Dam Ice: The Frost Factor
| Division: | Engineering & Computing Sciences | | Category: | Intermediate | | Region: | Northwestern Ontario | | City: | Thunder Bay, ON | | School: | Sir Winston Churchill Collegiate and Vocational In | | Abstract: | This experiment investigated why ice dams occur on some roofs during winter and the diagnostic properties of observed frost melt patterns on the roofs of storey-and-a-half houses. Heat loss patterns were measured on a model roof proving that ice dams are most likely to form above the knee wall. |
