Thermal inspection of buildings
Detect heat loss, hidden defects and risks before they become visible.
Thermal inspection uses thermal cameras to visualise temperature differences on object surfaces. This enables fast, non-invasive identification of heat leaks, insulation defects, moisture, overheating technology and other hidden issues.

Principle
What thermal inspection is
Non-invasive diagnostics based on temperature differences — suitable for envelope checks, condition control and intervention planning.
Thermal measurement captures infrared radiation from surfaces and converts it into clear maps of thermal differences. These relate to heat loss, structural bridges, moisture phenomena or unusual behaviour of technology. For buildings, it gives a quick overview of where energy is lost, where condensation risk appears and where details should be solved before costly damage occurs.
Workflow
What the service includes
From flight and measurement through expert evaluation to a clear decision-ready output.
Data capture
- drone thermal imaging
- facade, roof and technology inspection
- RGB imagery for localisation
- night measurements
- RTK accuracy
Analysis
- data calibration
- anomaly detection
- issue identification
- defect classification
Report
- technical report
- issue marking
- repair recommendations
The RGB layer is used to anchor findings clearly to real object geometry.

Value
Benefits
Data that supports budgets, maintenance and decisions by owners or asset managers.
Energy savings
Map leaks and intervention priorities — investments go where impact is highest.
Problem prevention
Early detection of moisture, structural and operational technology risks.
Precise diagnostics
Thermal maps and RGB/RTK context reduce uncertainty in defect assessment.
Targeted repairs
Fewer “guesswork” attempts — clear zones for insulation, sealing or service.
Deliverables
Outputs
Clear materials for investors, managers and contractors in one coherent documentation package.
Thermal images
