Thermal imaging uses infrared light detection to generate a colourful thermogram that shows temperature gradients within a certain field. In environmental applications, thermograms provide important information about potential energy, air and water leakage. Because thermal imaging is non-intrusive, it can often be used to identify problems before they become visible. In the case of moisture damage, detection is important to prevent the proliferation of mould within the building envelope.
AirVironment Canada uses thermal imaging to:
Identify moisture intrusion issues which may not be visible without intrusive testing
Pinpoint sources of moisture intrusion or leaks
Identify deficiencies in insulation that are resulting in energy leaks and condensation
Confirm that moisture issues have been addressed and that the building envelope or materials are dry
Thermal imaging can also be used to assess the energy efficiency of a home or commercial building and to identify areas where improvements can be made to reduce heating or cooling loads.
