With energy costs rising a thermal imaging survey can give homeowners answers as to why their property feels cold and where heat is being lost. This non-invasive technique identifies air leakage pathways, cold bridging and insulation defects.

Thermal imaging cameras detect radiation that is emitted from all objects and produce visual images of those differences in temperature called thermograms. Warmer objects show up better in these images due to the higher levels of radiation they emit. Warmer objects appear as bright colours and cooler objects are shown in darker shades. These images can be interpreted by an ABBE-qualified building thermographer to identify faults.

The Essential Guide to Conducting a Thermal Imaging Survey

When carrying out a thermal imaging survey the weather conditions must be suitable. This is because the survey relies on good contrast between internal and external temperatures. It is also important that the surface of the structure is dry to prevent moisture from distorting the results.

Winter is the best time of year to carry out a thermal imaging survey as outdoor temperatures are cold and indoors are warm. This gives the best possible contrast for identifying areas of heat loss within properties.

For anyone looking to reduce their energy costs, a thermal imaging survey is an excellent investment. As well as highlighting areas where insulation is deteriorating, it can help to identify air leakage pathways that need fixing, reducing energy bills significantly. This can pay for the cost of the survey many times over, saving on costly heating bills and reducing carbon emissions.
