Thermal Imaging 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
Stud / Joist / Beam / Rafter placement and structure
Insulation gaps, insufficient and unevenness
Electrical drops, panels, breakers, switches and wire connections
Heating and cooling duct placement, insulation, air leaks
Pipe location
Special Inspections
Pest infestation
Energy audits
Insurance claims
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.
FTB Home inspections
goes above and beyond the standard inspection by staying on top of industry and technological changes.  The top inspectors use the best available technology.  SMHI utilizes a FLIR Infrared camera on every home inspection at no additional cost.
