Abstract

Une bande chauffante dissimulée (10) pour fournir de la chaleur à l'arête d'un toit pour prévenir la formation de glace. Chaque bande chauffante comprend une pluralité d'assemblages triangulaires (110) ayant un câble chauffant (28) inséré du dessous de l'assemblage et positionné à côté d'un panneau frontal échancré (16). Des agrafes de maintien s'étendent depuis une partie basse et un panneau sommital troué est disposé au-dessus du câble chauffant. Des chevrons de renfort espacés (24) sont localisés entre les panneaux latéraux (12, 13) des assemblages pour supporter des bardeaux (46) et éviter l'affaissement. La bande chauffante est placée entre des rangées de bardeaux et n'est pas facilement visible depuis le sol.
