2. The thermal and/or acoustic insulation system according to claim 1 ,
wherein
the insulation element has at least two layers of different bulk density whereby the layer with the higher bulk density is in contact with the lining element.
3. The thermal and/or acoustic insulation system according to claim 1 ,
wherein

5. The thermal and/or acoustic insulation system according to claim 1 ,
wherein
a wind uplift resistance of at least 3.500 N/m 2 .
6. The thermal and/or acoustic insulation system according to claim 2 ,
wherein
the bulk density of the insulation element layer being in contact with the lining element is 40% up to 100% higher than the bulk density of the layer being oriented opposite the lining element.
7. The thermal and/or acoustic insulation system according to claim 1 ,
wherein
a second major surface of the insulation element being oriented parallel to the major surface of the insulation element is free of protrusions and cavities thereby being planar.
8. A method for producing a thermal and/or acoustic insulation system as waterproofing for a flat or flat inclined outside surface of a building consisting of at least one insulation element made of mineral wool and having a major surface, and a lining element consisting of at least a first layer made of lining material and a second layer made of a glue activatable by heat and oriented to the major surface of the insulation element, whereby protrusions and cavities are removed from the major surface of the insulation element so that the major surface is planar, whereby the insulation element is placed on the outside surface of the building with the planar surface being oriented distant from the outside surface of the building, whereby the lining element is placed on the planar surface of the insulation element with its layer of glue being at least partly in contact with the major surface of the insulation element and whereby the glue is heated up to its melting temperature.
9. The method according to claim 8 ,
wherein
the lining element is placed at a roll on top of the planar surface of the insulation element whereby an upper area of the roll is heated up to the melting temperature and whereby the roll is then scrolled until the heated upper area gets into contact with the planar surface of the insulation element.
10. The method according to claim 8 ,
wherein
any protrusions of the major surface of the insulation element are removed by sawing and/or grinding followed by removing the fibers not being bound to the insulation element.
11. The method according to claim 8 ,
wherein
the lining element is connected to the insulation element on at least 70% of the planar surface area of the insulation element.
12. The method according to claim 8 ,
wherein
the lining element is connected to an insulation element having at least two layers of different bulk densities whereby the layer with the higher bulk density is in contact with the lining element.
