Thermal Drone Inspections & Aerial Surveys
Find leaks, damp, heat loss and hidden defects fast. PV thermography, wind-turbine and building-envelope surveys delivered with full reporting.
Why Thermal?
- Reveal the invisible: Moisture ingress, insulation gaps, cold bridging and overheating components missed by visual checks.
- Prove and prioritise: Heat-map evidence targets the highest-value fixes first.
- Safer & faster: Minimise working at height and disruption to operations.
- Standards-aware: PV thermography informed by IEC 62446-3; building envelope surveys aligned to UK/EN best practice.
- UK-compliant ops: GVC / PDRA-01 VLOS operations in built-up areas (subject to airspace & site assessment).
Thermal Building Inspections
Detect damp, cold bridging, failed insulation, air leakage and pipework issues—ideal for facilities managers, surveyors and insurers.
- Façade & roof heat-loss mapping
- Flat-roof trapped-moisture screening
- Water ingress tracing
Solar PV Thermography
Rapid hotspot detection for rooftop and ground-mount PV. We flag defective modules, strings, junction boxes and soiling for targeted maintenance and recovered yield.
- Array-level heat-maps & anomaly pins
- Actionable punch-lists for maintenance
- Portfolio-scale repeat surveys
Aerial Surveys & Mapping
Orthomosaics, 3D models and volumetrics to complement thermal findings and plan remedial works.
- Orthomaps & DSM/DTM
- Cut/fill & stockpile volumes
- Progress shots & annotations
Wind Turbine Inspections
Close-in RGB and thermal inspections for towers, nacelles and blades to reduce downtime and improve safety.
- Blade leading/trailing edge & tip checks
- Thermal hotspot detection on generators & switchgear
- Condition imagery for O&M planning
Analysis & Reporting by qualified Engineers & Surveyors
GB Tech Aerial captures and analyses high-resolution thermal data to identify heat-loss, insulation failure, moisture ingress, and structural anomalies. Our engineered reports translate aerial heat-maps into quantifiable findings and clear recommendations for building surveyors, facilities managers, and asset maintenance teams.
Who We Help
- Facilities & Estate Managers
- Surveyors & Building Consultants
- PV O&M & Asset Owners
- Wind-farm Operators & O&M Teams
- Developers & Main Contractors
- Housing Associations & Property Managers
- Insurers & Loss Adjusters
How It Works
- 1) Brief: Define objectives (leaks, heat loss, PV yield, turbine condition, warranty evidence).
- 2) Plan: Site assessment, airspace checks and method statement (PDRA-01 VLOS).
- 3) Capture: Day/night flights scheduled for optimal thermal contrast.
- 4) Analyse: Thermal processing and anomaly classification. Report as required.
- 5) Deliver: Shareable web viewer, PDF report and CAD/GIS exports.
- 6) Follow-up: Repeat surveys to verify remedial works.
What You Receive
- Thermal orthomosaic and heat-loss / hotspot maps
- Pinned anomalies with photos, severity and recommended actions
- Punch-list for maintenance teams (location, access notes, priority)
- Optional: Formal thermal report
- Optional: RGB orthomosaics, 3D models and volumetrics
Compliance notes: Operations conducted under GVC / PDRA-01 within VLOS, subject to site survey, permissions and airspace requirements. PV thermography informed by IEC 62446-3. Building envelope thermography aligned with EN 13187 (qualitative detection) and superseding BS EN ISO 6781-1:2023 guidance.
