While there is no guarantee that nothing will be missed during the visual inspection. Thermal imaging brings me one step closer to not overlooking anything!
What is it?
Infrared (thermal imaging) is an advanced, non-invasive technology that allows the inspector to show clients things about their homes or buildings that can't be revealed using conventional inspection methods. Ancillary inspection reports are just as important as the reports generated for standard inspections.
Benefits of Thermal Imaging in the detection of:
Water infiltration (roof leaks located with recent rain fall within 24~48 hours) * Cold air infiltration
Excessive moisture in building materials
Insulation gaps, insufficient and unevenness
Electrical drops, panels, breakers, switches and wire connections Heating and cooling duct placement, insulation, air leaks Pipe location
Stud / Joist / Beam / Rafter placement and structure
As you study the photos below, I remind you, these images would not be visible without the aid of a thermal imaging camera. Which is included in all my inspections!
Thermal imaging only displays surface temperatures of solid objects. IR detects the temperature based upon wavelength of the light emitted by the object (longer wavelength, colder). IR, therefore, does not show the temperature of objects that reflect light, (glass, shiny metal, light colored objects in direct sunlight). IR, does not “see through walls”, but only displays the very slight differences in surface temperature of the wall. Images of areas “behind” and not in contact with walls depends upon the temperature difference of the area. It is easier to see “hot” objects because they will be radiating heat to the not-in-contact surface. See pictures below for how IR is still incredibly useful. * Careful adjustment of the range of temperatures displayed is important to proper imaging and interpretation. (but don’t worry: I have been trained to do this).
