Woods Engineering uses infrared imaging technology to assist in the detection and diagnosis of building deficiencies. The nondestructive technique is primarily used to detect the presence of moisture in roof insulation and within wall cavities. As the construction materials cool during the daily thermal cycle, those which contain undesirable moisture retain heat longer and can be detected with the use of an infrared camera. The technique is also used to check for the presence (or lack of) wall and ceiling insulation, can be used to evaluate the grouting of concrete masonry unit walls, and can check electrical systems for thermal anomalies.
