What is infrared thermography?

Infrared technology uses the part of the light spectrum the human eye cannot see.

All objects emit infrared light and temperature has a large effect on this. The infrared cameras are sensitive to the slightest variations in infrared light / temperature and therefore have the ability to see what we and normal cameras cannot.

The camera converts this electronically into an image that we can see. In effect we are seeing the temperature of the image hence the term “infrared thermography”.

 Examples: 

This image shows the cameras ability to show internal framework.   We can see the coloring (temperature) is consistent and even throughout the wall.   This is considered a normal temperature distribution and would indicate that there is no cause for concern.

This image shows a significant difference and inconsistent distribution in colour / temperature.   Here the internal wall framing is visible, with warmer areas being highlighted in yellow and colder areas in purple.  The colder / purple areas in the upper corner would be an area of concern and a recommendation for further investigation would be expressed.  NOTE: The purple colour is not always an indication of moisture as the colour is dependant on the ambient conditions. Moisture can also be indicated by a lighter shade of colour.
