  • An insulation holder of the type mentioned, as in the DE 101 14 929 A1 serves as a fixture for attachment of insulating or insulating panels or mats to a supporting substrate and in particular to a wall or a ceiling of a building.
  • Corresponding insulation panels serve the heat and sound insulation of a building and are usually on the outside of an already existing building attached.
  • the insulation panels are pre-positioned and then a hole is made from the outside to the building wall or ceiling through which an insulation holder of the type mentioned is inserted.
  • the insulation holder has at its front end a dowel part with deforming projections that can clamp in the hole in the building wall or ceiling.
