What is Thermography?
Thermography is a measurement method in which temperature differences are shown using an infrared camera, which detects, analyzes and converts wavelengths into images. A thermal camera shows people what their eyes cannot do: invisible heat radiation.
How does Thermography work?
We see objects because they reflect light. Check it out: we don’t see anything in the dark, because there is no light reflection. If we take a picture of an object, it is nothing more than a point-by-point moment representation of those light reflections. In addition to light, every object also radiates heat. We humans cannot perceive that heat, let alone the differences in heat. An infrared camera can do that.
Thanks to thermography, defects, dangers or weaknesses can be made visible.
The many possibilities are:
- Insulation values / heat & cold losses.
- Building inspections
- Detecting missing persons
- Fire fighting
- Safety check for execution of explosions
- Inventory of animals / livestock
Applications in residential construction:
- Building or renovating a house and / or business premises;
- At inexplicably high energy consumption.
- In case of uncontrolled air flows in the house (draft)
- To check the insulation shell after renovation or insulation work.
Some advantages of Thermography:
- Thermography prevents malfunctions, failures, fire or personal accidents: you identify possible problems at an early stage. This means that measures can be taken in time
- Thermography saves costs: after all, prevention is often cheaper than cure
- Thermography saves time: by registering heat differences you immediately see the cause of a problem
- Thermography is risk-covering.
The conditions for thermographic examination are:
- Thermographic research is not carried out in the summer months because the temperature of the outer shell differs too little from the inner temperature.
- The indoor temperature must be at least 10 degrees Celsius higher than the outdoor temperature.
- We cannot take a meeting in heavy rain or snow, because the moist surfaces are too cold to draw a reliable conclusion.
