Thermal imaging uses infrared technology to identify very slight differences in temperature. All material has a unique thermal signature. When moisture, heat, cold or termites and other insects are introduced into the structure the thermal signature changes. The changes can be subtle or dramatic but with thermal image scanning the differences are detectable where they wouldn’t be able to be seen with the naked eye and it’s also great to identifying areas where insulation is inadequately in the attic, crawlspace and walls.
Thermal image scanning technology is now being used to evaluate residential and commercial buildings. As a non-invasive testing tool it can quickly help detect where there are possible issues. This helps limit the areas of concern and it also saves time and less destructive discovery is needed.
What Thermal Image Scanning is not?
The infrared thermal imaging camera does not provide the operator with x ray vision and it is not a moisture meter even though it is used as an aid in detecting areas of concern. A thermal imaging camera helps identifies thermal anomalies but it does totally eliminate the possibility that damage, leaks and other concerns may not be identified during an inspection. When used with other tools, equipment and experience thermal imaging has helped identify issues that are rarely identified during a standard comprehensive home inspection.
