Which inspection condition improves the ability to detect missing insulation using thermography? A) Small temperature difference B) High indoor lighting C) Large indoor–outdoor temperature difference D) Low humidity Correct Answer: C) Large indoor–outdoor temperature difference Understanding the Best Inspection Condition for Detecting Missing Insulation Using Thermography Thermography is one of the most powerful non-destructive techniques used in building inspections, especially for identifying missing or defective insulation. The effectiveness of this method, however, depends heavily on inspection conditions.  Why Temperature Difference Matters Thermal imaging works by detecting temperature variations on surfaces. When insulation is missing or damaged, heat transfer becomes uneven and this is what the infrared camera captures. The key principle: The greater the temperature difference (ΔT), the more visible the thermal pattern. What Happens in Real Conditions? Winter Scenario (Best for Detection) I…
