Infrared Thermal Imaging
Infrared thermal imaging allows an inspector to find problems and deficiencies that may not be apparent to the naked eye. An infrared inspection may reveal moisture intrusion, missing/deficient insulation, heat and energy loss, air leakage points, and potential electrical hazards.
The infrared camera detects infrared radiation wavelengths. Each wavelength is related to a specific temperature and assigned a color. The color gets brighter as the temperature increases. The inspector can then view these temperature differences with the infrared thermal imager and make evaluations based on what is found. If there is an area that appears to be a possible moisture signature, further testing can be done with a moisture meter.
Infrared thermal imaging is not x-ray vision, but it often allows an experienced inspector to find items that otherwise may be undetected. Don't get stuck with hidden defects. Hire an experienced inspector that uses IR thermal imaging.
