LOCATE THE INSULATION GAPS

ISSUE: Incomplete insulation allows heat to be conducted and radiated through walls and roofs.

SOLUTION: Look at condensation patterns or rain-drying patterns on the walls and roof. If one part dries more quickly than the rest, typically a sign that heat’s escaping there, you may be missing some insulation. You can also buy a thermal camera from Seek or FLIR. Both companies make attachments for smartphones that cost much less than a stand-alone camera, since they use your phone’s screen and memory. I find the blackand-white setting easier to grasp than the colour. On mine, the darker the image appears, the colder the surface. Hold it up to an area inside your house and the dark spots (in my case) will reveal any air leaks or missing insulation.
