What is Thermal Imaging?
Infrared technology is a form of photography that sees part of the light spectrum the human eye cannot see. All objects with a temperature above -273° Celcius (0° K) emit thermal radiation. Most of the emitted thermal radiation belongs to the IR region of the spectrum. This IR radiation is invisible to the eye and require specific technology to detect it.
Put in simple terms, thermography means “writing with heat”. Thermal imaging cameras are very sensitive to slight variations in IR radiation, this gives us the ability to create an image that could not otherwise be seen by the human eye.
Because our cameras are detecting naturally emitted radiation, we can detect moisture in a building in a Non-Destructive way. This saves both time and money.
What the human eye sees...
In the image here we see a blank wall. There is no sign of any dampness, but how can you be sure?
What an IR camera sees....
Here is a rendering of IR radiation. We can see much more than we can with the human eye.
Here we can see the wall framing. To the lower part of the image there is a cooler patch in purple. In this case it is caused by a side table drawing the heat from the wall. We can, with some confidence suggest there is no water ingress in this image.
