VERT / GREEN
Adequate temperature difference and anomaly cross-checked by inspection: use the image to prioritize investigation.
Infrared thermography and moisture mapping
Use infrared as a screening tool with proper test conditions, blower-door testing or moisture meters without claiming a colour pattern proves a water leak.
JAUNE / YELLOW
Reflections, sun, wind, ducts or framing can create misleading patterns: cross-check context and measurements.
ROUGE / RED
Do not open a wall or conclude mold/leakage from a thermal image alone.
Project triage
What the professional checks
- Choose test conditions and interpret patterns
- Cross-check thermography with moisture, pressure and targeted invasive inspection
