Thermal Imaging Surveys

Thermal Imaging and How it Works?

Thermal Imaging or ‘Thermography’ has a variety of application across many industries from building and construction to medicine, electrical engineering and renewable energy. The thermal image camera allows the human eye to see infra-red radiation and record clear pictures allowing interrogation, fault finding and analysis.

Thermal imaging cameras are the perfect tool for locating and identifying building failures because they reveal that which would otherwise remain invisible.

Applications for Thermal Imaging

Thermal imaging technology is particularly useful as we explore a building to determine areas of heat loss such as thermal bridging, missing or incorrectly installed insulation, leaks in roofs or pipework, ventilation losses and poorly performing heat distribution equipment.

Fault finding is not limited to the buildings and building fabric. Thermal imaging can be used to source electrical faults. This might be via preventative maintenance by searching for overheating components. Solar PV (photovoltaic) panels can be checked for efficiency and wind turbines checked to avoid catastrophic failure.

When is Thermal Imaging Particularly Useful?

Existing Buildings

Understanding where and to what extent heat loss is occurring:

  • Identifying where heat is being lost due to thermal bridging, defective or missing insulation, natural ventilation etc.
  • Understanding the movement of air through the building.
  • Assessing the effectiveness of heating distribution e.g. underfloor heating, radiators etc.

New-build

Providing peace of mind at critical stages of the build when remedial action can still be easily taken:

  • Checking that insulation is being fitted accurately.
  • Checking for air-tightness and identifying leaks.

Troubleshooting

  • Locating the source of water leaks
  • Find moisture in insulation, in roofs and walls, both in the internal and external structure
  • Detect mould and badly insulated areas
  • Locate water infiltration in flat roofs
  • Detect breaches in hot-water pipes
  • Detect construction failures
  • Monitor the drying of buildings
  • Find faults in supply lines and district heating
  • Detect electrical faults

Overall Benefit of Thermal Imaging

Key to all uses of infra-red imaging is the fast and accurate gathering of information that allows accurate diagnosis and subsequent planning of remedial work.
