ABSTRACT OF THE DISCLOSURE A covering frame for roof windows, doors, facade linings or auxiliary materials, the covering including a lead apron forming a water-tight transition. The lead apron has an aluminum layer glued to the top of the lead layer. The aluminum layer protects the lead layer to reduce the likelihood of cracks arising in the lead apron, as well as prevents the leaching of the lead due to weathering. At the same time, the aluminum layer provides for a permanent, decorative appearance of the lead apron. Further protection is available against atmospheric corrosion by applying a coat of paint to the aluminum layer. Preferably, the lead apron is corrugated and pleated together with the aluminum layer.
