An improved security window cover is provided having a peripheral frame structure and a security shielding door or cover hingedly attached to the frame. The frame has at least two walls intended to conform to the interior building wall adjacent the window and at least two other walls intended to ultimately conform to the shape, contour and dimensions of the inner circumferential edge of the wall opening in which the window is installed. The inner circumferential walls of the frame have a degree of flexibility, thereby allowing the installer to quickly and easily bend or shape the inner circumferential wall to conform to the inner circumferential edge of the wall opening in which the window is installed. The shielding door may have a ridge medial and parallel to the edges of the door and on the side thereof facing the outside of the building. The ridge serves to strengthen the door, protect the means employed to fasten the frame to the building against tampering from the outside and act as a guide and support for insulation for energy conservation purposes.
