  • Leadfree roof flashing material
    Patent number: 5426898
    Abstract: A lead-free plate-shaped roof flashing material comprises a sandwich structure in which a stress damping and stabilizing layer of ductile material is completely covered on one side and at least partly covered on the other side by preferably metallic foil sheetings, e.g. of aluminum foil, designed with densely positioned flattened folded sections having such a form, e.g. closed inverted pleats, that a material layer of each folded section gets into contact with the stress damping and stabilizing layer only when the folded sections open in connection with deforming the flashing material to make it fit to the roofing.
