| This building was scanned before and after renovations. Before knowing what the renovation was, I guessed that they added rigid insulation to the wall. This is common during envelope retrofits in Yellowknife, NT, Canada, but I found out later that only an air barrier was added. The windows were also changed. The cladding was changed from wood to painted metal. As can be seen, there are significantly less thermal anomalies on the wall but I don't know how much of the change is due to the metal cladding and how much is due to the air barrier. Any thoughts? It is now very difficult to spot the wall members, for example, but thermal bridging hasn't changed because no insulation was added. |
