A fastening device (100,200,300,400) for fastening a layer of insulating material (10,20,30,40) to a support (11,21,31,41), the device comprising a first tubular (110,210,310,410) member with a first end for penetrating into the insulating material and for being fastened to the support by means of a screw received in the tubular member, and a second tubular (120,220,320,420) member for penetrating into the insulating material (10,20,30,40) and with a second end opposite the first end, and a flange (122,222,322,422) at the second end for abutting a surface of the insulating material (10,20,30,40), wherein the first tubular member and the second tubular member are movable relative to each other in an axial direction with an adjustable upper limit of their total length. Such a fastening device (100,200,300,400) allows adjustment to a range of thicknesses of the layer of insulating material (10,20,30,40), and the device can be manually adjusted according to actual need e.g. on the location of use. |
