DroneReveal also use hand-held thermal sensors for ground based thermal inspections. Thermographic building surveys offer a non-contact and non-destructive method to assess the thermal envelope of a building. Look for missing or inadequate insulation, identify under floor heating leaks and look for heat loss from doors and windows along with other thermal anomalies within the build environment.
Also ideal when looking to purchase or lease new commercial buildings. Why wait until you move in and set up all your equipment before finding problems with the building. Spot the problems before taking over the building and let someone else put right the faults.
