Zusammenfassung:A roofing shingle having fire resistance material added to the shingle in a localized area includes a substrate having a first portion and a second portion, a first asphalt-based coating impregnating the first portion, the first asphalt coating including a fire retardant material, and a second asphalt-based coating impregnating the second portion, the second asphalt coating containing less of the fire retardant material than the first asphalt coating. Un bardeau de sciage avec du matériau ignifuge ajouté dans une zone localisée comprend un substrat ayant deux parties. La première partie est imprégnée dune première couche dasphalte qui comprend un matériau ignifuge et la deuxième partie est imprégnée dune deuxième couche à base dasphalte qui contient une quantité de matériau ignifuge inférieure à celle de le première couche dasphalte.
