Thermal Imaging, also known as Infrared Thermagrophy, are visual displays of the amount of infrared energy emitted, transmitted, and reflected by an object.
Huh? You might be thinking…right? Well simply put, thermal imaging involves the use of high tech cameras that create pictures of heat rather than light. So when used in a situation where we suspect water intrusion or a potential mold concern, these cameras help us find these areas when it isn’t clearly visible to the naked eye.
Can Thermal Imaging Find Mold?
No. Thermal imaging will detect temperature variations behind a wall to assist in finding cold spots but these very same cold spots may also indicate a potential moisture or water intrusion.
We use thermal imaging to assist in finding potential moisture problems and once we find an area of potential concern, we will then use moisture meters to confirm if there is in fact moisture behind a wall. Combined with a moisture meter, using a Thermal Imaging camera has proven to be quite effective in pinpointing water intrusion problems for our clients.
This technology may not detect mold, but it will surely help us detect a moisture problem which will assist in stopping a potential mold concern!
How does it work?
1.A special lens focuses the infrared light emitted by all of the objects in view.
2.The focused light is scanned by a phased array of infrared-detector elements. The detector elements create a very detailed temperature pattern called a thermogram. It only takes about one-thirtieth of a second for the detector array to obtain the temperature information to make the thermogram. This information is obtained from several thousand points in the field of view of the detector array.
3. The thermogram created by the detector elements is translated into electric impulses.
4. The impulses are sent to a signal-processing unit, a circuit board with a dedicated chip that translates the information from the elements into data for the display.
5. The signal-processing unit sends the information to the display, where it appears as various colors depending on the intensity of the infrared emission. The combination of all the impulses from all of the elements creates the image.
Whether you need to restore property from moisture, mold, or fire damage, you know the value of having comprehensive and accurate information at your fingertips. Insurance companies need information fast to start claims work. got mold? can give you the information so you can get your property restored properly. And you need this information so you can make estimation and reporting trouble free.
Moisture present in roofs and walls can be detected with a sensitive infrared camera, under the right conditions. Infrared roof inspections are performed most effectively after sunset, when the roof gives off its heat energy accumulated during the day. The heat capacity of moisture soaked roof insulation is greater than that of dry insulation. As a result, the moisture soaked roof areas appear quite clearly when performing an infrared scan.
Similarly, it is possible to detect moisture located behind interior walls with an infrared camera, under the right conditions. The temperature difference created by the presence of moisture on the inside surface of a wall will appear differently than the surrounding area.
Infrared inspection is a fast, non-invasive method to discover moisture intrusion within the building envelope. Infrared inspection does not directly detect the presence of mold, rather it may be used to find moisture where mold may develop. The limitations to obtaining accurate infrared images pertain to the ability of the surface being scanned to emit heat energy. Gypsum (dry wall) in interior walls emits quite well, whereas highly reflective surfaces do not. Since the temperature difference between the wet and the dry wall are very slight, a sensitive infrared camera must be used.
