Infrared (IR) Thermography (also known as an infrared thermal scan) is a useful tool to help find anomalies that may otherwise remain hidden in walls, floors and ceilings. Infrared energy is heat energy. A properly trained infrared thermographer can interpret an infrared image and determine if a roof or plumbing leak exists, if there is missing wall or ceiling insulation, if an electrical component is reaching critical temperature levels, or if no major issues exist at all. The purpose of most thermography work, as performed by home inspectors, relates to looking for anomalies within a building. An anomaly is a situation that is otherwise not to be expected under normal conditions.
An infrared camera is a non-contact device that detects infrared energy (heat) and converts it into an electronic signal, which is then processed to produce a thermal image on a video monitor and perform temperature calculations. Heat sensed by an infrared camera can be very precisely quantified, or measured, allowing you to not only monitor thermal performance, but also identify and evaluate the relative severity of heat-related problems. Recent innovations, particularly detector technology, the incorporation of built-in visual imaging, automatic functionality, and infrared software development, deliver more cost effective thermal analysis solutions than ever before.
