the illustrated embodiment, the angles α1 , α2 , α3 forming the tops 114 , 214 , 314 are acute angles.

[0045] In the embodiment shown, the openings of the respective slit-shaped cavities 105, 205, 305 of the lateral intermediate waterproofing element 100, the first lateral longitudinal waterproofing element 200 and the second lateral longitudinal waterproofing element 300 are arranged at the respective first curved portions 108, 208, 308, and the bottoms 106, 206, 306 of the respective slit-shaped cavities 105, 205, 305 are provided by the respective second curved portions 109, 209, 309 and in the installed position, with reference to Figure 2 and Figure 3 , the longitudinal portion of the second bent portion 209 of the first lateral longitudinal waterproof element 200 is accommodated in the slit-shaped cavity 105 of the lateral intermediate waterproof element 100 at the upper longitudinal end 120 of the lateral intermediate waterproof element 100, and the longitudinal portion of the second bent portion 109 of the lateral intermediate waterproof element 100 is accommodated in the slit-shaped cavity 305 of the second lateral longitudinal waterproof element 300 at the lower longitudinal end 121 of the lateral intermediate waterproof element 100.

[0046] Reference Figure 6 and Figure 7 , it is noted that, as seen in the figures, the respective dimensions or widths of the respective cavities 105, 205 and 305 in the vertical direction should be sufficient to accommodate the respective intended bends, and further, the cavities thus joined should have an opening width sufficient to accommodate the elements formed by the sheet material, as described below.

[0047] It is also noted that due to the Z-shape, in addition to the cavities 105, 205 and 305 opening on the inner portions 102a, 202a, 302a of the second legs 102, 202, 302, respectively, second cavities parallel to the first cavities 105, 205 and 305 open at the respective second curved portions 109, 209 and 309. As will be envisioned by a person skilled in the art, some of these second cavities will also accommodate curved portions, however, for example, the second cavity of the second lateral longitudinal waterproofing element 300 will not receive curved portions and may be as Figure 7 Folded as seen in .

[0048] It should be noted that the longitudinal portion 110 of the lateral intermediate flashing element 100 may be provided as a single bent piece of sheet material, or may be provided by more bent pieces of sheet material, connected for example by joints 132, for example.
