What is Thermal Imaging?

Everything in the world that is above absolute zero (-459.69⁰F) emits thermal energy (radiation).
Thermal imaging is the gathering and analysis of thermal radiation by means of non-contact equipment.
The scans are safe, the cameras are passive devices and display data as a thermogram (a thermal map). This assigns colors to the various levels of energy.

There are many advantages to using thermography. The camera is passive, meaning it emits nothing. Thermal scans can be performed without interruption to facilities or equipment operation. Scans will see what the human eye can’t, they can identify problems, or confirm that there are no apparent problems. Thermal imaging has been used by the military and law enforcement for decades.

There are a variety of practical applications for thermal imaging; below is a list of some of the more common uses:

  • Find missing insulation
  • Locate areas of energy loss, (e.g. windows, doors, etc.)
  • Identify air/gas leaks
  • Identify areas of moisture in walls and roofs
  • Identify leaking supply ducts
  • Evaluate in-floor radiant heating
  • Identify failing electrical devices
  • Identify leaking pipes or valves
  • Verify reinforcement in concrete
  • Locate rodent/pest infestation
  • Pre-sale real estate scan
  • Benchmark a building (for future use as a comparative)


  • A phone interview to discuss potential building problems. This is set to help go over any areas of concern before inspection.
  • Facility walk-through on day of inspection. The inspector will walk the facility with the Owner (or Owner’s Representative) upon arrival.
  • Inspection by a Certified Thermographer. There will be a thorough inspection of the site.
  • Images of anomalies. Images are captured (for later analysis) using a Thermal Camera.
  • Moisture analysis of anomalies (if necessary). If an anomaly is suspected to be moisture related, a moisture meter will be used to verify, and quantify.
  • Dew Point Detection. Wall surfaces that are at the dew point (the point where moisture condensates) can lead to mold problems. All inspections will detect wall temperatures that are near or at the dew point.
  • Off-site analysis of images. Once the inspection is complete all captured images will be analyzed.
  • Hard-copy detailed report. Upon completion of analyzing all images, the client will be sent a report that contains all relevant images along with comments.


Anyone can buy a thermal camera and take images. But not everyone has the expertise to deliver comprehensive and thorough analysis and results. Hansen’s thermographer is officially certified, and has passed testing that meets the American Society for Nondestructive Testing (ASNT) recommended practice SNT-TC-A1 recommendations for training. He also has extensive building science training, and has over 35 years of experience in the construction industry (over 20 years of experience in building envelopes). He is also a former Guest Faculty at Lawrence Technological University.

We look forward to working with you on your thermal imaging needs. Call 800-552-4877 to inquire.
