(c) inserting said longitudinal flange of each of said plurality of rigid mounting rails into the corresponding exterior-facing accessory groove of the header, left jamb, right jamb, and sill of said window frame;
(d) fixedly mounting a security screen to said exterior-facing surface of at least one of said plurality of mounting rails using an attachment means wherein said attachment means comprises screws or bolts.
2 . The method of claim 1 wherein at least one of said two substantially parallel sides of said longitudinal flange configured to fit within and be inserted into said exterior-facing accessory groove of the header, left jamb, right jamb, and sill of the window frame further comprises a plurality of longitudinal ridges.
3 . The method of claim 1 further comprising the step of applying of a bead of construction adhesive to said longitudinal flange prior to inserting said longitudinal flange of each of said plurality of mounting rails into the corresponding exterior-facing accessory groove of the header, left jamb, right jamb, and sill of said window frame.
4 . The method of claim 1 wherein said security screen comprises a subframe, and a main frame pivotably attached to said subframe.
5 . The method of claim 4 wherein said subframe further comprises a mounting flange at its outer perimeter, and said attachment means comprises screws attaching said subframe to said exterior-facing surface of said at least one of said plurality of rigid mounting rails through said mounting flange.
6 . The method of claim 4 wherein said exterior-facing surface of at least one of said plurality of rigid mounting rails further comprises at least one threaded hole, said subframe further comprises a mounting flange at its outer perimeter, said mounting flange comprises at least one mounting hole aligned with said at least one threaded hole in said exterior-facing surface of at least one of said plurality of rigid mounting rails, and said attachment means comprises at least one bolt attaching said subframe to said exterior-facing surface of said at least one of said plurality of rigid mounting rails through said mounting flange.
7 . The method of claim 1 , wherein said security screen comprises at least two screen panels, a first screen panel of which is fixedly attached to said exterior-facing surface of at least two of said plurality of rigid mounting rails, and a second screen panel of which is attached to said first screen panel by a pivotable mounting means.
8 . The method of claim 1 , wherein said security screen is attached to one of said plurality of rigid mounting rails by a pivotable mounting means.
9 . A method for mounting a security screen to a window frame, wherein said window frame has frame members consisting of a header, a left jamb, a right jamb, and a sill, and an outer perimeter comprising an exterior-facing accessory groove; the method comprising:
(a) measuring the length of said exterior-facing accessory groove of the header, left jamb, right jamb, and sill of said window frame;
(b) sizing each of a plurality of rigid mounting rails to fit the measured length of said exterior-facing accessory groove of the header, left jamb, right jamb, and sill of the window frame, each of said plurality of rigid mounting rails having an exterior-facing surface and a longitudinal flange perpendicular thereto, said longitudinal flange comprising two substantially parallel sides, and configured to fit within and be inserted into said exterior-facing accessory groove of the header, left jamb, right jamb, and sill of said window frame;
(c) inserting said longitudinal flange of each of said plurality of rigid mounting rails into the corresponding exterior-facing accessory groove of the header, left jamb, right jamb, and sill of said window frame;
(d) fixedly mounting a security screen to said exterior-facing surface of at least one of said plurality of mounting rails using an attachment means, wherein said security screen comprises a subframe, and a main frame pivotably attached to said subframe, said subframe comprising a mounting flange at its outer perimeter, and said attachment means fixedly mounting said subframe to said exterior-facing surface of said at least one of said plurality of rigid mounting rails through said mounting flange.
10 . The method of claim 9 further comprising the step of applying of a bead of construction adhesive to said longitudinal flange prior to inserting said longitudinal flange of each of said plurality of mounting rails into the corresponding exterior-facing accessory groove of the header, left jamb, right jamb, and sill of said window frame.
11 . The method of claim 9 wherein at least one of said two substantially parallel sides of said longitudinal flange further comprises a plurality of longitudinal ridges.
12 . The method of claim 9 , wherein said security screen comprises at least two screen panels, a first screen panel of which is fixedly attached to said exterior-facing surface of at least two of said plurality of rigid mounting rails, and a second screen panel of which is attached to said first screen panel by a pivotable mounting means.
13 . The method of claim 9 , wherein said security screen is fixedly attached to one of said plurality of rigid mounting rails by a pivotable mounting means.
14 . A method for mounting a security screen to a window frame, wherein said window frame has frame members consisting of a header, a left jamb, a right jamb, and a sill, and an outer perimeter comprising an exterior-facing accessory groove; the method comprising:
(a) measuring the length of said exterior-facing accessory groove of the header, left jamb, right jamb, and sill of said window frame;
(b) sizing each of a plurality of rigid mounting rails to fit the measured length of said exterior-facing accessory groove of the header, left jamb, right jamb, and sill of the window frame, each of said plurality of rigid mounting rails having an exterior-facing surface and a longitudinal flange perpendicular thereto, said longitudinal flange comprising two substantially parallel sides, and configured to fit within and be inserted into said exterior-facing accessory groove of the header, left jamb, right jamb, and sill of said window frame;
(c) applying of a bead of construction adhesive to said longitudinal flange of each of said plurality of rigid mounting rails;
(d) inserting said longitudinal flange of each of said plurality of rigid mounting rails into the corresponding exterior-facing accessory groove of the header, left jamb, right jamb, and sill of said window frame;
(e) fixedly mounting a security screen to said exterior-facing surface of at least one of said plurality of mounting rails using an attachment means.
15 . The method of claim 14 , wherein at least one of said two substantially parallel sides of said longitudinal flange configured to fit within and be inserted into said exterior-facing accessory groove of the header, left jamb, right jamb, and sill of the window frame further comprises a plurality of longitudinal ridges.
