Benefits of Thermal Imaging as Part of Property Surveys

Thermal imaging surveys involve the use of thermal imaging cameras to visually represent surface temperatures of building materials in order to identify thermal anomalies that indicate possible defects such as dampness or temperature variations that could indicate missing or wet insulation.

Kelleher & Associates have made extensive use of this technology for several years now and use thermal imaging cameras as standard during pre-purchase structural surveys. Successful thermography requires image interpretation and for this reason we have undergone training in this specialist area to ensure that the information provided by the camera is being correctly used as a diagnostic tool. These cameras should not be used by an amateur. Frequently, in cases of rising damp, a damp meter will be used alongside the camera as a form of back-up to verify the moisture content of masonry materials. In a recent survey, hidden water infiltration due to a damaged roof was identified behind plasterboard, the outside surface of which appeared undamaged.

The accompanying image shows a plasterboard lined external wall. Fixing points can be clearly seen, as well as the outline of timber battens between which insulation is very likely fitted (based on the temperature of the plasterboard surface). The darker line at the top of the plasterboard shows a gap in insulation cover rather than dampness. The image is information rich illustrating that these cameras are a powerful tool to the trained building surveyor.

Thermal Imaging Surveys are also very useful in determining where heat losses are occurring through the external envelope of a building.
