A thermal imaging camera is a valuable tool that shows images in the form of temperature differences.  This allows the auditor to see drafts, missing or ineffective insulation, and even sources of heat loss such as an un-insulated heat pipe.  This camera allows us to see through walls and understand how the home is insulated, where air leakage occurs, and to locate trouble spots throughout the house.  This process allows the auditor an in-depth look at every inch of your home that would not be possible to explore using conventional methods.
