Thermal Imaging Inpection

Benefits of Thermal Imaging

Infrared thermography (commonly called infrared imaging or thermal imaging) is an advanced, non-invasive technology that allows an inspector to identify deficiencies in buildings that can’t be revealed using conventional visual inspection methods.

Thermographic cameras detect radiation in the long-infrared range of the electromagnetic spectrum and produce images of that radiation. The amount of radiation emitted by an object, called “Emissivity”, increases with temperature; therefore, thermography allows for variations in temperature to be identified.

Thermal Imaging can help identify

Energy loss

  • Missing, poor, settled, or improperly installed insulation
  • Heat loss and air infiltration in walls, ceilings, floors, windows and doors
  • Damaged and/or malfunctioning radiant heating systems
  • Air-conditioner compressor leaks
  • Missing framing members and other structural defects that can lead to energy loss
  • Broken seals in double-pane windows
  • Flu leaks
  • Leaking air conditioning ducts or mechanical equipment

Moisture related problems

  • Plumbing leaks
  • Building envelope water intrusion (roof, walls, windows, doors, and foundation)
  • Wet insulation, cabinets, walls, flooring, and personal/business items

Electrical deficiencies

  • Circuit breakers in need of immediate replacement
  • Overloaded and undersized circuits
  • Overheated electrical equipment and components
  • Electrical faults

Identification of Pests

  • Possible pest infestation, as revealed by energy loss through shelter tubes left by boring wood-destroying insects
  • Animals such as snakes, bats, rats, mice, squirrels, raccoons, opossums, etc. inside of walls, attics, and crawl spaces

Location of building components

  • Stud/ joist/ beam placement
  • Pipe location
  • Heating and cooling duct placement

*Please note that FSG predominantly uses thermal imaging to find moisture damage and pipe leaks.*

Thermal imaging limitations

  • Images can be difficult to interpret accurately when based upon objects with erratic temperatures
  • Accurate temperature measurements are hindered by differing emissivity’s and reflections from other surfaces
  • Thermal imaging is only able to directly detect surface temperatures (It cannot see through walls like an x-ray scanner)
  • Conditions of the jobsite can have a substantial effect on thermal imaging (If it has just rained, early morning temperatures vs afternoon temperatures, very cold or hot environments, etc.)
