HOW THERMOGRAPHIC INSPECTIONS WORK
We use Thermography, which measures surface temperatures by using infrared video and still camera. These tools see light that is in the heat spectrum. Images on the video or film record the temperature variations of the building's skin, ranging from white for warm regions to black for cooler areas. The resulting images help us determine whether insulation is missing or there are areas of infiltration. We also offer inspections using our equipment to serve as a quality control tool, to ensure that insulation has been installed correctly. See photos of Images to see the heat loss and infiltration.
A thermographic inspection is done inside and outside the home. We us both to determine the best results under certain weather conditions. Interior scans are more common, because warm air escaping from a building does not always move through the walls in a straight line. Heat loss detected in one area of the outside wall might originate at some other location on the inside of the wall. Also, it is harder to detect temperature differences on the outside surface of the building during windy weather. Because of this difficulty, interior surveys are generally more accurate because they benefit from reduced air movement.
