Claim:
1. A corner bracket for assembly of two boards of a window mounting collar into a collar corner and for affixing said window mounting collar to an exterior face of a building façade so as to surround a window opening, said corner bracket comprising; two holding plates and two base arms adapted for extending in planes parallel with and having back surfaces abutting the exterior face of the building façade in an affixed position of the collar, the two base arms each being adapted for receiving a fixation member for insertion therethrough and into the building façade such as to fixate the collar to the façade; a flange arm comprising two flanges adapted to extend away from said exterior face in the affixed position of the collar, each flange having a proximal end configured to be proximal and a distal end configured to be distal to the exterior face in the affixed position of the collar, each flange further having an attaching edge extending from the proximal end to the distal end, the attaching edges of the flanges being attached to each other along at least a part of the attaching edges, the flanges extending with an angle between them such as to form a flange corner at said attaching edges, the flange corner being adapted to be positioned in an inner corner formed between the two boards in the affixed position of the collar; two abutment plates adapted to extend away from said exterior face in the affixed position of the collar, each abutment plate having a proximal end configured to be proximal and a distal end configured to be distal to the exterior face in the affixed position of the collar, each abutment plate being adapted to abut a respective outer surface of the two boards in the affixed position of the collar; and each abutment plate being positioned at a mutual distance from and in parallel with an associated said flange, each abutment plate being connected to the associated said flange via an associated said holding plate; so as to be able to hold said boards together to form said window collar corner, each board being received between a respective flange and its associated abutment plate.
