Infrared Imaging is a widely used technology in many different industries, from medicine to the military. Basically what this technology does is allow us to identify differences in temperature on surfaces. Why is that helpful? Well in the case of moisture intrusion, the affected area is generally cooler than an un-affected area, and can be easily seen with infrared imaging. The same is true for potential electrical problems where heat can be seen in an area where a short may be occurring.
We use this technology to help identify problem areas in a building that might be easily go undetected by a simple visual inspection.
