FASTENER, METHOD OF FASTENING INSULATION BY MEANS OF THE FASTENER AND A FASTENING SYSTEM
The present invention relates to a fastener, a method of fastening insulation (2) to the frame (3) by means of the fastener (1) and a fastening system. In the method, a screw (9) and an installation tool (8) are in-stalled in a hole (6) at the center of the fastener (1), the external shape of the installation tool being arranged to correspond, at least along a part of the height of the installation tool (8), to the shape of the inner space (6) along at least a part of the height of the inner space (6). The screw (9) is rotated by means of the installation tool (8), whereby the fastener (1) and the screw (9) rotate simultaneously, boring into the insulation (2), and as the screw (9) rotates, it pulls the lower part of the fastener (1) to contact the frame (3).
