Infrared Imaging
The thermal imager is a camera that produces pictures based on the temperature difference between surfaces. Especially when used during a blower door test, thermal imaging is the most effective means of locating hidden insulation and air leakage problems. This test does have its limitations: it becomes less effective if the indoor and outdoor temperatures are within a few degrees. For this reason, we may recommend that you schedule your audit during a particular time of day when the temperature difference will be the greatest.
