DETAILED DESCRIPTION OF THE INVENTION

(7) In FIG. 1, a window mounting collar (1) is shown before installation on a building faade. The mounting collar (1) comprises two side boards (2), an upper cross board (3) and a lower cross board (4), each having an inside face (2a, 3a, 4a) and an outside face (2b, 3b, 4b), wherein each side board (2) is joined orthogonally to the upper and lower cross boards (3, 4). The mounting collar has a first open end (5), which, when installed, faces the exterior face of the building faade. The second open end (6) of the mounting collar (1) receives a window frame, which can be installed either before the mounting collar is affixed to the building faade or after the mounting collar has been affixed to the building faade.

(8) In the embodiment shown, the two side boards (2), the upper cross board (3) and the lower cross board (4) are each formed from three layers of man-made vitreous fibre boards, each layer comprising man-made vitreous fibres and binder.

(9) Attached to the mounting collar (1), on its outside faces (2b, 3b, 4b), are brackets (7). In the embodiment shown, the brackets (7) are L-shaped brackets, which are positioned on the outside faces of the mounting collar adjacent to its first open end (5).

(10) FIG. 2 shows the mounting collar (1) in place on a building faade (8), as part of a complete window mounting system. Brackets (7) affix the mounting collar (1) to the exterior face of the building faade (8). A window frame (9) is mounted in the mounting collar such that there is a separation (d) (shown in FIG. 3) of at least 10 mm between the window frame (9) and the plane of the exterior face of the building faade (8). The window frame (9) surrounds a window sash (10) and window panes (11). External wall insulation (12) (not shown on one side of the mounting collar) is positioned around the outside of the mounting collar (1) and affixed to the building faade (8). The external wall insulation (12) has the same depth as the mounting collar (1), so the window frame (9) is arranged to be flush with the outer surface of the external wall insulation (12).

(11) FIG. 3 shows a section through the system of FIG. 2, viewed from above. The side boards (2) of the mounting collar (1) are affixed to the exterior face (13) of the building faade (8). The side boards (2) extend perpendicularly outwards from the building faade (8). L-shaped brackets (7) have two perpendicular arms, one of which is attached to an outside face (2b) of the mounting collar (1), the other of which is attached to the exterior face (13) of the building faade (8). The separation (d) between the window frame (9) and the plane of the exterior face (13) of the faade allows the mounting collar (1) to be fitted when an existing window is still present in the window opening (14). External wall insulation (12) is present on either side of the mounting frame (1). The mounting collar (1) extends away from the building faade (8) by the same distance as the depth of the external wall insulation (12). Means for attaching the window frame (9) to the mounting collar (1) are not shown, but could, for example, be screws passing through the window frame (9) and into the mounting collar (1).

(12) FIG. 4 shows a corner bracket assembly according to an embodiment of the invention. Bracket part (15) has base arms (16) in the form of plates and second arm (17), which comprises two plates (17a, 17b) that are substantially perpendicular to each other and are joined at one edge. The second arm (17) of the bracket part (15) extends away from the exterior face of the building faade along two of the outside faces (2b, 3b) of the mounting collar (1). The two base arms (16) of the bracket part (15) each have holes (18) for accepting screws.

(13) Holding part (19) has an attachment arm (20) and a holding arm in the form of holding plate (21). The attachment arm (20) is in the form of two substantially orthogonal plates (20a, 20b), attached to each other at one edge, and each attached to the holding plate (21) at one end. The holding plate (21) is L-shaped to match the shape of the corner of the mounting collar (1) and has two flanges (22) that are perpendicular to each other and perpendicular to the holding plate (21). The flanges (22) extend from edges of the holding plate (21) opposite to the edges attached to the plates (20a, 20b) of the attachment arm (20). The flanges (22) lie against two of adjoining inside faces (2a, 3a) of the mounting collar (1).

(14) FIG. 5 shows a mounting clip system according to the invention. The mounting clip (23) has a base plate (24) and first and second side plates (25, 26) extending from opposite ends of the base plate (24). The clip (23) is shown arranged on the mounting collar (1) at its second end (6) such that the first side plate (25) abuts an inside face (2a) of the mounting collar (1) and the second side plate (26) abuts an outside face (2b) of the mounting collar (1). The first side plate (25) of the window mounting clip (23) is shaped as a wedge, having a thickness at its end furthest from the base plate (24) that is greater than the thickness of the first side plate (25) of the window mounting clip (23) at its end that is adjoined to the base plate (24).

(15) In the embodiment shown, the mounting clip (23) forms one part of a clip system. The clip system comprises the mounting clip (23) and a separate plate (27). The face of the first side plate (25) of the mounting clip that faces away from the second side plate has ridges (28). The peaks of the ridges are substantially parallel to the base plate (24) of the clip. The clip system also comprises a separate plate (27) having ridges (29) on one of its faces that are adapted to cooperate with the ridges (28) on the first side plate (25) of the mounting clip. A window frame (not shown) can be set in place by positioning the window frame in the mounting collar (1) and then pushing the separate plates (27) in between the window frame and the mounting clip (23). The frame is then fixed in place with screws.
