Infrared thermography (IRT)

Infrared thermography (IRT)

Over the years, home inspection tools have been developed to make inspectors’ jobs easier. Moisture meters, AFCI/GFCI testers, CO analyzers, PPE, and many more have all helped shorten the amount of time it takes for an inspector to complete a job. Some of these tools made the job safer, some made it faster, and some allowed inspectors to add new services with their reports. Thermography and infrared technology fits all of these categories and has become a leading service that all inspectors should be trained in.

What Is Infrared Thermography (IRT)?

Infrared Thermography (IRT) is the science of capturing and analyzing heat (thermal) information using non-contact infrared (IR) tools. All objects above absolute zero emit IR radiation, which can’t be seen with the naked eye — that’s why specialized thermal imaging cameras are used.

The general advantages of IRT are the following:

  • IRT is a non-contact technology; the devices do not to be in contact with the sources of heat creating a safer work environment.
  • IRT creates a two-dimensional thermal image that allows for comparisons with visible light cameras
  • IRT works in real-time, allowing high-speed scanning of images
  • IRT is non-invasive and will not disturb or affect the target area
IRT had widespread use as a military technology in the 1970’s but found itself in commercial use soon after. Today the technology is employed in various fields including medicine, surveillance, engineering, and building diagnostics, which includes home inspections. For home inspectors, knowledge of training of IRT can help diagnose defects that may not have been apparent in a routine inspection, reveal further defects and underlying causes, and can make the job safer.

Specialized Instruments for Detecting Heat Signatures

Infrared imaging or thermography uses specialized instruments that detect and visualize heat spectrums that allow home inspectors to follow the flow of heat through a system. Such instruments include the following:

Spot Radiometer

Also known as a point radiometer, these devices are used to measure single points in the home. The home inspector then compiles the data to determine where there are fluctuations in temperature.

Thermal line scanner

As the name suggests, this device shows a line image of thermal variations superimposed on a scanned area.

Thermal imaging camera

An infrared camera produces a thermal picture of an area that displays heat leakage in greater detail than spot radiometers and thermal line scanners.

Applications of IRT in Home Inspections

As a home inspector, it is our job to identify serious defects, but sometimes defects may be completely hidden in plain sight. When included in routine inspections, IR cameras can assist inspectors in identifying these hidden defects. Understanding the principles of IR and how to interpret data will help you create a more complete report.

Here is a list of some applications for IRT

  • Determine if insulation is lacking or deficient
  • Determine if there are any air-leaks or abnormalities in heat flowing out of a building
  • Determine if there is any moisture intrusion with insulation or other systems (when used with a moisture meter)
  • Determine if electrical systems are overloaded or overheating
  • Determine if there are leaks or defects with the roof
  • Determine defects with the HVAC system

Infrared tools reveal what the eyes can’t see — but only when used by trained professionals.
