What Are the Primary Applications for Thermography?
In the thirty years thermography has been used to solve building problems, a number of major applications have been developed. These include: Insulation checks Moisture Intrusion Building Structural Verification HVAC Performance Electrical Overheating Air leakage location Rodents Insulation checks Missing, damaged or non-performing insulation will stand out clearly in a thermal image when there is at least a 18F (10C)temperature difference between the conditioned space and the outside air. The inspection is done from both inside and outside, with the best results usually gained from inside where the thermal patterns are more distinct. When work is done in the daytime or early evening, the impact of solar loading must be considered. The effects of the sun can remain on a wall six to eight hours after sunset. Wind must also be reckoned with as it can quickly eliminate the thermal difference on an exposed surface. Keep in mind that wind can also enhance thermal patterns, especially those
