An impact resistant roofing shingle which includes an asphalt coated substrate whose unexposed surface is laminated to an organic film. A process of forming that shingle includes the step of applying an organic film, by spraying a latex, by applying a rubber polymer modified asphalt, by compressing a plastic film having a higher melting or decomposition temperature than the melting point of the asphalt coating or by applying an adhesive to which a plastic film is applied to the unexposed surface of the asphalt coated substrate.
L'invention concerne un bardeau de toiture résistant à l'impact qui renferme un substrat recouvert d'asphalte, dont la surface non exposée est laminée sur un film organique. Cette invention a aussi pour objet un procédé de formation dudit bardeau comprenant l'étape d'application d'un film organique qui repose sur la pulvérisation d'un latex, l'application d'un asphalte modifié par un polymère caoutchouteux, la compression d'un film plastique possédant une température de décomposition ou de fusion supérieure à celle du point de fusion du revêtement d'asphalte ou l'application d'un adhésif, sur lequel est disposé un film plastique au niveau de la surface non exposée du substrat recouvert d'asphalte.
