2. Thermal Imaging & Leak Detection Nigel Hewitt Technical Manager

3. What is Thermography? Infrared Thermography is the science of acquistion and analysis of thermal information from non-contact thermal imaging devices

4. What is a Thermal Image Photography can be described as writing with Light Thermography can be described as writing with Heat

5. Heat Transfer Modes Radiation Conduction Convection Conduction Convection Radiation

6. Infrared Thermography Building materials radiate energy Wet materials retain heat and change slower than dry areas of the same material. This allows us to locate an area with a moisture problem

7. Visual Image These two glasses visually appear the same.

8. Thermal Image Thermal Imaging with an infrared camera. “ Paints a different picture.”

9. Infrared Thermography IR thermography can be used to trace the influx of moisture to find the ultimate source of leakage with little or no physical disassembly of the premises. With current models of IR cameras, images can be made in seconds.

10. Water Damage

11. High Ceiling Water Damage

18. Infrared Thermography IR thermography can then be used to accurately monitor the drying process. IR cameras can inspect places that can’t be physically reached with a moisture meter.

22. Thermal Imaging Where can it help us –Identifying point of water ingress –Track spread of water –Identifying maintenance issues –Identify issues with insulation –Identify areas of air infiltration –Assist with trace and access

26. Moisture Detection on a Roof

27. Damaged/Missing Insulation

28. Building Envelop Inspection

29. Water leak in a concrete slab

30. Hydrogen Tracer Gas Leak Detection Acoustic Leak Detection Additional Equipment

31. Non-Destructive Moisture Detection Advantages –Quick –Non-evasive –Does not require relocation of the occupant or the occupant’s contents –Helps define actual source and defines its progression Disadvantages –Cannot see through walls; only detects surface temperature differentials –Cannot detect subsurface damage (i.e. mould or structural damage)
