DETAILED DESCRIPTION

(12) Example embodiments will now be described more fully with reference to the accompanying drawings.

(13) FIG. 1 shows a first embodiment of a packing- and/or transport unit 1 comprising three layers of insulation elements 4 for flat roof insulation being arranged in one stack 2. The stack 2 is arranged on support means 3 being arranged under the stack 2 for resting on a support surface 6. In a preferred embodiment the stack 2 contains mineral wool lamellas as insulation elements 4, having a high compression strength and low point load resistance due to their mineral fiber orientation.

(14) Each insulation element 4 has four side faces of which one side face 7 is visible in FIG. 1 and a lower surface 8 and an upper surface 9 being connected to the side faces 7 which are arranged rectangular to each other. The lower surface 8 and the upper surface 9 are arranged spaced apart and non-parallel to each other, whereby the insulation elements 4 are arranged in layers forming the stack 2.

(15) The support means 3 comprise two carrying feet 10. The carrying feet 10 have different heights and provide therefore a leveling means ensuring that the top plane 15 (indicated by a dotted line) of the transport unit 1, which in this embodiment corresponds to the upper surface 9 of the top layer of the insulation elements 4, is arranged parallel to the support surface 6.

(16) From FIG. 1 it can be seen that the upper and the lower insulation element 4 of the stack 2 are directed in the same direction so that the ends of the insulation elements 4 having the bigger height are arranged at one side of the packing and/or transport unit whereas the middle layer of the insulation elements 4 is arranged in opposite direction so that the end with the bigger height of the middle layer of the insulation elements 4 is arranged at the side of the stack 2 where the ends of insulation elements 4 of the upper and lower layer with the smaller heights are arranged. Since the number of layers of insulation elements in the stack 2 is uneven (three layers in this embodiment) the upper and lower surfaces of the stack 2 are not parallel.

(17) Nevertheless, by using the leveling means in form of the carrying feet 10 of different heights the upper surface 9 of the stack 2 (and thereby the top plane 15 of the packing and/or transport unit 1) is arranged parallel to the support surface 6 so that a further stack 2 can be arranged on the upper surface 9 as it is shown in e.g. FIG. 6 which will be described later on.

(18) As already mentioned the insulation elements 4 are preferably lamellae made from mineral fibres which are bound with an organic binder. In the same way the carrying feet 10 are preferably made from mineral fibres bound with an organic binder so that the carrying feet 10 can be used for the insulation of the flat roof.

(19) FIG. 2 shows a second embodiment of a packing and/or transport unit 1 in a perspective view. It can be seen from FIG. 2 that the insulation elements 4 are again arranged in three layers with five insulation elements 4 side by side in each layer on an insulation board 5 being arranged on the carrying feet 10 being spaced apart to each other and running perpendicular to the lengthwise direction of the insulation elements 4.

(20) Furthermore, a second insulation board 5 is arranged as a covering on top of the uppermost layer of insulation elements. The size of both insulation boards 5 on top of the carrying feet 10 and on top of the top layers of the insulation elements 4 is equal to the length and the width of the insulation elements 4 in each layer, so that both insulation boards 5 cover the whole upper surface and the whole lower surface of the stack 2.

(21) Both insulation boards 5 stabilize the packing and/or transport unit 1 and protect the upper and lower surfaces of the insulation elements 4 against damages. Additionally, the insulation boards 5 are applicable as a point load pressure resistant layer on top of the insulation elements 4, when they have been applied to the roof.

(22) Furthermore, it can be seen from FIG. 2 that each carrying feet 10 consists of several stacked strips 11, which are preferably cut from an insulation board 5. The left carrying feet 10 consists of five insulation board strips 11 whereas the right carrying feet 10 consists of four insulation board strips 11. The insulation board strips 11 are preferably made from mineral fibres bound with an organic binder and which may have the same thickness as the insulation boards 5 so that the insulation strips 11 can be used together with the insulation boards 5 in the roof insulation.

(23) The insulation boards 5 have an even higher compression strength and a higher point load resistance than the insulation elements 4 so that they can be used as a pressure resistant top layer in a flat roof insulation.

(24) FIG. 3 shows the packing and/or transport unit 1 according to FIG. 2 in a side view.

(25) FIG. 6 shows two of the before-described packing and/or transport units 1 according to FIG. 2 arranged on top of each other, and it can be seen that due to the different heights of the carrying feet 10 the top plane 15 (corresponding to the top surface) of the packing and/or transport units are parallel with the support surface 6, so that stable stacking is ensured.

(26) A further embodiment of a packing and/or transport unit 1 can be seen from FIG. 4. This packing and/or transport unit 1 according to FIG. 4 differs from the embodiment according to the before-described FIGS. 1 to 3 in that both carrying feet 10 have the same height and that there is provided one insulation board 12 having different heights at opposite ends so that this insulation board 12 has a cross-section in form of approximately a triangle or a wedge. This insulation board 12 is used as the leveling means ensuring that the top plane 15 (corresponding to the upper surface 13 of the insulation board 5 being arranged on the top surface of the stack 2) is arranged parallel to the support surface 6.

(27) As can be seen from FIG. 4 the length of the insulation board 12 is shorter than the length of the insulation board 5 being arranged on top of the right carrying foot 10 and on the insulation board 12 being arranged on top of the left carrying foot 10.

(28) The insulation board 12 is made from mineral fibres bound with an organic binder. It can be used for the flat roof insulation.

(29) FIG. 5 shows a further embodiment of the packing and/or transport unit 1 which is very similar to the embodiment according to FIG. 4 and which differs from the embodiment of FIG. 4 in that the insulation board 12 has the same length as the insulation board 5 covering the lower surfaces of the insulation elements 4 being arranged as lowest layer of the stack 2. Instead of being arranged underneath the stack 2 the insulation board 12 could also be arranged between two layers of the insulation elements 4.

(30) FIGS. 7 to 9 show further embodiments of a packing and/or transport unit according to the invention. In these embodiments the leveling means comprises a strip 14 of pressure resistant material arranged somewhere in or on the stack 2 near to one end thereof. The strip 14 for the leveling means may be identical with the strips 11 used for the carrying feet 10 or it may be different in relation to material and dimensions. In FIG. 7 the strip 14 is arranged directly on top of a lower insulation board 5. In FIG. 8 the strip 14 is arranged between the second and third layers of insulation elements 4, and in FIG. 9 the strip 14 is arrange on top of the stack 2 of insulation elements 4. In FIGS. 7 and 8 the top plane 15 of the packing- and/or transport unit 1 corresponds to the upper surface of the stack 2. In FIG. 9 the top plane 15 is indicated by a dotted line that indicates an imaginary top surface of the packing- and/or transport unit 1 that allows stable stacking of two packing- and/or transport units 1.

(31) It is preferred that the whole packing and/or transport unit 1 is enveloped in a foil which protects the insulation elements 4, the insulation boards 5 as well as the support means 3 against water ingress and damages. The foil, which is not shown in the figures, surrounds the whole stack 2 and the support means 3.

(32) As mentioned the insulation elements and the insulation boards 5 as well as the carrying feet 10 can be made from any insulating material, but are preferably made from mineral fibers, preferably from stone wool which mineral fibers are bound with artificial resin.
