What does a thermal imaging camera do?
Thermal imaging is a brilliant device that shows us heat differentiation. As you will see in the image below it shows us different colour for different temperatures through out the picture. The “red” section shows us the warmer parts of the photo, and the “blue” section shows us the cooler part of the photo.
In the diagram below is a roof leak that was present and the blue circle in the centre of the photo is where the water is pooling. We knew the leak was there but with thermal imaging we can see the extent of the water ingress.
Thermal imaging is also used to show us if insulation is missing, plumbing is blocked or ideally it can show us termite activity within a wall cavity or roof space. Termites are warm blooded therefore show up on the thermal camera as a red line. This red line is in fact a termite trail. If a blue section appears it could be old termite damage.
