The frame for mounting to a roof upstand or curb comprises a first frame portion 14 for supporting an aperture cover, such as a pane of glass, attached to a roof upstand by a securing affixing fastening arrangement. A second frame portion 36 is attached to the first frame portion and is covered to prevent, inhibit , limit, conceal, access to the fastening arrangement. The frame may also include a third resilient portion 50 designed to move or deform in the event of an applied force to the frame. The frame may include a predefined weakness such that the second portion inhibits access to the fastening arrangement after there has been a failure at the predefined weakness. The frame portion may be configured to support a planar aperture covering or a three dimensional covering. The frame portions may be made from several interengaging portions which can be separated or they may be integral to each other. |
