Abstract
A flashing arrangement for windows including flashing elements attached to the window frame members for providing a waterproof flashing frame around the window frame. The flashing elements at the top member and side members of the window frame are made of profiles of an elastically deformable material and have a U-shaped cross section, where the first side flange is attached to the outside of the corresponding window frame member, while the other side flange provides sealing abutment with the underside of the surrounding roof. The flashing element at the bottom window frame member comprises an L-shaped profile with an upright flange for connection to the bottom member of the window frame and an outwardly protruding flange which can be connected to a flexible and strip-shaped flashing element of a plastically deformable material. The flashing frame can be manufactured by welding together extruded profile elements made of rubber or a thermoplastic elastomer or can be made in one piece by injection molding.
