Thermal Imaging & Trace & Access Nick Jeffery Training Manager
What is Thermography? Infrared Thermography is the science of acquistion and analysis of thermal information from non-contact thermal imaging devices
What is a Thermal Image Photography can be described as writing with Light Thermography can be described as writing with Heat
Heat Transfer Modes Radiation Conduction Convection Conduction Convection Radiation
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
Visual Image These two glasses visually appear the same.
Thermal Image Thermal Imaging with an infrared camera. “ Paints a different picture.”
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.
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
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
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
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.
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.
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
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)
