1. A method of fastening an edge structure to a construction element, the method comprising the steps of: providing the construction element, being a planar structure with with two cover regions and a middle region between the cover regions, wherein a material density in the cover regions is larger than in the middle region;providing the edge structure being continuously extended, the edge structure comprising contact surfaces with a thermoplastic material shaped to lie against the cover regions in an outer surface of the construction element, and, opposite the contact surfaces, a coupling-in surface for coupling energy into the edge structure;coupling energy into the edge structure and pressing the contact surfaces against the cover regions until at least a portion of the thermoplastic material is liquefied and pressed into the cover regions; andrepeating or continuing the steps of coupling and pressing until the edge structure is attached to the lightweight building element at a plurality of discrete locations or over an extended region along an edge of the construction element. 2. The method according to claim 1, wherein the step of coupling energy into the edge structure comprises coupling mechanical vibration into the edge structure. 3. The method according to claim 1, wherein continuing the steps of coupling and pressing comprises moving along the edge a roller capable of coupling energy into the edge structure through the coupling-in surface. 4. The method according to claim 1, wherein continuing the steps of coupling and pressing comprises moving along the edge a flat tool capable of coupling energy into the edge structure through the coupling-in surface. 5. The method according to claim 1, wherein repeating the steps of coupling and pressing comprises repeatedly pressing a tool capable of of coupling energy into the edge structure through the coupling-in surface against regions of the edge. 6. The method according to claim 5, wherein the regions of the edge are overlapping. 7. The method according to claim 1, and causing the edge structure to not be pressed against the middle region during the step of coupling and pressing or pressed against the middle region by a substantially smaller pressing force than against the cover regions. 8. The method according to claim 7, wherein the middle region comprises a deformable material, wherein the method comprises placing the edge structure relative to the construction element prior to the step of coupling and pressing, and wherein the middle region is caused to be deformed by the step of placing. 9. The method according to claim 7, wherein the middle region is indented along the outer surface of the construction element. 10. The method according to claim 7, wherein the edge structure is indented opposite the middle region. 11. The method according to claim 7, wherein the step of coupling energy into the edge structure comprises coupling mechanical vibration into the edge structure by a sonotrode, and wherein the sonotrode is indented along the middle region. 12. The method according to claim 7, and causing the edge structure to be at a distance from the middle region at least during an initial stage of the step of coupling energy into the edge structure and pressing the contact surfaces against the cover regions. 13. The method according to claim 1, wherein the construction element is sandwich element with the cover regions being constituted by cover layers of a first material composition and the middle region being constituted by a filling layer of a second material composition. 14. The method according to claim 13, wherein the construction element is a board element with a material composition with a density continuously varying from a first one of the cover regions to the middle region and from the middle region to a second one of the cover regions. 15. The method according to claim 1, wherein the edge structure is free of elements protruding beyond the cover regions. 16. A continuous edge structure for a construction element, wherein: the construction element is a planar structure with two cover regions and a middle region between the cover regions, wherein a material density in the cover regions is larger than in the middle region;wherein the edge structure comprises contact surfaces with a thermoplastic material shaped to lie against the cover regions in an outer surface of the lightweight building element and further comprises, opposite the contact surfaces, a coupling-in surface for coupling mechanical vibration energy into the edge structure by a sonotrode;the edge structure is shaped so that at least a portion of the thermoplastic material is liquefied and pressed into the cover regions when energy is coupled into the edge structure while the contact surfaces are pressed against the cover regions by the sonotrode pressing against the coupling-in surface while subject to mechanical vibrations; and,the edge structure is continuously extended to run along an edge of the construction element. 17. The edge structure according to claim 16 being indented opposite the middle region. 18. The edge structure according to claim 17, wherein the contact surfaces comprise energy directing structures. 19. The edge structure according to claim 16 being an endless edge structure configured to be extend continuously along the outer surface and to be cut to size adapted to an extension of the construction element.
