<p>The invention relates to a flashing cover with at least one internal corner, apt to seal constructions installed within a roof of the building, in a form of a thin substantially flat sheet of metal provided at its periphery with at least one polygonal cutout. At least two sides of this cutout are one-sidedly slanted forming the walls of the cover joined together into a uniform flange (11) connected with the cover main part (12). Among these two adjacent walls of the flange, at least one wall is a wall (13) non-perpendicular relative to the cover main part (12), At a corner of the flange (11), a radius of a curvature of the flange is many times smaller than a radius of a curvature of the base of the flange. A method of manufacturing a flashing cover according to the present invention comprises the first step of forming in a sheet of metal an embossed area having a bottom of a shape and dimensions corresponding to given desired shape and dimensions of the final produced cover cutout, and subsequently realized the second step of cutting out the bottom of the embossed area from the sheet of metal thus forming a cutout in the cover.</p> |
