<p>The invention relates to an insulating frame (1) for insulating a roof window (19). The frame comprises a plurality of insulating frame pieces (2a,2b,3,4), each of which having an inner side surface facing an opening surrounded by the frame, a bottom surface and at least one outer side surface facing away from the opening. At least one of the insulating frame pieces comprises a lower section (7) and an upper section (8), where the upper section has a first side facing the opening and a second side (9) facing away from the opening, a bottom portion of the upper section having a predetermined maximum width. The width between the first side and the second side of the upper section decreases from said maximum width in the height direction such that the second side forms a predetermined angle other than perpendicular with the bottom portion. Preferably, the upper section is substantially wedge shaped with an apex angle of 20-45 degrees. The height of the first side is such that a relatively large portion of the window frame piece (20) is overlapped by the upper section of the insulating frame piece in the mounted state.</p> |
