Abstract
A roof window frame comprising at least four elongate frame members joined about their ends forming a quadrangular shaped frame defining a central aperture. Each frame member has a main aperture facing surface and a main roof facing surface, the two main surfaces facing in opposite directions with the thickness of the frame member being defined between these main surfaces. The frame members have a reduced thickness base member and an integral insulation member carried on the main roof facing surface of the reduced thickness base member so that the overall size and shape of the reduced thickness base member and the integral insulation member is the same as an unaltered frame member for the same specification of roof window.
