Thermal Imaging

The human eye is capable of capturing only a very small portion of the light spectrum. Thermal imaging expands the visible spectrum of the human eye by providing a color coded picture of the invisible spectrum. In other words, you get a picture showing the temperature differences of a surface.

Nationwide uses thermal imaging as a non-destructive way to inspect structures, mechanical systems, heating and air systems, and plumbing. Following are a few of the thermal imaging applications that Nationwide specializes in:


Roofs can be inspected to detect substructure moisture. Roof damage allows water to seep into the substructure. Early detection of leaks is essential in minimizing costly roof repairs. Thermal imaging will show moisture since water soaked materials will heat differently than normally dry roofing materials.


Thermal imaging can be used to detect heat loss from a home or business as a result of poor insulation. It will highlight areas that need attention when weatherproofing a structure.

Refrigeration Systems

Thermal imaging is used to detect air leaks and clogged condenser tubes in refrigeration systems.


Water leaks from a plumbing system can leak undetected until major damage has occurred. We can scan in, under, and around plumbing fixtures to determine if there is active leaking going on. Thermal image scanning can detect temperature anomalies in the plumbing system not visible to the naked eye. We can use thermal imaging to detect moisture in structure walls that may possibly be caused by plumbing pipe leaks.

Heating and Air Conditioning

Thermal imaging is helpful for finding problem areas quickly in heating and cooling systems and can be used to dramatically improve the efficiencies of the system. We can detect issues with airflow, blockages, and leaks.

Bed Bug Heat Treatment

We use thermal imaging when treating homes or businesses for bed bugs. We fully seal up a building and then provide high temperature treatment to kill bed bugs. The thermal images ensures we have a tight seal so that we can increase the temperature of the building to a required level to kill the bed bugs.

Building Diagnostics

Poor or inadequate insulation, moisture, building envelope leaks, and substandard work are costly to residential and commercial building owners. An infrared camera can help you quickly see where energy efficiency can be improved. Infrared cameras make it easy to improve energy efficiency and locate repairs with minimal disruption. Infrared cameras instantly show you what is wet and what is dry and can help find the sources of trouble with minimal impact to people and buildings.

Energy Auditing and Inspection

Air Tightness and Thermal Imaging testing are important quality control measures when building or renovating a house. Heat losses in buildings can account for up to 50% of the total energy consumption and come from air leakage through chimneys, attics, wall vents and badly sealed windows/doors. All new buildings must meet air tightness requirements of the Building Regulations. By reducing air leakage, you will obtain a better comfort in the building. The building can also be heated and cooled more efficiently to conserve energy and save money.

Manufacturing Industries

At manufacturing facilities, we use thermal to inspect countless number of production equipment and components as well as the complete electrical power supply system. Inspections are done with the production process in full operation. In many cases the use of a thermal imaging camera can help optimize the production process itself.

Some examples of mechanical equipment where thermography is used:

  • Pumps (overheated connections, fuse problems, overloaded electrical cables etc)
  • Process valves (open, closed, leakage)
  • Storage tanks (sludge levels)
  • Pipelines (check if and where there are anomalies, for example locate build up of scale etc)
  • Motors (overheating bearings, misalignment, overheated windings)
  • Conveyor belts (overheated bearings)
  • Furnace inspections (with a special camera designed to “see through flames” for high temperature industrial furnace applications, ideal for monitoring all types of furnaces, heaters and boilers.)
  • Electrical Equipment

Some examples of electrical equipment where thermography is used:

  • Primary power source i.e. outdoor high voltage switchyard
  • Switchgear
  • Transformers
  • Low voltage installations i.e. breaker panels, faulty electrical outlets/wall sockets
  • Fuse panels
  • Motor control centers (MCC)
  • Electrical cabinets
