What is Infrared Thermal Image Scanning?
Thermal imaging uses infrared technology to detect very small differences in temperature. Every material has a unique thermal signature. When moisture, heat, or cold are introduced into the structure the thermal signature changes. With the help of this incredible camera we can see many things that simply are not detectable to the naked eye.
Cold areas behind walls, floors, or ceilings can indicate the presence of moisture, or lack of insulation and the infrared camera helps us diagnose these problems easily. Thermal imaging also easily detects overheating circuits, fuses, or circuit breakers. In some cases, flat roof leaks, or leakage under, or behind plumbing fixtures can also be found.
What Thermal Image Scanning is NOT
MOISTURE METER – The infrared thermal imaging camera is NOT a moisture measuring device.
X-RAY VISION – The infrared thermal imaging camera is NOT an X-ray device. It measured heat differentials and cannot see through objects like an X-Ray machine.
SILVER BULLET – The infrared thermal imaging camera does NOT completely remove the risks of concealed damage, but it GREATLY increases the thoroughness of your home inspection
Here’s how Infrared Thermal Imaging works to find hidden problems:
Utilizing state-of-the-art infrared thermal cameras allow us to highlight and analyze problems, store images for insertion into your report and document the results. Very few inspection firms offer this service. We are proud to be an exception.
|The thermogram (left) clearly shows insulation missing in a bedroom ceiling. The ceiling is a vaulted type with limited access in the attic so an inspection would not be possible from that view point. However, the deficiency could not hide from the infrared camera. This particular home contained a number of areas with missing insulation – and it was a brand new home, only one year old. Not only does the missing insulation allow conditioned air to escape resulting in higher energy consumption and costs, but it can allow fungal growth due to condensation on the drywall in the attic.|
In addition to missed insulation, water leaks and overheating electrical components, an infrared scan can even discover things covered up by drywall by mistake. The photos above clearly show how the drywall subcontractor covered over a heating/air conditioner duct. The client complained over and over to the builder (this was a brand new home) about how the room was never conditioned properly. A quick scan with the infrared camera revealed that the duct was completely covered.
