Infrared is the use of a special camera that can “see” on the infrared energy spectrum of light. Infrared energy is emitted by heat and so the IR camera will detect thermal anomalies associated with how much head a certain material is emitting. A trained thermographer can determine from these anomalies what they represent and interpret the findings e.g., missing, or nonperforming insulation, air infiltration and water leaks. If you are being offered an IR inspection, be sure to ask the inspector if they have training i.e., certifications to use the camera. Examples of this training would be, Level I Thermographer, Level II Thermographer, CRT- certified residential thermographer.
