Thermography can help you to assess areas of energy inefficiency. This is a typical room in a house.
This space shows no evidence of heat infiltration. However, thermal heat patterns can be seen elsewhere within the room. The lamp, couch and bookshelf contain intentional sources of heat to prove the sensitivity of the camera. Notice that the lamp to the left, which is on, is emitting a higher temperature (and a lighter color) than the lamp on the right, because it is off. The IR image was captured using Thermal Blending Technology (blending high resolution digital images with infrared) resulting in a clear crisp picture.
The detailing in this next image is an exceptional example of what can be achieved when using Thermal MSX Technology.
In this case, the camera identified the source of cold air infiltration (the darker colors in the picture). The problems were traced back to sloppy workmanship, which resulted in missing and sagging insulation in the walls and ceiling cavities.
