Thermal imaging cameras for building inspections - .PDF file.

Leicester City Council has bought two Flir B425 infrared cameras in order to bring the thermographic inspection of its building structures in-house and thus save it from spending money on specialist consultants.

These infrared cameras’ initial role was checking the status of lath and plaster ceilings, however the council’s buildings surveyors are now seeing its potential for a wider range of inspection, detection and energy management tasks.

To prevent its lath and plaster ceilings of buildings in its care from collapsing, the council began a regular inspection programme that was improved by the introduction of thermal imaging — for which it previously employed external consultants.

With its own Flir infrared cameras, Leicester City Council is making cost savings by bringing this work in-house. 

Key benefits of product application

  • Thermal Imaging is non-destructive and can be done when the building is fully occupied
  • The B452’s 50mK sensitivity detects any air gaps in the lath and plaster ceilings
  • The camera’s Panorama function has enabled Leicester City Council surveyors to see the whole elevation of a building as a single, composite shot, which is good for identifying sources of heat loss
  • The B425 has also been used to identify mould growth areas, leaks and water ingress
  • It has checked the integrity of insulation, air tightness and overall energy performance of buildings
  • The camera’s building analysis software, Build IR, has provided energy loss calculations

FLIR Systems specialises in technologies that enhance perception and awareness.  The company brings innovative sensing solutions into daily life through its thermal imaging and visible light imaging technology and systems for measurement, diagnosis, location and advanced threat detection.  Its products improve the way people interact with the world around them, enhance productivity, increase energy efficiency and make the workplace safer.

FLIR Systems has six operating segments – surveillance, instruments, OEM and emerging markets, maritime, security and finally, detection. Of these six, ‘instruments’ is of greatest interest to trade and industry and the second largest segment in the company’s portfolio. This division provides devices that image, measure and assess thermal energy, gases and other environmental elements for industrial, commercial and scientific applications.

These products are manufactured across five production sites, three in the USA and two in Europe; Sweden and Estonia.

A model to suit every application and budget
The options that FLIR Systems provides for measuring temperature and studying thermal performance have never been greater.  Not only does the company offer a huge range of models to suit all thermal application needs but the technology is also affordable and very easy to use.  Thermal cameras now come in various shapes, sizes and degrees of sophistication and FLIR continues to invest heavily in the development of new and complementary technologies to differentiate itself from competitors.

An important milestone in the development of thermal imaging has been the introduction of the FLIR Lepton® core, a micro longwave detector, the size of a mobile SIM.  This has allowed thermal imaging to be repackaged to meet the needs of an even wider audience and, in combination with another new technology called Infrared Guided Measurement – IGM™ – has led to the development of a range of test and measurement meters with imaging capability.

Another important growth area for FLIR thermal imaging is in continuous monitoring to assure quality and safety.  Through its introduction of discrete fixed mounted thermal cameras which are fully compliant industry standard plug-and-play protocols, FLIR Systems has provided industry with infrared machine vision which is instantly ready for quick and easy network installation.

Protecting assets and people from fire is an area for which thermal imaging is least known but, thanks to FLIR Systems’ development, it is now one of the most cost-effective methods available.  Its application flexibility and rapid return on investment present an attractive proposition for any site or safety manager.
