The invention relates to a case for in particular facade-flush arrangement of a window or of a door on a wall cutout of a multi-layer external wall, which is characterised by a self-contained hollow case frame with an essentially plane rear wall on its outside, a front wall and two side walls, the clear internal dimensions of which are essentially the same as the corresponding internal dimensions of the respective wall cutout, in the cavity of which heat-insulating material is arranged and from the outer side wall of which a fastening flange extends outwards (Fig. 3). <IMAGE>
