What Is Thermal Imaging?

Flir Thermal Imaging Information

Seeing Beyond the Visual

Also called Infrared imaging or Thermography.

Thermal imaging is photography (either on film or digitally).

That captures the image based upon wavelengths of light that have a lower frequency than normal, visual light.

How does thermal imaging work for inspectors?

  • Detecting differences in Thermal Density
  • Water Infiltration
  • Excessive moisture in materials
  • Stud / Joist / Beam / Rafter placement and structure

Difference in Temperature

  • Insulation and insufficiency / unevenness
  • ‘Hot’ electrical panels, breakers, switches and wire connections
  • Heating / Cooling duct placement / insulation
  • Pipe location
  • Pest infestation
  • Energy Audit

Energy Audits


  • Insufficient Insulation
  • Insulation ‘slipping’, compression, movement

Weather Striping

  • Doors, Storm Doors
  • Windows, Frames, Seals, Storm Windows, Caulking
  • Crawlspace and Attic Space


  • Ductwork Insulation
  • Duct Seals
