J’ai remarqu\u00e9 que cet hiver a produit une \u00e9norme quantit\u00e9 de gla\u00e7ons et les barrages de glace \u00e9taient devenus un gros probl\u00e8me pour de nombreux propri\u00e9taires.<\/strong><\/p>\n\n

Qu’est-ce que le barrage de glace?<\/strong><\/p>\n\n

La chaleur s’\u00e9chappe des parties mal scell\u00e9es ou mal isol\u00e9es du toit, faisant fondre la neige au-dessus. \u00c0 mesure que la neige fond, elle coule le long du toit jusqu’\u00e0 ce qu’elle rencontre de la neige non fondue sur un espace non chauff\u00e9 sur le toit. L\u00e0, il va s’arr\u00eater et regeler. Ce processus se poursuivra jusqu’\u00e0 la formation d’un barrage de glace. <\/p>\n\n

Pourquoi les barrages de glace sont-ils probl\u00e9matiques?<\/strong><\/p>\n\n

Ces barrages font en sorte que l’eau qui coule le long de la partie chaude du toit s’\u00e9coule derri\u00e8re le barrage et remonte sous les bardeaux. Une fois que l’eau du barrage de glace passe sous les bardeaux, elle est libre de fuir dans le plafond et le mur. Bien qu’elle soit p\u00e9riodique (\u00e9ventuellement, le temps se r\u00e9chauffera, arr\u00eatant ainsi la fuite), cette intrusion d’eau peut devenir co\u00fbteuse. Si rien n’est corrig\u00e9, des dommages caus\u00e9s par l’eau se produiront au moins pour les finitions du plafond ou du mur, et au pire, il y a un risque de pourriture structurelle. <\/p>\n\n

Comment peut-on pr\u00e9venir les barrages de glace?<\/strong><\/p>\n\n

Il y a deux grandes mesures pr\u00e9ventives \u00e0 prendre en compte lorsque l’on aborde la question des barrages de glace.<\/p>\n\n

1. Ajout d’isolation du grenier<\/strong>: Cela fonctionnera bien en fonction du grenier en question. Cependant, certains greniers ont tellement de fuites d’air chaud qu’il serait impossible d’ajouter suffisamment d’isolation pour r\u00e9soudre le probl\u00e8me. <\/p>\n\n

2. Sceller les chemins de fuite d’air dans l’espace du grenier<\/strong>: Dans de nombreux cas, avec des outils d’\u00e9tanch\u00e9it\u00e9 appropri\u00e9s, un propri\u00e9taire peut s’occuper de cette t\u00e2che lui-m\u00eame. Cependant, certaines instances n\u00e9cessitent un sp\u00e9cialiste pour trouver et r\u00e9soudre le probl\u00e8me. Les voies de fuite d’air courantes comprennent les trappes d’acc\u00e8s au grenier, les luminaires de plafond comme les lampes \u00e0 pot et les chemin\u00e9es de plomberie.<\/p>\n","protected":false},"excerpt":{"rendered":"
