Moisture & water damage
12.1.1
General
It is often possible to detect moisture and water damage in a house by using an infrared
camera. This is partly because the damaged area has a different heat conduction property
and partly because it has a different thermal capacity to store heat than the surrounding
material.
Many factors can come into play as to how moisture or water damage will appear in an in-
frared image.
For example, heating and cooling of these parts takes place at different rates depending
on the material and the time of day. For this reason, it is important that other methods are
used as well to check for moisture or water damage.

Figure
The image below shows extensive water damage on an external wall where the water has
penetrated the outer facing because of an incorrectly installed window ledge.
12.2
Faulty contact in socket
12.2.1
General
Depending on the type of connection a socket has, an improperly connected wire can re-
sult in local temperature increase. This temperature increase is caused by the reduced
contact area between the connection point of the incoming wire and the socket , and can
result in an electrical fire.
A socket’s construction may differ dramatically from one manufacturer to another. For this
reason, different faults in a socket can lead to the same typical appearance in an infrared
image.
Local temperature increase can also result from improper contact between wire and sock-
et, or from difference in load.
