Thermography

Thermography or Thermal Imaging is a where heat is visualised, looking though the eyes of a camera that is designed to detect infrared radiation.

It is a powerfull means for investigating 'energy performance' of materials and systems by looking at their behaviour on conduction and radiation of heat.

Applications for thermal imaging are numerous. Next to locating underfloor water leakages, building inspections for heat loss is probably it's most popular. Unexpected heat-loss and condensation are typical issues we're dealing with on a daily bases.

It is essential that thermographic inspections are carried out by qualified and experienced specialists only. At EcoScan we are Level 2 certified and registered thermographers and use state of art equipment only.
Working methods according to ISO6781:1983 for Qualitative Detection Building of Thermal Irregularities in a Building Envelope.,

*        Infrared explained

From your physics class you might remember that all materials are build up from molecules.
That these molecules consist of atoms and these atoms consist of even smaller particles: electrons, neutrons and positrons.
Perhaps it was also mentioned that these particles have an electrical potential and their constantly rotating and jumping up and down causes electro magnetic fields (EMF). To explain infrared we have to take it a bit further.
At the theoretically lowest temperature possible of –273.15° Celsius these particles are steady and don’t cause any EMF but as soon as the temperature rises these elements start to become active again. The higher the temperature is, the more activity and the higher the EMF.
Of course these vibrations are not all the same and we find them across the whole spectrum of different frequencies mainly depending on the type of material.

Now there is a particular range of frequencies wherein these vibrations create strong EMF or so to say……..are very energy intensive. We can only ‘receive’  this energy via the materials’ surface. In plain language we call this experience: ‘feeling the heat’ or ‘sensing radiation’. Energy is being emitted by the surface. 

Back to infrared. An infrared camera senses the EMF in that part of the spectrum that contains this energy. We call this the ‘infrared’ part of the spectrum. Your digital camera does in fact the same (or your eye, which is a very sensitive optical measuring instrument as well) but then in the ‘visible’ range of the spectrum. Funny enough these two ranges are next to each other and in the situation that an object emits a very high level of energy (HOT!!) 

If temperatures keep rising it is even possible that energy is being emitted in the visible spectrum. We call this glowing.

The frequencies and their intensity that your eye and your photo camera detect are being interpreted as colours and light intensity.

The frequencies and their intensity that an infrared camera detects is being interpreted as
heat.
