Method for glazing a door, the door comprising a first outer layer comprising a first outer side and a first inner side, a second outer layer comprising a second outer side and a second inner side and an insulating layer arranged between the first inner side and the second inner side, the method comprising the steps: - to place a unit of glass in an existing through opening in a door; - to place a first strip to abut against the unit of glass and to abut against the door; - to attach the first strip against the door by means of an existing first flange of the first strip being arranged, by means of snap function, against the first inner side of the first outer layer between the unit of glass and the first outer layer, the first outer layer comprises a first edge defining the opening in the first outer layer, where the first edge comprises second protrusions, characterized in that the method further comprises the step: - to place the first flange on the first inner side of the first outer layer at least against the second protrusions, wherein the first flange is snapped into place against the first inner side by means of the first strip and/or parts of the first flange elastically giving way to the pressure that arises between the first flange and the first outer side of the first outer layer as the first strip by means of pressure is placed in the opening, and/or the first flange is snapped into place against the first inner side by means of the second protrusions elastically giving way to the pressure that arises between the first flange and the first outer side of the first outer layer as the strip by means of pressure is placed in the opening. - to place a unit of glass in an existing through opening in a door; - to place a first strip to abut against the unit of glass and to abut against the door; - to attach the first strip against the door by means of an existing first flange of the first strip being arranged, by means of snap function, against the first inner side of the first outer layer between the unit of glass and the first outer layer, the first outer layer comprises a first edge defining the opening in the first outer layer, where the first edge comprises second protrusions, characterized in that the method further comprises the step: - to place the first flange on the first inner side of the first outer layer at least against the second protrusions, wherein the first flange is snapped into place against the first inner side by means of the first strip and/or parts of the first flange elastically giving way to the pressure that arises between the first flange and the first outer side of the first outer layer as the first strip by means of pressure is placed in the opening, and/or the first flange is snapped into place against the first inner side by means of the second protrusions elastically giving way to the pressure that arises between the first flange and the first outer side of the first outer layer as the strip by means of pressure is placed in the opening. - to place the first flange on the first inner side of the first outer layer at least against the second protrusions, wherein the first flange is snapped into place against the first inner side by means of the first strip and/or parts of the first flange elastically giving way to the pressure that arises between the first flange and the first outer side of the first outer layer as the first strip by means of pressure is placed in the opening, and/or the first flange is snapped into place against the first inner side by means of the second protrusions elastically giving way to the pressure that arises between the first flange and the first outer side of the first outer layer as the strip by means of pressure is placed in the opening.
