Abstract: The flashing component comprises a rigid flashing frame arrangeable against outer side faces of the main frame component and foldable resilient side flashing members, which can be folded to allow packing of the flashing component together with the window and main frame components into a single unit comprising all components needed for installation of the roof window assembly.

Abstract: The roof window assembly comprises a main frame component and a window component including a glazing element. In order to reduce the influx of light an external screening accessory is provided. The screening accessory comprises an elongate housing extending in parallel with the top and bottom members of the frame and from which a screening member is retractable by movement parallel to the side members of the frame. An end member connected with a free end of the screening member extends throughout the width of the window frame and includes engaging means at either end of the end member for engagement with a transverse inwards recess in the outer side of each side member of the window frame.

Abstract: A roof window assembly is composed of a window component, a main frame component and, optionally, an integrated flashing component. The window component may be used independently and without modifications for a roof window installation employing a curb-frame. The window component features a novel design with an glazing element fitted in a profiled sheet metal frame, which can be made from a single continuous sheet metal profile bent into a polygonal frame shape with corner junctions. In both fixed and ventilating versions of the roof window assembly identical connecting members into open mutual engagement at the top side of the window and main frame components provides for easy mounting and dismounting of the window component with respect to the main frame component.

Abstract: The window frame structure of the roof window is secured to the main frame structure within a predetermined range of the opening angle by means of a securing device comprising at least one torsion member. The torsion member is torsionally biased in the opening direction of the window and includes engagement means at a distance from the pivot axis for engagement with corresponding engagement means on the window frame structure. The securing device is automatically activated and deactivated during mounting and dismounting of the window frame from the main frame.

Abstract: A skylight window assembly comprises a curb frame having top edges for supporting a skylight window with glazing supported in a frame structure. Inside the curb frame an inner frame structure is arranged in floating suspension with respect to the curb frame to provide engaging means for panel members of an underlying shaft through the roof structure and at the same time to prepare for arrangement of an accessory like a screening device in connection with the window.
