An insulating material for insulating a structural element in a vehicle including a support element with a first surface and a second surface, and an expandable material which is arranged on the support element. The expandable material is arranged here on a first sub-region of the first surface of the support element, and a second sub-region of the first surface is free from expandable material. The first sub-region is configured here in such a manner that the first surface of the support element is completely covered with expanded material after expansion of the expandable material.

Insulating element

A system of a reinforced structural element of motor vehicle include: structural element includes a first and second sheet, wherein the sheets are connected to one another at first and second joining points, wherein the sheets form elongate cavity in region between the joining points, and wherein second sheet has, in region between first and second joining points, a bulge with first leg arranged at first joining point and with second leg arranged at second joining point; a reinforcing element includes a first and second side walls connecting the wall arranged in cavity of structural element; and adhesive bonding reinforcing element to structural element; wherein first side wall of reinforcing element arranging the first joining point and second side wall of reinforcing element arranging the second leg of second sheet so larger portions of force acting on first joining point of reinforcing element transferring, to second leg of second sheet.
