Abstract: A doorframe fastening for a folding door comprises a doorframe profiled section (1), which has a securing limb (2) and a door leaf suspension (3). The doorframe fastening reliably withstands high weight loads and reduces noise emission but still allows a long-term use while avoiding cold bridges and damage from corrosion. An inner support limb (7) protrudes from the securing limb (2), said inner support limb being connected to an outer support limb (9) via a thermally insulating separating web (8), and the door leaf suspension (3) is supported both on the inner (7) as well as on the outer support limb (9).
