Measure an interior partition wall surface temperature.
Do not release the trigger. Record this temperature
as your baseline (or benchmark) for a “perfectly”
insulated wall.
Face the wall to be scanned. Stand 1.5m away to
scan a 5cm spot on the wall.
Scan horizontal rows of wall from top to bottom, or
horizontal rows of ceiling from wall to wall. Look for
greatest deviations from baseline temperature to
identify problems. This completes the insulation test
scan.
