First, the fancy way: infrared photography can identify temperature changes on different parts of the house, and thus heat losses. With proper interpretation of the photograph you can know which heat losses are caused by air leaks and which by missing or soaked insulation. This is like an X-ra...
Ice Dams are a serious problem throughout Canada, although it varies from year to year as to which region gets hit. Here we visited one of the solution companies who work to seal up the primary cause of ice dams, the warm air leaks into the attic. For more background on the problem check out th...
