2 Thermal Imaging & Trace & Access Nick Jeffery Training 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

12 Grey Scale

13 Temperature Range Camera is operating in Composition of Photo Focusing of the Picture

14 Colour Palette


16 Isotherm

17 Altered Isotherm Range

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.

19 Water Damage

20 See the Drying taking place! Dry a building more effectively and more efficiently! The Drying Process


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

23 The Drying Process



26 Moisture Detection on a Roof

27 Damaged/Missing Insulation

28 Building Envelop Inspection

29 Water leak in a concrete slab

30 HVAC & Plumbing With thermal imagers it's easy to scan an entire building to see the relation of HVAC system, building envelope, and plumbing issues

31 Building Diagnostics Buildings may be quickly and thoroughly scanned using a thermal imager, identifying problem areas that can't be seen by the naked eye

32 Energy Auditing & Home Inspection Excessive air leakage can account for up to half of the energy consumed to condition buildings. The leakage pathway is often complex and, without thermal imaging, extremely difficult to visualize.

33 Property & Facility Management Thermal imagers are a valuable tool in predictive maintenance of electrical, mechanical, and structural systems, to detect problems, prevent downtime, guide corrective action, and increase work safety.

34 Moisture & Restoration The presence of moisture in building envelopes, either from leakage or condensation, can have serious consequences. With infrared images, water damage is easily detected

35 Hydrogen Tracer Gas Leak Detection Acoustic Leak Detection Additional Equipment

36 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)

37 Final Points How Much Does The Service Cost What Coverage Do We Have
